On My PC RS232terminal I now receive some "garbage"...

Hi Martin and others I started a new Thread because have problems using some third party interfaces with OrangePI running Armbian. Well.. In my project I need to communicate with 5 sensors which have UART output so I decided to buy a circuit (uart2spi) which work well if connected to Arduino. The Circuit description is available here: http://www.rowlandtechnology.com/projects/2015/09/25/spi-to-4-x-uart-bridge-multiuart-project/ First step: This is how I have connected the circuit to GPIO bus on my OrangePi pc.. The circuit has (from left to right) +3.3V pin, MISO, MOSI, SCK (clock), CS and GND.. I have connected those wires to GPIO pins: +3.3V to pin 17 MOSI to pin 19 MISO to pin 21 SCK to pin 23 CS to pin 24 (chip select) GND to pin 20 This is how it look like... (the green led on my interface is on so it's mean that power is on) If I look at the tutorial on how to setup the board on Arduino is the same (you just connect wires) except CS is some output pin which you can togle on/off.. in my case I have connected those wire to orangepi on pin 24 (CE0).. Now I would like to port Arduino library to C and here the problems begin... first... the initialization of SPI... In Arduino I have this kind of method (SPIDivider is set to 250000 (250 kHz)) Arduino code: void MULTIUART::initialise(int SPIDivider) { SPI.begin(); SPI.setBitOrder(MSBFIRST); SPI.setClockDivider(SPIDivider); } and here is my code in C but I don't know if this is the right way to write over spi? and also how to set-up bitOrderMask (if needed)? Orangepi code : #include <iostream> #include <stdint.h> #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <getopt.h> #include <fcntl.h> #include <sys/ioctl.h> #include <sys/times.h> #include <linux/types.h> #include <linux/spi/spidev.h> #include <spi_lib.h> using namespace std; #define ARRAY_SIZE(a) (sizeof(a) / sizeof((a)[0])) static const char *device = "/dev/spidev0.0"; static uint8_t mode = 3; static uint8_t bits = 8; static uint32_t speed = 250000; //250kHz static uint16_t delays; static void pabort(const char *s) { perror(s); abort(); } int main(int argc, char** argv) { int ret = 0; int fd; fd = open(device, O_RDWR); //read write if (fd < 0) { printf("can't open device"); return -1; } ret = ioctl(fd, SPI_IOC_WR_MAX_SPEED_HZ, &speed); if (ret == -1) { printf("can't open device"); return -1; } printf("spi mode: %d\n", mode); printf("bits per word: %d\n", bits); printf("max speed: %d Hz (%d KHz)\n", speed, speed / 1000); if (ioctl(fd, SPI_IOC_WR_MODE, &mode) == -1) pabort("Can't set SPI mode"); close(fd); return ret; } from console i get: now... Here I have a function from Arduino to set BaudRate for specified channel on my interface. (baud rate is selected with values from 0 to 7 (0=1200, 1=2400, 2=4800, 3=9600, 4=19200, 5=38400, 6=57600, 7=115200)) This function works well on Arduino (but.... if you see it uses digitalWrite command to pull down the signal on CS pin and then the command is send over SPI.transfer function.. ) void MULTIUART::SetBaud(char UART, char BAUD) { if (UART < 4) { if (BAUD < 10) { digitalWrite(_ss_pin, LOW); SPI.transfer(0x80 | UART); delayMicroseconds(50); SPI.transfer(BAUD); digitalWrite(_ss_pin, HIGH); delayMicroseconds(50); } } } Now I don't know if the same must be done on OrangePI with CS pin (pin 24 on GPIO or is this done by kernel)? I have ported this code above on orangepi like this: void setBaudRate(int fd,char uart) { if (uart <4) { int ret = -1; uint8_t tx_buffer_baud = (uint8_t)(0x80|uart); //??? CS pin must be in LOW mode ret = spi_write(fd,&tx_buffer_baud,1); printf("ret1: %d\n", ret); usleep(50); tx_buffer_baud = (uint8_t) 3; ret = spi_write(fd,&tx_buffer_baud,1); usleep(50); //??? CS pin must be in HIGH mode printf("ret1: %d\n", ret); } } So is the CS pin set to LOW before the command is send over SPI or it must be done manually? thank you for any info..

Hi, need some help.. I'am familar with Java but with c/c++ not So.. have downloaded source from: https://github.com/duxingkei33/orangepi_PC_gpio_pyH3 to my orangepi.. Than I have installed the library with python and all is ok.. On the remote PC I have setup Netbeans IDE and now want to include gpio_lib.h The problem is that IDE can't find header files in directories listed below... So.. what is the procedure to use orangepi_PC_gpio_pyH3 library? Can I only copy/paste files to /usr/include folder on my OP?

Can you explain how to recompile headers? thank you

Hm.. ok.. thank you Igor..

this is the result ...

The same is with debian..

I found the implementation here (It's for arduino but should work also on orangepi with some modifications): https://github.com/RowlandTechnology/MULTIUART or maybe to use MAX14830 (https://www.maximintegrated.com/en/products/interface/controllers-expanders/MAX14830.html) 4 uarts to SPI http://www.spinics.net/lists/linux-serial/msg10232.html I'm working on scientific project where we must acquire datas over 5 uarts. Each uart is connected to specific sensor (oxygen, temp, salinity, pressure, chlorophile,..)..

Hi, I need to connect this kind of board over SPI bus to Orange PI: http://www.instructables.com/id/SPI-to-4-x-UART-Bridge-MULTIUART/ Can I use the https://github.com/duxingkei33/orangepi_PC_gpio_pyH3 libraries to talk over SPI bus? regards Peter

Hi, Have Arduino (microcontroller) clone with CH340 USB/UART (USB serial port). Does armbian support it? regards Peter

Hi, for my project I need to stream a video from IP camera and add some text from sensors into the final video. From armbian console I have installed ffmpeg (apt-get install ffmpeg).. The program works except the text is not included into streamed video: Example: ffserver.conf HTTPPort 8090 HTTPBindAddress 0.0.0.0 MaxHTTPConnections 2000 MaxClients 1000 MaxBandwidth 10000 CustomLog - <Feed monitoring1.ffm> File /tmp/monitoring1.ffm FileMaxSize 50M ACL allow 127.0.0.1 ACL allow 192.168.0.0 192.168.255.255 </Feed> <Stream monitoring1.mjpg> Feed monitoring1.ffm Format mpjpeg VideoCodec mjpeg VideoFrameRate 22 VideoBufferSize 80 VideoSize 720x264 NoAudio </Stream> # Redirect index.html to the appropriate site <Redirect index.html> URL http://www.ffmpeg.org/ </Redirect> Then I start a simple example as: ffmpeg -i rtsp://mpv.cdn3.bigCDN.com:554/bigCDN/definst/mp4:bigbuckbunnyiphone_400.mp4 -vf drawtext="fontfile=/home/projekt/StreamTest/DejaVuSans.ttf: \ text='TEST TEST': fontcolor=white: fontsize=36: box=1: boxcolor=black@0.5: \ boxborderw=5: x=(w-text_w)/2: y=(h-text_h)/2" -codec:a copy http://localhost:8090/monitoring1.ffm In Armbian console I get: root@orangepipc:/home/projekt/StreamTest# ./test.sh ffmpeg version 3.2.2-1~bpo8+1 Copyright (c) 2000-2016 the FFmpeg developers built with gcc 4.9.2 (Debian 4.9.2-10) configuration: --prefix=/usr --extra-version='1~bpo8+1' --toolchain=hardened --libdir=/usr/lib/arm-linux-gnueabihf --incdir=/usr/include/arm-linux-gnueabihf --enable-gpl --disable-stripping --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --disable-libebur128 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libiec61883 --enable-libopencv --enable-frei0r --enable-libx264 --enable-chromaprint --enable-shared libavutil 55. 34.100 / 55. 34.100 libavcodec 57. 64.101 / 57. 64.101 libavformat 57. 56.100 / 57. 56.100 libavdevice 57. 1.100 / 57. 1.100 libavfilter 6. 65.100 / 6. 65.100 libavresample 3. 1. 0 / 3. 1. 0 libswscale 4. 2.100 / 4. 2.100 libswresample 2. 3.100 / 2. 3.100 libpostproc 54. 1.100 / 54. 1.100 [rtsp @ 0xb7a0a280] UDP timeout, retrying with TCP Input #0, rtsp, from 'rtsp://mpv.cdn3.bigCDN.com:554/bigCDN/definst/mp4:bigbuckbunnyiphone_400.mp4': Metadata: title : http/9aaa4066-cs.mi-cdn.io/streaming/streams/flash/bigbuckbunnyiphone_400.mp4 Duration: 00:09:56.46, start: 0.000000, bitrate: N/A Stream #0:0: Audio: aac (LC), 48000 Hz, stereo, fltp Stream #0:1: Video: h264 (Constrained Baseline), yuv420p(progressive), 320x180, 24 tbr, 90k tbn, 180k tbc [tcp @ 0xb7a11ca0] Connection to tcp://localhost:8090 failed (Connection refused), trying next address Last message repeated 1 times [swscaler @ 0xb7a61d10] deprecated pixel format used, make sure you did set range correctly Output #0, ffm, to 'http://localhost:8090/monitoring1.ffm': Metadata: title : http/9aaa4066-cs.mi-cdn.io/streaming/streams/flash/bigbuckbunnyiphone_400.mp4 creation_time : now encoder : Lavf57.56.100 Stream #0:0: Video: mjpeg, yuvj420p(pc), 720x264, q=2-31, 64 kb/s, 24 fps, 1000k tbn, 22 tbc Metadata: encoder : Lavc57.64.101 mjpeg Side data: cpb: bitrate max/min/avg: 128000/0/64000 buffer size: 655360 vbv_delay: -1 Stream mapping: Stream #0:1 -> #0:0 (h264 (native) -> mjpeg (native)) Press [q] to stop, [?] for help [mjpeg @ 0xb7b0f760] rc buffer underflowkB time=00:00:00.77 bitrate= 720.9kbits/s dup=0 drop=1 speed=1.51x Last message repeated 8 times [mjpeg @ 0xb7b0f760] rc buffer underflowkB time=00:00:01.27 bitrate= 720.9kbits/s dup=0 drop=2 speed=1.24x Last message repeated 6 times Past duration 0.719322 too large [mjpeg @ 0xb7b0f760] rc buffer underflow Past duration 0.795326 too large [mjpeg @ 0xb7b0f760] rc buffer underflow Past duration 0.893318 too large [mjpeg @ 0xb7b0f760] rc buffer underflow Last message repeated 1 times [mjpeg @ 0xb7b0f760] rc buffer underflowkB time=00:00:01.77 bitrate= 739.4kbits/s dup=0 drop=3 speed=1.15x Last message repeated 8 times [mjpeg @ 0xb7b0f760] rc buffer underflowkB time=00:00:02.18 bitrate= 750.9kbits/s dup=0 drop=3 speed=1.06x Last message repeated 3 times frame= 53 fps= 23 q=31.4 Lsize= 224kB time=00:00:02.36 bitrate= 776.3kbits/s dup=0 drop=4 speed=1.04x video:217kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 3.163595% Exiting normally, received signal 2. root@orangepipc:/home/projekt/StreamTest# This is the result of "streamed" video but without embedded text 'TEST TEST' Does anyone know what could be wrong? or how to get latest version of Ffmpeg?

Thank you will check..

uuu thank you...

I get the same values:

Will try to upgrade ... sed -i "s/apt/beta/" /etc/apt/sources.list.d/armbian.list apt-get update apt-get upgrade

Thank you for your help! here is for: ls -l /boot/dtb/overlay I don't have subdirectory dtb dmesg | grep serial cat /proc/device-..... (I don't have this folder) thank you for your help. I don't have much experience in linux but must do a project for thesis ;(

Have tryed also with python but here I get nothing Have installed Serial lib from https://pypi.python.org/pypi/pyserial

Hmm.. tryed but still get only one serial cmd : cd '/home/projekt/NetBeansProjects//TestCom'; '/usr/bin/java' -Dfile.encoding=UTF-8 -jar /home/projekt/NetBeansProjects//TestCom/dist/TestCom.jar ------------------------------- 1.7.0_121 Linux /dev/ttyS0 - Serial

Ok! will this be fine? will try.. thank you verbosity=7 console=both machid=1029 bootm_boot_mode=sec rootdev=UUID=74434014-190f-406c-9b73-2c99c49383ba rootfstype=ext4 overlays=sun8i-h3-uart1 sun8i-h3-uart2 sun8i-h3-uart3

Hi, In my project I want to use UART on GPIO pin (8,10). I wrote a simple Java app to decet serial ports on my orange PC but it return only /dev/ttyS0 - Serial Here is simple java code using rxtxlibrary.. package org.mbp; import gnu.io.CommPortIdentifier; /** * * @author Peter */ public class TestCom { /** * @param args the command line arguments */ public static void main(String[] args) { System.out.println("-------------------------------"); System.out.println(System.getProperty("java.version")); System.out.println(System.getProperty("os.name")); java.util.Enumeration<CommPortIdentifier> portEnum = CommPortIdentifier.getPortIdentifiers(); while (portEnum.hasMoreElements()) { CommPortIdentifier portIdentifier = portEnum.nextElement(); System.out.println(portIdentifier.getName() + " - " + getPortTypeName(portIdentifier.getPortType())); } } static String getPortTypeName(int portType) { switch (portType) { case CommPortIdentifier.PORT_I2C: return "I2C"; case CommPortIdentifier.PORT_PARALLEL: return "Parallel"; case CommPortIdentifier.PORT_RAW: return "Raw"; case CommPortIdentifier.PORT_RS485: return "RS485"; case CommPortIdentifier.PORT_SERIAL: return "Serial"; default: return "unknown type"; } } } Whe I run the code on orangepiPC I get only one UART which is /dev/ttyS0 ------------------------------- 1.7.0_121 Linux /dev/ttyS0 - Serial Is there some configuration file to enable / disable UARTS? thank you.

Jap.. my goal is to have Arduino connected over Gpio to orangpi pc.. (using pin 8 and 10). I'am using arduino to measure frequency up to 15 kHz (have some temp/salinity sensors which gives me frequency on the output). The measured frequency is then send over serial port to "third" components in my case will be Orangepi.. I have experience with Java so I think I can use RxTx library to read data from serial port ( /dev/ttyS3)? $ sudo apt-get install librxtx-java

Thank you! will try it..
