Even applying thermal patch cpu temperature stays at 80+C which initiates core shutdown. Currently I am on armbian 5.04 and ambient temperature is 33C which may go upto 45. I am working on video streams with OP that consumes lots of CPU and other resource which triggers temperature. Planning to stream from moving vehicle (OP will be fitted in moving vehicle). Please help/guide me to select heat sink which should accept some vibrations and jerks from vehicle. Note : OP don't have provision like screw hole or attachment for heat sink. Thanks, Yogesh

Thanks ..Let me add more verbose instruction with photo and add this as tutorial to forum.English is not first language so it will take some time I have some interesting stuff in home lab and in coming days I will like to make them working under Armbian.

I have successfully tested i2c on Armbian 5.04 with RTC 3231 module Device used : RTC DS3231 Here is the quick steps. 1. Using out of the box OS settings. Connecting RTC to OPO DS3231 OP One GND ——————————> pin 06 (GND) Vcc ——————————> pin 01 (3.3V) SDA ——————————> pin 03 (I2C SDA) SCL ——————————> pin 05 (I2C SCL) 2. List i2c adapter root@orangepione:/boot# i2cdetect -l i2c-0 i2c twi0 I2C adapter i2c-1 i2c twi1 I2C adapter 3. DS3231 present at address 0x68 on twi0 adapter root@orangepione:/boot# i2cdetect -y 0 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- 57 -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- root@orangepione:/boot# i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- 4. OS time synchronization over NTP ( OS Default) root@orangepione:/boot# date Tue Mar 1 20:50:24 CET 2016 5. Add ds3231 to system. Add "echo ds3231 0x68 > /sys/class/i2c-adapter/i2c-0/new_device " to /etc/rc.local before exit 0 6. root@orangepione:/boot# reboot 7.

i missed that ... let me try the spi library of orangepi_PC_gpio_pyH3

you need to remove RPi.GPIO if installed .

my bad ... replace the reference import RPi.GPIO as GPIO with import pyA20.gpio as GPIO in MFRC522.py MFRC522-python package use RPi.GPIO and we are replacing it with orangepi_PC_gpio_pyH3 (pA20.gpio ).

I am able to test SPI successfully with 5.04 release. Device used : RFID Reader RC522 Here is the steps to followed : 1. Connection Mifare_RC522_RFID OP One MOSI ——————————> pin 19 MISO ——————————-> pin 21 SCLK ——————————-> pin 23 SDA ——————————–> pin 24 RST ———————————> pin 22 IRQ ———————————-> NONE 2. Check device ls /dev/spidev0.0 ( Armbian 5.04 gives it out of the box) 3) Install python dev apt-get install python-dev 4) Install orangepi_PC_gpio_pyH3 Library git clone https://github.com/duxingkei33/orangepi_PC_gpio_pyH3.git cd orangepi_PC_gpio_pyH3 python setup.py install 5) Install SPI-Py Library git clone https://github.com/lthiery/SPI-Py.git cd SPI-Py python setup.py install 6) Install MFRC522-python git clone https://github.com/rasplay/MFRC522-python.git 7)To read id data: cd MFRC522-python edit MFRC522.py and comment out line 108.109.110 and 356( as shown below) # GPIO.setmode(GPIO.BOARD) #GPIO.setup(22, GPIO.OUT) #GPIO.output(self.NRSTPD, 1) #GPIO.output(self.NRSTPD, 1) python read.py root@orangepione:~/MFRC522-python# python read.py Card read UID: 193,11,21,149,74
