Here's what I found out maximum speed for SPI 33 MHz this is defined in script.bin .The next command, I set the SPI for speed 5MHz spi.open("/dev/spidev1.0", mode=0, delay=0, bits_per_word=8, speed=500000) . Speed is set in Hz and not in kHz, as in the library wrote !!! When setting the speed above 6 megahertz, the screen starts to slow down .In reality, if the SPI speed is set to 10 Mhz, it starts to work worse than at 5 Mhz.

The maximum speed of spi for orange pi zero? My logical analyzer shows the maximum speed at SPI1_CLK/PA14 about 5 MHz It's not enough for me . This screen can work above 10 MHz. My settings in the program spi.open("/dev/spidev1.0", mode=0, delay=0, bits_per_word=8, speed=100000) this is 100 MHz , but I have in reality only 5 MHz CLK.

What is the maximum SPI speed?

Has connected the display. What is the maximum SPI speed? The library can send parcels of 8 bits, how to change to 16 bits? I mean spi.write([0x00FF]) it's not possible ? Only spi.write([msb,lsb]) possibly.

#!/usr/bin/python import time from pyA20.gpio import gpio from pyA20.gpio import port from pyA20.gpio import connector gpio.init() gpio.setcfg(port.POWER_LED, gpio.OUTPUT) while True: gpio.output(port.POWER_LED, gpio.HIGH) time.sleep(0.25) gpio.output(port.POWER_LED, gpio.LOW) time.sleep(0.25) WHY THIS CODE DOES NOT WORK !!!???

STATUS_LED and POWER_LED defined in mapping.h . What's about EPHY-LINK-LED(A2) and EPHY-SPD-LED(F7) is it possible?

Installed tightvncserver and sudo apt-get install xfonts-base. When I try to connect and see the "foto". How can I fix this?

It works with some restrictions in the free version. While connected usb camera. 30% processor load. Soon I will try to connect ip camera.

I read this post http://felenasoft.com/xeoma/en/articles/raspberry/ Whether it will work for armbian?

How to make a copy (backup) flash drives with installed operating system on it ? I need a program for windows.

Yes you are right (as I understand it is configured). Now how can I use it using C language or Python. cat /dev/ttyS0|tee my-data Will it work?

(jessie 3.4.112-sun8i) How to use debug TTL UART(three pins next to the power jack )?

Solved sudo apt-get install idle

(jessie 3.4.112-sun8i) sudo apt-get install idle idle-python2.7.9 gives me an error E:Unable to locate package idle-python2.7.9. E:Couldn'n find any package by regex 'idle-python2.7.9' What am I doing wrong?
