I don't know about speed, but some of the Braswell pins (pins 24-29) are 3.3 V not 1.8. See...
Updated pinout table for gpio,I2c and Uarts
Updated/corrected table of gpio/uart/I2c ports
Oops! I mis-wrote my addendum. There are 3 external gpio lines not controlled by gpiochip 3. Pins 36 and 37 are on gpiochip 0, pin 40 on...
As I noted above, the permissions give you the ability to cause major havoc. If the you look at the gpio table, all but 1 of the external gpio...
If I update the https://github.com/UDOOboard/X86II-Docs will it update this link?
SEE https://www.udoo.org/forum/threads/braswell-gpio-number-correction.32374/ for a correction to the docs
In a previous post https://www.udoo.org/forum/threads/using-braswell-gpio-i2c-and-uart-pins.32423/ I discussed the use of the libgpiod library,...
I have verified that pySerial does work. As the documentation states use ttyS4 for Uart1. Under linux (Mint) you have to disable the "Virtual...
would it be appropriate to cross post my Braswell GPIO correction thread to this thread?
Libgpiod is available from several distros. C++ and python bindings are available and I have submitted a pull request to the Adafruit_Blinka...
Searching for information on using the GPIO has been fairly daunting. The user docs refer the the...
Correction, the 5th line should read : echo 0 | sudo tee /sys/class/gpio/value In the spirit of updating the documentation, there are 2 places in...
Look it's easy to verify. Take a digital volt meter, attach it to ground and pin 36 . Then type: echo 492 | sudo tee /sys/class/gpio/export...
Is there any body there!
The pinout for the Braswell Gpio numbers in the documentation https://www.udoo.org/docs-x86II/ has 2 errors. It maps physical pin # 36 to GPIO...
