UART or GPIO Reprog
I'm working on a drone project (PX4Vision) which uses the Intel Up Core board as a companion computer and I have a question regarding the GPIO.
Is it possible, like on a RaspberryPie, to reconfigure the usage of GPIO pins ?
I'd like, for instance, to reconfigure the UART0 pins into simple on/off GPIO pins to use them as interruption "button". Is it possible and if yes in what file this config is made (and what about the reboot) ?
Thanks in advance
Hi @Vinco ,
The default UART0 pins 9 and 10 on CN7 cannot be reconfigured. For GPIO controlling, we suggest to use ISH_GPIO via docking 100-pin header (1.8v level). Kindly refer to the UP Core Pinout
thanks a lot for your answer, helps me so much.
So all the ISH-GPIO are available for programming right ? If there are a part of the 100-pi header how can I physically access them (like to wire them) ? are there reachable via an additional carrier-board for instance ?
Hi @Vinco ,
Yes they are available for programming. You can access them using a cable connected to a carrier board.
You can find the carrier board on the UP Shop
Great thanks a lot.
Unfortunately I just realized that I have a customized version of this carrier board, and it only gives access to I2C, SPI, UART and USB but all the GPIO seem unused and unreachable through the carrier board...
Thanks anyway I found the answer I was looking for !
