Hi,I'm working on a project where Raspberry Pi together with Xbee s2 (if possible) will work as a coordinator. On the RPI there will be a frontend and node js backend hosted. I want to use xbee module s1 or s2, as I already have a few. For the end de...

Hi,I have spent a few days trying to get the timers in sync, that is use one timer with multiple outputs; oc,PWM,base. I am generating a 1MHz clock for an external device. And then a start pulse. When the timer overflows ADC starts. It needs to be ex...

OK, Ive done it and now Im trying to use the stm32 dongle with zigbee2mqtt on RPi. How can I skip running user program and use configure RPi as coordinator. I basically want to use only the zigbee stack from the dongle.

I've found the problem. Firstly, the screen had a tiny crack, not easily visible. I've purchased another display, but it wasn't working. It turns that there are two PB2 pins. Only one works as MOSI. I've connected the first one to the correct pin, so...

Sorry I meant xpt2046. Spi works, I use it for the TFT. I've ported the drivers for stm32f and none of the three different drivers worked.

Thanks, Ive actually managed to port the display, unfortunately the touch screen doesn't work. I ve checked SPI and ehrn I dont connect miso/mosi external interrupt works, but once I connect it, it triggers without touching.

STM32WB Zigbee to Raspberry Pi Xbee connection

Nucleo board with STM32H7A3 - ADC and OpAmp I know the maximum sample rate for direct , fast and slow channels. But what if I use an opamp in the follower mode and connect it internally to ADC. Is my sample rate the same as for slow channels?

Timers first pulse is different and timers not in sync

STM32H7A3 on Nucleo board - XPT2046 Touch doesnt work

Hi Ive been trying to port a display driver ili9341 on STM32H7A3zi-q for a long time but I cant get it to working. I'd be grateful if someone already did it and could share the driver. Cheers, Dan
