Hi to all, I was wondering if it is possible to receive serial communication through the stlink bridge of the nucleo. In fact, is possible, and I already provided a pull request for the change. I hope it helps a little for the testing of the new PoElli in the next weeks. Please, test accordingly :) mkdir temp cd temp git clone https://github.com/supramaterial/Runtime.git cd Runtime/stm32/build/ make sketch.cpp #then, for testing, modify the sketch.cpp to something like this: ##--------------------------- #include <Arduino.h> void setup() { Serial.begin(57600); } void loop() { Serial.write('H'); Serial.write('e'); Serial.write('l'); Serial.write('l'); Serial.write('o'); Serial.write('\r'); Serial.write('\n'); for (volatile int i = 0; i < 100000; i++) ; } ##------------------------ #then make VARIANT=stm32f334nucleo #and flash sudo st-flash write hardware/stm32f334nucleo/sketch.bin 0x8000000 #the good part is that the stlink controller provides the USART2 through #the usb, in linux it shows as /dev/ttyACM0 #now, to test, use a serial console, minicom, for example #if minicom not installed sudo apt-get install minicom sudo minicom -s #go to "serial port setup" #configure in this way +------------------------------------------ | A - Serial Device : /dev/ttyACM0 | B - Lockfile Location : /var/lock | C - Callin Program : | D - Callout Program : | E - Bps/Par/Bits : 57600 8N1 | F - Hardware Flow Control : No | G - Software Flow Control : No | | Change which setting? +------------------------------------------ #then "save setup as dfl" #and run minicom sudo minicom #it should show "hello" iteratively With Warm Regards, Ivan Raul
