Arduino for STM32

Thank you, this was a bit not intuitive for me but it works now

done
https://github.com/stm32duino/Arduino_C ... ssues/2632

setRx/Tx seems like not works for me

I also tried to change clocks

SB16 and SB17 are on.
without while(!Serial); it does not blink for both Serial and SerialUSB (USB support (if available): CDC (generic 'Serial' supersede U(S)ART))
according to https://os.mbed.com/platforms/ST-Nucleo-H7A3ZI-Q/
PD9 and PD8 are Tx and Rx of UART4
I set:
#define PIN_SERIAL_RX PD8 ...

I don't know if it's related to this problem or not but serial communication seems not works properly.
Example:

#define ledPin PB0

void setup() {
Serial.begin(9600);
while(!Serial);
pinMode(ledPin, OUTPUT);
}

void loop() {
digitalWrite(ledPin, !digitalRead(ledPin));
delay(100);
Serial ...

I did several tests and both yours and mine branches works.
I just realized that LED_BUILTIN is PNUM_NOT_DEFINED and not PB0.
Thank you for support

Code: Select all

- maximum_data_size=1458176
+ maximum_data_size=1048576

changed but same problem, after upload no reaction.

@fpiSTM
thank you for response,
I will do the tests and report the issue

It happened automatically in my case.
Now I have similar problem as the author.
Upload the blink sketch and nothing happens.
Before that I had some problem in generic_clock.c with unknown PWR_DIRECT_SMPS_SUPPLY.
fixed with:
#define PWR_CR3_SMPSEN_Pos (2U)
#define PWR_CR3_SMPSEN_Msk (0x1UL << PWR ...

Thank you for the hint.
Removing arduino-ide folder from AppData helps BUT after all the changes and before close IDE need to remove link from Preferences

If not then all changes will be overwritten ...
