Support STM32F105RCT6

[CzokNorris]

I am using version stm32duino version 2.4.0
My Arduino IDE is 1.8.19
The chip is STM32F105RCT6 on a custom board

When I
digitalWrite(36, HIGH);
or for example
digitalWrite(PC_7, HIGH);
the program stops running on my board.
And I have checked. The pin names are wrong.

4 is supposed to be PA4, but in reality toggles PB5 (package pin 57)
5 is supposed to be PA5, but in reality toggles PB4 (package pin 56)
(supposed to be is taken from here: https://github.com/stm32duino/Arduino_Core_STM32/blob/main/variants/STM32F1xx/F105R(8-B-C)T/variant_generic.cpp)
I have not checked the other leds.

This sketch stops running after 10 seconds (led stops blinking):
#define LED2 PB3

#define SimpleSwitchOutControl PC_7

void setup() {
//LEDs: When driven LOW, they are off. When driven HIGH, they are illuminated
pinMode(LED2, OUTPUT);
pinMode(SimpleSwitchOutControl, OUTPUT);

digitalWrite(LED2, LOW);

}

void loop() {
if (millis() % 1000 < 100){
digitalWrite(LED2, HIGH);
}else{
digitalWrite(LED2, LOW);
}

if (millis() > 10000){
if (millis() % 2000 < 1000){
digitalWrite(SimpleSwitchOutControl, HIGH);
}else{
digitalWrite(SimpleSwitchOutControl, LOW);
}
}

}

Didnt see that Board part number can be edited. Leaving it here however, because the F105 is not in the list. Is there a way to add it to the list. Selected F103RCT from the list and now this error is not appearing

Hi,

First your sketch is not correct, you used PinName instead of pin number. So instead of PC_7 you have to use PC7.
To add a variant you can follow this wiki:
https://github.com/stm32duino/wiki/wiki/Add-a-new-variant-(board)

I've added the STM32F105RCT6 to the request list #722
