I have started a new project. (PlatformIO Core 6.1.11
Home 3.4.4
)
Platformio.ini:
[env:genericSTM32F103C8]
platform = ststm32
board = genericSTM32F103C8
framework = arduino
debug_tool = stlink
upload_protocol = stlink
monitor_port = COM31
monitor_speed = 115200
lib_deps =
build_flags =
-D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC
-D USBCON
;monitor_dtr = 1
Uploaded this small code to the Bluepill:
#include <Arduino.h>
void setup() {
// put your setup code here, to run once:
SerialUSB.begin();
}
void loop() {
// put your main code here, to run repeatedly:
delay(1000);
SerialUSB.println(“ModbusSlaveTest”);
}
With the above .ini and small code, I can’t connect to the USB port
If I upload an older code to the same board, the USB port works fine.
What can I do to make the USBSerial work again ?
Thanks in advance
