WebMar 9, 2024 · In arduino, there is a function Serial.Available() to check if the serial buffer is empty or not. Is there a function in STM32 that is similar to Serial.Available() in Arduino?

WebOct 10, 2014 · But it is inside a for loop, so the first bit of buffer, aka buffer[1], will be assigned all of serial.read(), then the second bit of buffer, aka buffer[2], will be assigned all of serial.read() etc. This is impossible as buffer[i] is a bit, and serial.read() is a byte. It's the for loop which confuses me really. Can you please explain this to me?
