Arduino Clear Serial

Check if the Serial Transmission Is Done or Not Using the Serial.flush Function in Arduino When we transmit data from serial, the data is placed in a buffer, and the program moves to the next statement, and the data is transmitted slowly from the buffer because serial is slow. I’m starting to build my first Arduino project but I’m running into some problems with serial communication. I get serial data from the console and store it in a char array called ’data’. Then, when I send a new console message to the Arduino, I want it to clear the existing ’data’ array and store only the new data in that array. Not knowing what virtual breadboard does on a normal Arduino it would do the following: Serial.flush clears the buffer and this needs some time normaly you wait minimum for around 100 ms to write/read to that buffer again. As your code runs in setup (so just once) the serial is not available as its still flushing and so your result.Description
Serial.readBytes() reads characters from the serial port into a buffer. The function terminates if the determined length has been read, or it times out (see Serial.setTimeout()).
Serial.readBytes reads characters from the serial port into a buffer. The function terminates if the determined length has been read, or it times out (see Serial.setTimeout ). Serial.readBytes returns the number of characters placed in the buffer. A 0 means no valid data was found. Serial.readBytes inherits from the Stream utility. To clear the screen in a terminal emulator, a standard clear screen command is (esc) 2J, so your code would look like this: Serial.print (27,BYTE); //Print ’esc’ Serial.print (’ 2J’); This will not work in the Arduino Serial Monitor, so you need a terminal emulator. Since it doesn’t use a serial port, you also need a serial port emulator.

The number of bytes placed in the buffer. Data type: size_t.Hi,
Scott here from Salem. My program goal. Press 1 on the key board and an led lights up on the arduino. Press 2 and it goes off. Press anything else and the command port prints out ’invalid’. I then want to clear the serial port to erase anything else, because if I press a bunch of numbers e.g. 3456, it prints out invalid several times. I would like it to print out invalid only once. I read that Serial.flush() no longer works. I have tried byte = discard Serial.read() but this does not work. Can someone help me with how to flush the serial port of the remaining data?Arduino Clear Serial Read Buffer
