Add delay() in plotter examples

Open wh201906 opened this issue 2 years ago • 4 comments

What This PR Changes

This PR adds delay() in the examples of software/ide-v2/tutorials/ide-v2-serial-plotter The original examples doesn't have delay() in the loop(), which is fine for the boards with hardware serial ports. The baudrate (9600) limits the data speed. normal However, for boards with USB serial port, the baudrate doesn't take affect. The board will send data to the PC at the maximum speed. too_fast

I set the delay timeout as 20ms because the original example takes around 32ms to send a frame to the hardware serial. (9600baud,8N1->960Bytes/s, ~31bytes per frame, (31B)/(960B/s)≈32.292ms) With the delay(20), the plot speed of the hardware serial won't go too slow, but the speed of USB serial is throttled to the same order of magnitude as the hardware serial's.
