Report Simple send to an serial port in Brainstorming Posted February 5, 2019 I do not see this as such a big problem, because if you can put together the data you need, similar to the LCD's and only relavantes further, the string should not be too long. For what I imagined, that would be: - CPU load - CPU temperature - GPU load - GPU temperature - RAM occupancy The string could look like this: 25;55;30;45;3545; or: CL25,CT55,GL30,GT45,R3545; So only the most necessary joined together with separators. That makes 36 characters in the constelation, that is 360 bits. Maximum update at 9600 baud: 26 / s. But that's not all that much, since such ads are rather crude and sluggish. Apart from that, even the small Arduino Uno creates the 115000 baud.
