Trying to wrangle serial data from an Arduino

[GoToLoop]

Using two different readStringUntil "characters"

The solution I gave on that link expects the Arduino C code to send the multi-data as if they were a row of tab-separated values (TSV): That is, each value is followed by a \t character; except last 1, which is followed by an \n instead: Serial.print(temperature); Serial.write('\t'); Serial.print(masse); Serial.write('\t'); Serial.print(humidite); Serial.write('\t'); Serial.print(comptage); Serial.write('\t'); Serial.println(son); // implies '\n' At the Pro…

Using two different readStringUntil "characters"

Now that it seems all’s been sorted out, how about some optimization? The range [-10 to 10] is so small (5-bit) that it comfortably fits in a byte (8-bit). So, rather than send those 2 small values as TSV, w/ lotsa extra separator characters, we can simply send 2 bytes only using Serial.write(): https://www.Arduino.cc/reference/en/language/functions/communication/serial/write/ We just need to create a char array of length = 2: signed char xy[2]; #define BAUDS 115200 #define DELAY 10 #define…
