Which Serial is Port.C on the M5Paper?
-
hello,
like to use the m5paper port.c to serial read a gps. cannot seem to find which serial port is port.c. Serial is USB-C port, so is it Serial1? documentation only mentions g18/g19...
thanks

answering my own question:
#include <M5EPD.h> #include <TinyGPS++.h> static const uint32_t GPSBaud = 9600; TinyGPSPlus gps; HardwareSerial ss(2); M5EPD_Canvas canvas(&M5.EPD); char latStr[10]; char lonStr[10]; char speedStr[10]; void setup() { M5.begin(); M5.EPD.SetRotation(0); M5.EPD.Clear(true); ss.begin(GPSBaud, SERIAL_8N1, 19, 18); canvas.createCanvas(960, 540); canvas.setTextSize(3); canvas.clear(); } void loop() { int b = ss.available(); while (b > 0) { gps.encode(ss.read()); double lat = gps.location.lat(); double lon = gps.location.lng(); double speed = gps.speed.kmph(); dtostrf(lat, 2, 2, latStr); dtostrf(lon, 2, 2, lonStr); dtostrf(speed, 2, 2, speedStr); canvas.clear(); canvas.drawString("Lat: " + String(latStr), 50, 100); canvas.drawString("Lon: " + String(lonStr), 50, 150); canvas.drawString("Speed: " + String(speedStr), 50, 200); canvas.pushCanvas(0, 0, UPDATE_MODE_DU4); } }
