Example Code for UNIHIKER K10&M10 - Retrieve DS18B20 temperature sensor data

Hardware Preparation

If Using UNIHIKER K10

• UNIHIKER K10 * 1
• Multi Function Expansion Board for UNIHIKER * 1 (Both “For the UNIHIKER K10-Only” and “For the UNIHIKER K10 & M10” are supported, but “For the UNIHIKER K10 & M10” is recommended, as it allows for easier program uploading and debugging even when using only the K10)

If Using UNIHIKER M10

• UNIHIKER M10 * 1
• Multi Function Expansion Board for UNIHIKER * 1 (Only the “For the UNIHIKER K10 & M10” option is supported)

Note: The multi-functional expansion board requires separate power supply when IN use. It can be powered by installing an 18650 battery or from the USB IN of the expansion board, and the PWR power supply switch needs to be turned on.

#include "unihiker_k10.h"
#include "DFRobot_UnihikerExpansion.h"
DFRobot_UnihikerExpansion_I2C eunihiker(&Wire);
UNIHIKER_K10 k10;
uint8_t screen_dir=2;

void setup() {
  k10.begin();
  while(!eunihiker.begin()){
    Serial.println("NO Deivces !");
    delay(1000);
  } Serial.println("Device connected !");
  eunihiker.setMode(eC0, eDS18B20);
  k10.initScreen(screen_dir);
  k10.creatCanvas();
}
void loop() {
  k10.canvas->canvasText("18B20 Temp:", 1, 0x0000FF);
  k10.canvas->canvasText((eunihiker.get18b20Value(eC0)), 2, 0x0000FF);
  k10.canvas->updateCanvas();
}
