Modified from byrek/arduino-cj125 I moved the library files into the main dir to make it more easy to source control and develop my project.
- SPI
- PID_v1 (arduino --install-library "PID:1.2.0")
arduino --board arduino:avr:leonardo --verify ./arduino_cj125.ino or ./verify
| Arduino line | Shield |
|---|---|
| RESET | CJ125 Reset line |
| 5V | 5V |
| GND | GND |
| VIN | When JP1 is closed, the arduino is supplied with +/- BAT terminals |
| Analog in 0 | CJ125 UA |
| Analog in 1 | CJ125 UR |
| Analog in 2 | Battery voltage monitoring |
| 4 | Analog output option (might be used to deliver O2 narrow band signal, not implemented in code) |
| 5 | PWM output for LSU heater |
| 10 | SPI CJ125 Chip select line (NSS) |
| 11 | SPI MOSI |
| 12 | SPI MISO |
| 13 | SPI CLK |
