Pin Assignment
Requirements
- Two HAL : 2 Dig
- One Dry Pulse : 1 Digi
- Temp and Humidity : I2C
- VIn : 1 Ana + 1 Digi (trigger)
- Two Push Buttons (2 Digi)
- 4 Digital Output (4 Digi)
Total :
- I2C
- 1 Ana
- 8 Digi
- 1 Interrupt
Notes
- One interupt pin can be used to monitor multiple inputs with the helps of diodes
- Digital inputs can be extended with I2C Digital extender
- Analog inputs can be extended with ADS1515
- We can easely read 5 digital inputs on an analog input with the help of a tension divider
