Hello.
Is it possible to run the module RC522 on Attiny85?
Attiny85 has 6 pins IO, and RC522- 6 pins.
The problem I have yet to actually connect.
The RC522 pinout:
1 → SPI SS/SDA
2 → SPI SCK
3 → SPI MOSI
4 → SPI MISO
7 → RST/Reset
In Attiny85 (I'm use Digispark's version) such pinout:
Pin 0 → I2C SDA, PWM
Pin 1 → PWM, LED
Pin 2 → I2C SCK, Analog 1
Pin 3 → Analog 3 (also used for USB + when USB is in use)
Pin 4 → PWM, Analog 2 (also used for USB- when USB is in use)
Pin 5 0 → Analog
It's real?
