An Pico integration to mcauser' MicroPython MAX7219 libary. This script has a method to make the text scroll inspired from Alan Wang
| The Pico does'nt have a 5v pin, but the VBUS is connected to the power input. The MAX7219 need an 5v input, so the Pico's power supply will have to be 5v. This is the default pins for SPI0. | MAX7219 | Pico Name | Pico GPIO | Pico PIN |
|---|---|---|---|---|
| VCC | VBUS | 40 | ||
| GND | GND | 38 | ||
| DIN | MOSI (SPI0 TX) | GP7 | 10 | |
| CS | SPI0 CSn | GP5 | 7 | |
| CLK | SCK | GP6 | 9 |
If you change the SPI clock pin (CS) remember to change it in code.
