I2S pinouts don't match other boards #60
Description
The standard VGA demo board (https://shop.pimoroni.com/products/pimoroni-pico-vga-demo-base) uses:
| Signal | Pin | GPIO |
|---|---|---|
| LRCLK | Pin 34 | GPIO28 |
| BCLK | Pin 32 | GPIO27 |
| DAT | Pin 31 | GPIO26 |
These docs from Arduino (https://arduino-pico.readthedocs.io/en/stable/i2s.html) note that LRCLK must always be BCLK + 1.
Currently we have:
| Signal | Pin | GPIO |
|---|---|---|
| BCLK | Pin 34 | GPIO28 |
| LRCLK | Pin 32 | GPIO27 |
| ADC_DAT | Pin 31 | GPIO26 |
| DAC_DAT | Pin 29 | GPIO22 |
