| + | ==== The Wiring ==== | ||
| + | \\ | ||
| + | The wiring for the Zero is exactly the same as for the Pico, unfortunately there are two slight differences. | ||
| + | |||
| + | * 1. The GPIO Pins are different. | ||
| + | * 2. The Pico uses SPI1 and the Zero uses SPI0 | ||
| + | |||
| + | See the wiring below: | ||

| + | Once you have wired up your LCD, we can move on to the software. | ||

| + | ==== The Driver ==== | ||
| + | \\ | ||
| + | You can download the driver here: {{ : | ||

| + | \\ | ||
| + | I am not going to talk about the driver because there isn't anything in there we need to change. | ||
| + | \\ | ||
| + | \\ | ||
| + | ---- | ||
| + | ==== Test Code ==== | ||
| + | \\ | ||
| + | All this test code does is to print 8 lines of text with sequential numbers after them, the numbers keep incrementing one at a time. The test code is designed to ensure the LCD is working fine, not to provide any real functionality, | ||
