A simple driver created for the SSD1351 OLED 1.5 inch rgb screen for the Pi Pico W
Critical fixes to come:
- Spi bindings are currently hardcoded. when migrating rp2040_hal versions, DynPinID broke and have not found a nice fix yet.
Basic usage example:
#[global_allocator]
static HEAP: Heap = Heap::empty();
const FONT: FONT11X18 = FONT11X18 {
width: 11,
height: 18,
};
...
{
use core::mem::MaybeUninit;
const HEAP_SIZE: usize = 32768;
static mut HEAP_MEM: [MaybeUninit<u8>; HEAP_SIZE] = [MaybeUninit::uninit(); HEAP_SIZE];
unsafe { HEAP.init(HEAP_MEM.as_ptr() as usize, HEAP_SIZE) }
}
