Broken Example Code for Eink FeatherWing #11

Closed djecken closed 5 years ago

djecken commented 5 years ago

Testing bitmap demo code with PID 4128 2.13in eInk Tri-Color FeatherWing and Feather M4 Express.

Got the following error message in Mu serial console.

File "code.py", line 22, in <module> TypeError: unexpected keyword argument 'sramcs_pin'

Pins were changed to reflect featherWing. Tested using Feather M4 Express.

# create the spi device and pins we will need
spi = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)
ecs = digitalio.DigitalInOut(board.D10)
dc = digitalio.DigitalInOut(board.D9)
srcs = digitalio.DigitalInOut(board.D6)    # can be None to use internal memory
rst = digitalio.DigitalInOut(board.D11)    # can be None to not use this pin
busy = digitalio.DigitalInOut(board.D12)   # can be None to not use this pin

the library just got updated you can try the mpy's from this release

Updated circuit python epd library to latest. Testing the epd_blinka.py demo code and missing the "PIL" library – Not seeing that in the bundle.

oh thats for linux you cant use that with feather :)

OK. now testing the edp_bitmap.py example code with updated display/pin values.

Display doesn't update but the code shows fine in mu's serial.

code.py output: File opened Size: 66198 Image offset: 54 Header size: 40 Width: 212 Height: 104 Bit depth: 24 Image OK! Drawing...

Using these pins for display object

spi = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)
ecs = digitalio.DigitalInOut(board.D12)
dc = digitalio.DigitalInOut(board.D11)
srcs = digitalio.DigitalInOut(board.D10)
rst = digitalio.DigitalInOut(board.D5)
busy = digitalio.DigitalInOut(board.D4)

display = Adafruit_IL0373(104, 212, spi,
                          cs_pin=ecs, dc_pin=dc, sramcs_pin=srcs,
                          rst_pin=rst, busy_pin=busy)
