Re: Pimoroni Trackball breakout (PIM447)

Finally, springton hat work fine. I don't know what happened when I tested it...
It's perfect with the pyb405 which has real interest. For example, I use it with epaper (for raspberry) and the trackball for command display text... Beautifull and perfectly convinient.

Thanks.

Re: Drive WaveShare 2.7 inch e-Paper

Ok, so It seems that the problem come from the spi command on esp32 implicate a mosi and miso pins, althoug there is only a din pin on your epaper. So for me, you could try this: sck = Pin(0) miso = Pin(4) mosi = Pin(2) dc = Pin(25) cs = Pin(5) rst = Pin(18) busy = Pin(19) spi = SPI(baudrate=2000000...

Re: VS1053b audio drivers: play music, speech or sound FX

yep, The audioskin use i2C, no pin for headphone. I tried the pin "X22" without success for microphone. So, it looks impossible to adapt audioskin to VS1053... I tried 200 secondes of duration, and everything is right. So no limitation of time... Wonderfull! The noise is a little bit problematic for...

Re: Drive WaveShare 2.7 inch e-Paper

You have to add afetr the line e.init(): w = 400 >>> h = 300 >>> x = 0 >>> y = 0 >>> import framebuf >>> buf = bytearray(w * h // 8) >>> fb = framebuf.FrameBuffer(buf, w, h, framebuf.MONO_HLSB) >>> black = 0 >>> white = 1 >>> fb.fill(white) >>> e.display_frame(buf) And for sure change the value of w...

The trackball is nice.

Re: VS1053b audio drivers: play music, speech or sound FX

Thanks Peter for your help...again. So, I have used an other code and effectively it works... You have right, I have used the calling code for flac sound and it's why it didn't work. Just, there is a confusion between sdcs and xcs on Y3 or Y4 pin in the simple code on the first presentation page, an...

Re: Pimoroni Trackball breakout (PIM447)

Yep,
Finally it works with pyb26.

I don't know why it doesn't works with my pyb405, maybe cause by the prototype "Springton hat" ...

Otherwise this trackball is good.
The sensibility is very fine and you can adjust easly add a lots of button's commands.

Thanks.
