Re: external interrupts on the D series board

Hi Dave! I'm back to pyboard projects. I have a load of rotary encoders to read for input and the 16 channels aren't enough.... So I'm wondering how to access some of the many interrupt channels available on the STM32F722IEK microcontroller? Please don't offer me suggestions as to how to not use rot...

external interrupts on the D series board

Hi, Can anyone please tell me the specs for using external interrupts on the D series board. In particular, when using the WBUS-DIP extension boards? I am looking for lots of interrupts, and the 16 available on the pyboard v1x are not enough. But the doc in the pyb library on class ExtInt would seem...

Re: AD75019 16x16 crosspoint switch/multiplexer cannot communicate via SPI

My project is described at various places, the idea being to be able to get all the possible combinations of audio routings from the pickups with a single click, while allowing creation of preset configs etc. and providing all sorts of cool stuff as well ;-) Ardu and Py Guitar Home page CCC Presenta...

Re: AD75019 16x16 crosspoint switch/multiplexer cannot communicate via SPI

@vidalv Hello! Yes, in the end I got it working perfectly. I have not been on the project lately following various things that have happend around me and to me, sigh. This is one of the last efforts I made with a full demo of the AD75019 working perfectly. https://youtu.be/aAYDpoLa12o But I plan to ...

Re: pinout for the Colour LCD skin LCD160CRv1.0H

Thanks for all that info!

I now realize that the LCD is out of stock but as soon as it's available I'll order one and try it out and report back!

Ciao,

I use it only with I2C, no issue at all.
Thanks for that info. Just to be sure, you use it with only SDA and SCL connected to the pyboard? not counting Power and GND which can come from anywhere, of course.

Thanks!

Re: pinout for the Colour LCD skin LCD160CRv1.0H

Hi Dave, Thanks for those pointers. If I understood well, I could just use 2 I2C pins to send to and read from the LCD, given that I provide power & GND to it from another source? Yet, when I look at the driver code, it seems to require an SPI object at instantiation as well? If that is true, how do...

pinout for the Colour LCD skin LCD160CRv1.0H

Hi, I'm considering using this LCD skin in a project but can't see what connections it needs? I won't be plugging it directly into the pyboard, but into a custom PCB. I need to know how many I/O pins this LCD will require because my application is already very I/O hungry. My other option is to use a...

Re: MicroPython Newsletter Issue 1

I'm dying for one of these for the next generation of my PyGuitar project!

Any dates set yet for availability? Alpha/Beta testing? I'm available!

Ciao,
