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,

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

Re: AD75019 16x16 crosspoint switch/multiplexer cannot communicate via SPI
I got it directly from AD, so I doubt it's a knock-off. I had 2 chips, both performed the same, but I burnt out one of them (and a pyboard at the same time) by mis-connecting the 12v power supply. I agree, it seems incredible that AD would sell an expensive chip like this ($20/each) for 20 years wit...

Re: AD75019 16x16 crosspoint switch/multiplexer cannot communicate via SPI
@pythoncoder: Thanks for the tip. I have stopped using the multimeter and instead inject a 500Hz sine wave on one of the pins and have an oscilloscope connected to the other. The signal generator and scope share the analog ground from the analog power supply. In the meantime, I have done extensive t...

Re: AD75019 16x16 crosspoint switch/multiplexer cannot communicate via SPI
Thanks!
I have added diodes to the cirucuit as suggested in the data sheet. I used 1N4004 diodes instead of 1N4001 or 1N5818 as suggested, no change. I also tired BAT46 diodes, but no change either...
I am really at a loss..
Thanks for the help in any case!

Re: AD75019 16x16 crosspoint switch/multiplexer cannot communicate via SPI
@pythoncoder Yes, all the timing requirements are met and I have measured on the scope. I've continued to test this, now using a signal generator and the behaviors is exactly as I said: With analog supplies +/-7.6v normal correct behavior With analog supplies +/- 9v or +/- 11.35v or +/-12v, once som...
