Hello community,I'm looking for some direction on how to setup the OSPI bus to communitcate with an external PSRAM part from ISSI - IS66WVO8M8 (datasheet attached). I've read through application notes and a handful of example projects but am having a...

Hello community! Going to say thanks in advance for your help and direction here. Before I get started, understand that I am using an external rotary encoder knob as the user input for the display, no touchscreen. I am hijacking the button pressed/re...

In my attached code I am performing a read operation in lines 46 to 78. The goal is to read the ID register, should be a 16-bit value with data encoded into it representing the number of rows and columns in the part. Should be something like 0x2883 o...

Awesome. This is what I was looking for. Thanks for your suggestions. Can you clarify two things: Take 100 readings and divide by 100, gives you 10x less noise i.e. ~3 more clean bitsWouldn't this be the same as running the internal oversampler? Mayb...

Thanks for your reply and suggestions. you want best resolution , the H735 has 16 bit ADCs , but you use the 12 bit ADC --- why this?I'm using the dev kit initially which does not have ADC1/2 on all of the Arduino header expansion pins. Where I am u...

Awesome. Thanks for the invalid bitmap value. I'll add that in.I was able to fix the issue with the button invalidate function not working (bug in my code, passing the button to a function by value instead of by reference). No problems here anymore.A...

@JTP1Thanks for your suggestion! This is working perfectly! I'm a little concerned by setting the bitmap inactive bitmap index to 0xFFFF (or just forcing it to a non-valid image) because I would think passing an invalid parameter could eventually be ...
