If you are using teensy 4 you should be able to get low latency between ADC and MIDI send by using the ADC library in an ISR, you can set it up to read 1 pin per ISR with a counter that points to an array with the pin...
I am working on a Teensy 4.1 module that is actually a sound synthesizer, but generates a visualization on ILI9341 with the excellent TGX library.
It's using the synthesizer parameters to control some of the graphics...
I just noticed a function called "_drawCircleHelper" that appears to draw quarter circles for the rounded rectangles. is there a way to use it from the sketch? It would be quite handy for what i'm doing (drawing virtual...
I don't know If you have done something like this already and I could not find it, or if it is too slow, or this is asking a bit much! but is there something like the layer blending modes in graphics programs like...
Thank you, that is the same one I found elsewhere and used for the footprint "for now" because it looked the same. I wish they would use a common reference point!
The teensy 4/ 4.1 schematics show there is a separate power pin for the ADC, and the iMXRT1060 (VDDA_ADC_3P3) which is also the voltage reference for the ADCs. documentation about it seems a bit contradictory though.

That is really good. I made a new image 128x64, for an oscilloscope overlay, and draw directly on to it with "persistence" done by drawing "transparent black" over it every frame, then blit it on to my main image buffer...
I am thinking of using this display for a project, but the page for the displays does not show a dimensional drawing for the 3.2" version, just the 2.8".
That was a big help, thanks! I got it working with t3n, single buffer for now with 50mHz SPI, its getting the same FPS as before without any TGX primitives, (36FPS which is quite acceptable, its just a 2D interface) and...
That's good to hear, thanks! A simple example set up with t3/t3n with a few 2d primitives and text using alpha blending would be a big help getting people started.
another question, can you mix tgx with ILI9341_t3(n)...
This looks really useful, I would try it with your ILI9341 t4 library, but my PCB is already set up for the t3 version and i would have to take my module apart and cut traces. will it still work with ILI9341 T3? the...
