Re: I2S-parallel example: Drive a 64x32 display

The link you quoted is to a commit in my project code repository, so you're close. This is the full project code: https://github.com/pixelmatix/SmartMatrix/tree/teensylc Hi EC, A silly question from me.... But in order to use I2S 8bit parallel mode successfully, one needs to use an external latch /...

Re: I2S-parallel example: Drive a 64x32 display

For those that might be interested... I have turned this experimental code into an Arduino Adafruit_GFX compatible library, to allow for simple graphics and text using DMA. I have tested this with a 64x32 Matrix.

Re: I2S-parallel example: Drive a 64x32 display

Thank you for that. However, what I want to understand is how I can get this to work in a simpler example, such as the original I2S Parallel DMA example? https://github.com/pixelmatix/esp32_I2sParallelDmaLedMatrix If your commit as what are the difference, it seems on face value all that needs to ch...

Re: I2S-parallel example: Drive a 64x32 display

I got I2S Parallel working in 8-bit mode so the SmartMatrix Library can refresh the panel with I2S data stored in uint8_t instead of uint16_t, cutting the RAM needed to hold the refresh buffer in half. I made the modifications inside SmartMatrix Library and not Sprite_TM's I2S Parallel example, but...
