Thanks so much for posting the update on this thread! I had the exact same issue.
Sure enough my crystal load capacitors were marginal after changing the board stack-up, increased them slightly and I can now connect to all my access points!
Thanks again, been trying to figure this out for days!

Thanks for the maximum ratings I'll keep trying to improve my driver, but it looks like I'll have to use a bigger buffer and intermittently transmit data for now.

I have a few questions about EOF interrupts:

Does out_eof_des_addr register contain the address of the descriptor that just finished ...

Putting the CPU clock speed to 240 MHz has allowed me to output at 6.66 MHz when using two 2048 Byte buffers.

I haven't been able to try a buffer size above 4092 because of the crash error stated in my last post. I've isolated the issue down to a bad address being returned from the queue and stored ...

I've now made the program load the address of available buffers into a queue, I've used a 3 position queue as I have 4 buffers.
The program works at 4 MHz when each buffer is only 2048 Bytes, but when each buffer is 4092 Bytes at 4 MHz it begins to glitch. Anything above 4 MHz begins to glitch ...

I've used your printercart_simple example as a starting point for the i2s parallel driver. For my case I need to output at 10 MHz I've managed to reach this speed using a single buffer and no EOF interrupts, but I'd like to implement continuous transmission. I now have a circular DMA link with 4 ...

Yes it looks like a bad version of libesphttpd is being referenced.

I'm quite new to the esp-idf and having trouble getting the "check_waveform" code to run correctly. I cloned it with git clone --recurse-submodules -j8 http://git.spritesserver.nl/printcart.git/ then compiled with make flash, but an error came up about a line containing only >>>>>>HEAD in the ...

I've managed to find your waveform generator such a neat little tool thanks! How did you go about outputting the hex data on the ESP32 during testing?

I'm looking over the printer cartridge driver that Sprite_tm has written, its a great starting point thanks! Have you released the code for the HTML5 web interface to modify the signals in real time? I just saw it on your have a Hackaday video :D

Heres what I've got so far (I'll change it now I've ...

Hello,

I'm using the I2S driver to output in 16-bit parallel mode with two buffer to allow nonstop transmission, my aim is to use the I2S_OUT_DONE_INT_RAW interrupt to call a function which updates the buffer that has just been output via DMA, meanwhile the second buffer will be output via dma ...
