Crashing esp32 #63

Closed drfhaust closed 11 months ago

drfhaust commented 1 year ago

Hey I uploaded the code to an esp32 without psram. It has 2 outputs. 1 where it crashes because of a flash error and another there I disconnect the sd card and it gives this `Rebooting...

Hello. This codebase is for a specific hardware device called WVR, not just any old ESP32. It expects to find PSRAM, an eMMC module, a DAC, etc, and will definitely crash without it.

Hi, can I swap put the sd card for the emmc, they are the same pinout, also i plan on swapping out the dac with a dsp(the adau1701) does your cide have any functions to detect if it's not the pcm5102. I'm sorry if I'm being forward. I am designing a device that plays wavs in banks using 6 buttons. It also sums the wavs with a microphone and passes the signals to a recorder. I have this working using an stm32 and an atmega328 but I am trying to lower the bom, that was when I saw your awesome device. Can I ask some questions? What is the main use of the psram? Caching or for the network functions Screenshot_20230906_144227_WhatsApp

You will have to modify the code a bit to use SD card, and to use a different DAC.

SD is slower then eMMC so you will not get 18 voices of polyphony. You could get 4 or 5 possibly.

All of the real ram is used for the audio player, so the PSRAM is used for everything else, you will see ps_malloc throughout the code which is for PSRAM.

You can ask questions, but I am on vacation for the next 2 weeks and will be slow to respond. I am not familiar with that codec, and I am not sure how much my code will help you to be honest, but you are more then welcome to try!

Thanks fir the responsr. Hows your vacation going. Please Correct me if I am wrong, but since the esp32 is just the i2smaster, I was of the opinion that it would basically spit out i2s data. I was not aware there was any communication between the pcm5102 and the esp32 asides from the audio data. That was why I assumed that The adau, which basically has a configurable i2s would simply connect to that port and it would work fine

I am only 1/2 way to my destination :) I believe you are right. PCM510x has its own clock, so I do not send a clock. Other then that it's likely the same kind of i2s data.
