Is there "marketplace" for hiring ESP32 developer? Need help with ADF

[orbitcoms]

Hi,

I have some code written to play mp3 files from spiffs based on the example code in adf getting started ("play_mp3").

The developer I used got the code running so that I can play any of the mp3 files in my spiffs folder at certain volume ok.
But, there is a long delay (almost a second) between calling the function to play a file and the sound actually being produced.

Neither Espressif, the original developer or replies from a post I did, have been able to fix this.

The code is a critical part of my project and I need the delay to be around 100ms or less.

I am prepared to pay someone to either fix the code I have, or to write new code to do the function.

Usually forums have a "marketplace" where you can talk about commercial jobs, but I cannot find one here.

My hardware consists of a ESP-WROOM32 connected via I2S to the MAX98357A codec/decoder/amplifier.
Currently, the ADF setting in menuconfig selects "custom board"

The code has basic functionality:
1. Copy a folder containing mp3 files to spiffs at flash time
2. Be able to change Volume for playback (This is set during config and does not need to be adjusted on a "per file" basis)
3. Play a specific file from spiffs based on string filename, like "Play("FileX.mp3")

It needs to be 'thread safe"

Thanks

Hi, I'm willing to work on your project with you if you still need help.

Hi,

I did manage to get the adf framework running and delay sorted out.
However, I do have another job where I need someone to port "Decawave" code to ESP-IDF.

The main driver modules all are platform independent and there is a folder that contains the platform dependent modules that need modifying to work ok with ESP-IDF.
The modules contain SPI code, timer and interrupt

If I send you the code I need to port, could you take a look and give me price to port it if you are willing/able to do this?

Sure, ill take a look and if it looks like something I can do for a fair price I'll quote you.

Sure, send me the code and I'll take a look.
