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

Postby orbitcoms » Sat May 01, 2021 2:51 am

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 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?
