Qwiic System

Hello,

I am making a sonorous effect toy. I have a bunch of sensors

In the datasheet of the WT2003S chip, there is a function for specified play mode, I want to use play in a loop without having to be pooling for detecting when the song has finished playing. this feature’s not implemented in the firmware 1.1. I would like to add that feature to a custom firmware. but that generates a question.

How to upload a firmware?

This is not something we have a tutorial for unfortunately. There’s a 6 pin (2x3) header on the board for uploading firmware and you will need a AVR programmer and some software to flash the firmware but sadly we’re not able to assist with how to do that.
