PLUME – Emiters & Serial Audio Interface

Hi everybody,

Today I worked on the Serial Audio Interface that we will use to communicate with the Audio Codec. We have to use it as an I2S Bus. However, it is not very simple because the documentation on the Internet about it is very poor. So I made my own configuration, I’m ready to use it. Moreover, this option (SAI) is only available on the STM32f2xx. I’m currently waiting to receive our receiver board to check my code and my configuration.

Moreover, I worked on the emitters and specifically on the emitters coils. We have to made them by ourself, and it’s not a very funny work. I just finished now and we have 3 perfect emitters coils of 700 uH each. 😛 We will use it tomorrow.

I have some pictures for you… 🙂
