ATmega32: UART and SPI

[yuffiezdincht]

Salaam to all.

I have a project concerning ATmega32 where i need to take my input by SPI and pass it to a WiFi module through UART. My problem is that i dont know where to begin. Ive been searching for sometime now, but i cant find a similar topic on this. Can someone help me on this?
Your advice is pretty much appreciated! :wink:

Hi,

My problem is that i dont know where to begin

Just start with the UART
* There are countless codes and threads in the internet, in this forum and even in the datasheet.
* decide what baudrate to use and what protocol setup you need
* then use one of the code, and manipulate it to transmit "Hello world".
* now try to receive it.
* Read your WiFi datasheet how to setup.

If you don´t receive it, then use a scope and check signals (TxD from microcontroller to Wifi)
If have problems with the signals, then show us the scope pictures and a detailed description.

Hope this helps
