UART connections #28

Closed prerna-khanna closed 2 years ago

prerna-khanna commented 2 years ago

Hi,

I see that the block diagram of the cube shows that the audio and video boards are connected to each other via UART. Is there any minimalistic example for UART communication between the boards? Also, where can I find more about which UART pins are connected?

Thanks.

Hi, The diagram is probably misleading, They are not connected to each other to communicate. Their debug UARTs are connected to a switch controlled by the host to select which one to be used to display debug messages. There is a simple example of TX/RX between two UARTs here though: https://github.com/MaximIntegratedAI/MAX78000_SDK/tree/master/Examples/MAX78000/UART

For the schematics, check the Hardware Development section for different boards: https://www.maximintegrated.com/en/products/microcontrollers/MAX78000.html
