2DAddressing

I followed this document, but the UART value is coming out as garbage. The data is being output as 8-bit, but the variable used to store it is 32-bit, so I think that's causing the issue. How can I solve this

[KDJEM.1]

Hello @dlagyals;

Why do you use "(uint32_t)&(USART1->TDR)" as a destination address in YourNodeName2 instead of "&(USART1->TDR)" like as the Github example?

Could you please try to change the destination address in YourNodeName2 to "&(USART1->TDR)"

The link‑transfer consists of a series of 32-bit single reads: up to six single reads for channel with linear‑addressing mode and up to eight single reads for channel with 2D addressing mode.

I hope this help you.

Thank you.
