I need a little help here.
I use a UART component in a PSoC4 project and I would like to save incoming bytes to RAM without CPU intervention.
I do not know what I am missing but it does not work to me.
I attach a simple example of using DMA and UART RX facing my issue. It can run directly in the Pioneer kit.
The examples for DMA and UART RX use the SCB blocks, which is not an option for my application since the SCBs are reserved for other serial communication blocks. My only option is the UDB UART mode but IU cannot make it work.
Thank you very much in advance.
Solved! Go to Solution.
I tried the modification you suggested and it worked.
I also found why the callback was not called and then I applied the corrections to the rest of the project.
