How to get ADC/DMA working with LWIP TCP echo example project

BMan.1

‎2022-01-10 01:41 AM

I’m working with a NUCLEO-H723ZG

I can generate a cube project with the ADC & DMA features working the way I want them to, but when I import the necessary code snippets into the LWIP TCP echo demo project & run on the same hardware the DMA fails on the first IRQ with a transmit error.

looking over the registers in the debugger both ADC & DMA seem to have the right contents regarding configuration.

any idea why the DMA would encounter a transmit error?

anyone with any experience of adding stuff to the LWIP tcp echo project?
