Hi. I'm developing an application with ADSP-2191 which transfers data from UART port using DMA. I have a problem: I have to set the DSP to call ISR when DMA ends a transfer but I didn't find which interrupt use in documentation. What is the correct interrupt to use? A secondary problem: documentation is not clear in how to set a DMA transfer for UART. The methods used in manual don't work and I used some code taken from an example given with VDSP++ (UART.asm). Does anyone know the correct procedure? Thanks. Fabio Sebastiano |
