How to sync two dma channels with two timers

Hello Tankist,

Yes, it is possible for two timers to generate DMA request for two different events. You just need to make sure that the timer DMA request are not on the same UDMA channel.

For the the channel assignment you can refer to the data sheet chapter on UDMA, where there is a channel assignment table in the functional description section.

How to bind a timer event to a specific DMA channel? I use the function TimerControlTrigger (TIMER0_BASE, TIMER_B, true) for synchronization, but it does not contain a link to a specific DMA channel. I have two DMA channels and they work at different rates.

Sue, thanks a lot. But I didn't find the TimerDMAEventSet() function in the TivaWare Peripheral Driver Library. Where did you get it from?

Hi Tankist,

It is in the timer.c file.  Please make sure you are using the latest version of TivaWare.  We just posted release 2.1. You can get it here.

Thanks, I just really used an old version of TivaWare.
