你好,Erwan,
是的,请任何例子将不胜感激。 SPC564B74。
我正在使用DMA通道28(首先不使用生成的代码)。 eMIOS0 ch1对应于DMA_MUX通道18。
我可以通过软件请求DMA传输(设置SPC5_EDMA.SSBR = 28)。但是当我在eMIOS CCR中设置DMA位时,不再产生中断,逻辑,但没有引发DMA请求...(传输中断的DMA端未被调用,目标地址仍为空,HRSL.HRS28为0 ...)。

Hello Erwan,
yes please, any example would be appreciated. SPC564B74.
I'm using DMA channel 28 (first not used by generated code). eMIOS0 ch1 corresponds to DMA_MUX channel 18.
I'm able to request a DMA transfer by the software (setting SPC5_EDMA.SSBR = 28). But when I set DMA bit in eMIOS CCR, the interrupt is not generated anymore, logic, but no DMA request is raised... (the DMA end of transfer interrupt is not called, the destination address is still empty and HRSL.HRS28 is 0...).
