亲爱的各位，我们面临着正确配置DMA的困难。请在下面找到DMA的目标：TopDead有4个StaseReg，DMA会在SCORTEM4的SRAM上复制StaseReg到TMP值。对于每个溢出，我们需要传输4状态Reg：因此TDS（描述符X）必须链接在一起。当4状态寄存器传输到“TMP”时，DMA必须生成一个TIG。这个TIG稍后将被另一个DMA使用，但是目前我们关注的是第一个DMA配置。在过去，我们用PSoC5LP做了相同的流程，我们尝试用PSoC6来执行同样的流程。你的，罗宾。D.CyWrk.CaseV01.Zip7.1兆字节 以上来自于百度翻译 以下为原文Dear all,We are face to difficulties to configure correctly the DMA. Please find below the goal of DMA :The topDesign have 4 statusReg, the DMA will copy the statusReg to a tmp value on the SRAM of CortexM4.For each overflow, we want transfer the 4 status reg: so TDs (descriptor_X) must chained together.The DMA must generate a trig when the 4 status reg are transferred into "Tmp".This trig will be use later by an other DMA, but currently we are focus on the first DMA configuration. We have done the same flow with a PSoC5LP in the past, we try to perform the same with PSoC6.Yours,Robin. DMA.cywrk.Archive01.zip 7.1 MB
