在社区上看到关于MibSPI的帖子,说MibSPI支持DMA,但是我在TMS570ls1224和0914的手册上看到
When the multi-buffer mode is used,the DMA enable bit in the SPIINT0 register is ignored.这句话,这句话的意思是否是SPI启用Mb模式时,就无法使用DMA?那我应该如何控制Mib模式的关闭(DMA方式的启动)?另外,当我使用EB tresos的配置工具时,我根本无法更改是否使用DMA(按下按钮没有反应),如下图请问应该如何更改SpiHardwareUnit_0使用DMA?
请您试一下下面的代码
This code requires external connection between MIBSPI1 and SPI4 (SOMI to SOMI, SIMO to SIMO, CLK to CLK and CS_0 to CS_0)
