Compiler/TLC5957: Can i configure the SPI plus DMA to write the bit banging avoiding to use all the CPU only for the display?

Part Number: TLC5957

Tool/software: TI C/C++ Compiler

Can i configure the SPI plus DMA to write the bit banging avoiding to use all the CPU only for the display?

In this way i can use the system not only for the display but also for other activity!

With the DMA i don't have to use the CPU.

Can I use the SPI master mode in this way and feed it with the DMA?

Best regards, Alberto

    Hi Alberto,

    It is me again... I have consult all experts in our team and no one have develop experience with DMA before, neither this device or other display driver. Actually it is our first time heard about DMA control. Usually we would only develop a example sample of MCU with C code. Sorry that we could not provide help for your request. What I suggest is you could consult your CPU and DMA vendor.
