Linux/TLC5958: Driving through Raspberry Pi GPIO

Harry Bayntun

Part Number: TLC5958

Tool/software: Linux

Hi,

I want to drive one or more TLC 5958 using raspberry pi gpio (non cascaded). I went through datasheet but found it to be too vague about software part.

1. Can anyone point me towards relevant documents and sample codes?

2. Has anyone driven this one or similar IC using user mode DMA from raspberry pi? For my application I need communication in MHz. Does anyone have any experience about it?

Thanks

Unfortunately, we have never used raspberry pi, but you can refer to the timing chart and register map in the application report.

Thanks.
