TLC5971: Linux drivers or software library

Part Number: TLC5971
Other Parts Discussed in Thread: TLC5973,

Do you have Linux drivers or software library for TLC5971 and TLC5973 PWM drivers? Our software team is working on this.

Hi Laura,

I am sorry we have no such kind material in the hand.

Any more support needed please let me know.

Thanks!

Summer

Do you have example fw or sw drivers, preferably Linux but we can make do with even examples of code for another system.

We are working to create a Linux driver (in c language) for your LED PWM drivers (TLC5971 initially and TLC5973 for the next re of our PCBA).

As an additional note: our HW design is controlling the TLC597X serial clock and serial data inputs via general purpose I/O (GPIO) from our main processor.

A Linux driver or firmware code that uses GPIO to drive these inputs would be best for us.

Hi, Laura,

We have C code using GPIO to drive TLC5971, but it's not in Linux.

We use MSP432 launch pad to develop the code in CCS environment.

You can refer to the code here:

Thanks.
