CC1310: SPI pins individually controlled

Galaxy Yue

Part Number: CC1310

Hi Team,

The frequency of my SPI is 4M.

I want to control the SCLK pin alone to output 65 clock cycle signals of 31.25Khz when the SPI is not working.

But now the SCLK pin is initialized in PIN_INIT.

1.How should I control the SCLK pin to output clock signal?

2.Because SCLK is already initializing PIN_INIT and there is no feedback handle, how should I release this pin?

Best Regards,

Hi Team,

It's my solution for customer.

1. Make sure the SPI module has stopped working and the SCLK pin has been released.

2. Configure the SCLK pin to GPIO mode to facilitate manual control of the pin output.

3. Based on your desired clock frequency, calculate the time interval for each clock cycle.

4. Control the output of the SCLK pin through code.

I'm not sure it's suitable or not.

So he said that he didn't know how to release the SCLK pin.

If you can solve the first problem,I think you can ignore the second,because the first is the original problem.

Thanks for your support!

Hi Galaxy,

Your solution is correct. But for your first issue, you have to use the PIN_remove() method to deallocate that particular pin.

Hi Arthur，

The PIN_remove() is just a function or a website?

I open your " the PIN_remove() ’' but It shows "Page Not Found".
