KL82 | how to config the SPI Clock

shai_b — Sun, 12 Jun 2022 10:54:39 GMT

Dear team,

My customer is using KL82 in his project and he tried to configure the SPI to run at a higher speed than the pre-made example code of the dspi polling b2b transfer master.

Could you please advise on how to config the SPI clock in prop[er way (the "ConfigTool" is not fully supported in this chipset)?

Wating for your kind feedback, Thanks a lot

BR,

Shai

Hi @shai_b

Please accept my apologies for the delay on the response. I got sick suddenly and my backlog increased. I really appreciate your patience.

I almost reach the proper way to configure SPI at a higher speed on the Kinetis L82, but I have a question, how much baud rate speed your customer need? And also, how much size of data your customer want to send on each SPI transfer? Because that info is missing to me to can have the full code working at a higher speed.

Hope you are well and sorry again for late reply, please let me know any update or if you have more questions.

Thank you in advance.
Sincerely,
Pablo Avalos.
