Other Parts Discussed in Thread: HALCOGEN

Hi Sir,

I enabled spi2 driver in HALCOGEN and in spi2port, i have selected SCS[1] pin mode as GIO, as shown below:

i have connected SPI2- CS1 pin to picoscope on the micro controller for checking its status. while debugging the code the status of the pin is not changing.

6866.3-7-CS.zip

i am attaching the code kindly check it and please let me know if any correction needed.

Thanks and Regards,

Hello,

Please, check SPI2 in HALCoGen-->PINMUX tab. Also clear the conflict.

Best regards,

Hi Miro,

Thanks for your reply.

I did PINMUX changes. still it is not working .

I want to do it for SPI1 also. Should i have to select pinmux for SPI1 also?

Regards,

Gargi
