STM did not work?

xiexiaopeng — Wed, 12 Jul 2017 05:32:57 GMT

I have configuration the STM of s32f74 like this

STM_0.CR.R = 0x80F00000;
STM_0.CHANNEL[0].CCR.R = 0x80000000;

but I read the count ,but they always are zero.

TIME_READ[2]=STM_0.CNT.R;

where is wrong?

Hello,

if you want to set FRZ and TEN bits, you must write STM_0.CR.R = 0x00000003; Numbering in reference manual could be confusing.

If you have any other questions, please feel free to write back.

Regards,

Martin
