Hello to all,
I got the board recently and have tested the modules with the code in the Typical used, now I have 2 problems:
1. I used the Processor Expert to generate a PWM signal with 400ms period and 100 starting pulse width, then I checked the signal by a oscilloscope ,I found the period was 360ms and there's always 16% error with the period and the duty time after I use the SetDutyMS(). And the method SetRatio16() seems don't work at all, the ratio was always <1% regardless the number I set. Same situation after changed the FTM.
int main(void)
{
LDD_TError Error;
LDD_TDeviceData *MyPWMPtr;
unsigned int i,j;
PE_low_level_init();
/* Write your code here */
MyPWMPtr=PWM1_Init((LDD_TUserData *)NULL);
for(i = 0; i < 65535; ++i) {
Error=PWM1_SetRatio16(MyPWMPtr,i);
//PWM1_SetRatio16();
for(j = 0; j < 65535; ++j);}
...
}
2. The CAN module can't generate any signal to the pins: I used the looping mode for testing, the receiver can receive the frames sent by it self in the debug mode , but there is no signal detected on the CAN_H or CAN_L.
Thanks very much for the help !!
