LAUNCHXL-F28069M: The value of USER_PWM_FREQ_kHz in lab01

Genius 3095 points
Part Number: LAUNCHXL-F28069M
Other Parts Discussed in Thread: TIDA-00364

Dear team:

I want to use LAUNCHXL-F28069M and TIDA-00364 for my design. The Switching Frequencies of TIDA-00364 is up to 10 kHz, So I modified the frequency of PWM in Lab01 as below:

#define USER_PWM_FREQ_kHz                (8.0)      //(45.0)

But after I modified, The program doesn't seem to be running (It runs normally in 45KHz). PWM port has no waveform output. Even the LED doesn't blink.

1. Can I use a PWM frequency of 8kHz to driver TIDA-00364?

2. Does instaSPIN algorithm have to connect current sampling signal? If yes, there seams no current sampling circuit in TIDA-00364, Do you have current sampling circuit design for reference?

Best regards
