Hi,
Can you please clarify what exactly do you mean by "entcode a pwm signal of 300 khz".
Did you mean you want to generate 300KHz PWM signal?
There are examples available for PWM generation on F280049C.
You can refer to examples under
C:\ti\c2000\C2000Ware_2_00_00_02\driverlib\f28004x\examples\epwm
for calculating the PWM frequency, please refer to TRM
chapter 18.4.3 Calculating PWM Period and Frequency.
Hi,
I am a beginner in DSP C2000 F280049C, and I wanted a simple code for pwm with 300khz
Hi,
Then the example I provided above is the right place for you to start. Good luck!
Hi Subrahmanya,
Thank you. I am working on the isolated half bridge converter. To generate the PWM signals for the MOSFETs, i need to use phase shift modulation. can you help me with coding about how to generate a phase schifted PWM signals with 180 degree.
Thank you in advance
Hi,
There are more examples available at C:\ti\c2000\C2000Ware_2_00_00_02\driverlib\f2837xd\examples\cpu1\epwm
You can refer to these examples and port them to your target device.
epwm_ex3_synchronization should specifically address the phase shift related configuration you are looking for.
Hi,
Thank you so much. I have implement my PWM Signal at 400khz what I need mostly is to make each cycle of this pwm have a different duty cycle, i have to use a Timer to generate interrupt every 400khz frequency and in the ISR change the PWM duty cycle. have you any idea about this ?
best regards
Hi,
TImer inside PWM module can generate interrupts. Some of the above mentioned examples also have interrupts enabled.
Let me know if you still are having trouble generating interrupts after going through the examples and documentation.
