Hi! I am using FRM ke16z and I am generating with FTM PWM. I see on the oscilloscope the amplitude of the signal is 0.5 V . It seems to me pretty low. I need for controlling some ESC a pwm between 0 and 5V. What can I do?
TY!
Hi,
Thank you so much for your interest in our products and for using our community.
I am testing the example frdmke16z_ftm_pwm_twochannel (SDK version 2.13.0) and probing the signal using an oscilloscope on LEDRGB_BLUE, it does output the PWM as expected
Maybe the reason you don't see the signal on the arduino pinout is that R9 is not populated by default.
Hope it helps you.
Have a nice day!
I see the signal but it has the amplitude of 0.5 V when is 1 and 0v when is 0. What do you mean with that R9. TY! @_Leo_
I mean resistor R9 that can be seen in the image that I attached. I consider that it is recommended that you try the example I mentioned above with another board, because I cannot reproduce your problem.
I dont get it with that R9. I should place a resistor? I give you code, it very simple.
And in main i just call the init and after that, in while(1) i call the board_updatePWM1. TY! @_Leo_
