Hi I have recently purchased the LJTick-DigitalOut5V so that I can achieve a 5V PWM straight from the T7 device. My problem will seem quite vague but I'm hoping for any information you can give me.
I am having trouble using the 5V PWM to power my device. The device itself is a electromagnetic brake which requires a 5V PWM signal to get the full range of output voltages. I have used the normal 3.3V DIO to power the brake fine only it isn't able to achieve the maximum braking, hence why I bought the LJTick-DigitalOut5V. I used the exact same 50Hz PWM but when I try to control the voltage output the slightest change from minimum PWM output results in near maximum voltage output to the brake.
Does the LJTick device do anything else, apart from increasing the logic level, to the signal I am outputting?
Thanks,
Stuart.

I can't think of anything extra. The LJTDO5V is pretty simple. Do you have a scope you could use to look at the working 3.3V signal and non-working 5V signal (with all the same PWM settings)? Or you could feed the signal back to an analog input and use LJStreamM to look at it.
Hi I have since fixed my problem, I was reading my required PWM frequency incorrectly and so it was causing problems.
Thanks though.
