Hi,
I am using the uVGA library with a Teensy 3.6, and all worked fine with the default settings. But for port-related reasons, instantiating the uVGA object using (hsync_ftm_num, hsync_ftm_channel_num) = (3,4) as described in the README suits my requirements better, but I can't get it to work.
Specifically I want HSYNC on pin 34 (which should be set from the parameters above) and VSYNC on pin 35 which is just specified as a parameter to the constructor. Both signals then go through 82R resistors to the appropriate pins of a VGA connector in the normal way, and remember this is working for the default settings.
Measuring the output I can see what looks like a valid HSYNC signal on pin 34, but there's nothing on pin 35.
The constructor call I am using is:
uVGA(0, 0, 0, 3, 4, 6, 35)
Have I missed something obvious? I have checked and I don't think there is any problem with the connection of the pin, and I have also tried with (3,6) and pin 37, but also couldn't get a VSYNC output.
I'd be very grateful for any pointers or suggestions.
Thanks,
Ken
