It looks like it rounds down before reaching a modulo. 150Mhz / 2288.88 hz = 65534.235 which is greater than 65534 but equal to when the decimal point is thrown away. I haven't tried 2288.85 yet to see what the LED...
I've been looking into this yesterday too. In the examples menu there are options that show all the wake up modes. I'm just going to try the code and see what happens.
Replying to myself again...a quarter of that heatsink is likely lower than 36 C/W, maybe 30 or high 20's because all 4 sides are exposed to fresh air. I'll see if I can find a commercial product that fits...

This 1.1" x 1.1" x 0.6" heat sink appears to...
I was wondering if these calcs are accurate:
3.3V * 100mA (@600Mhz) = 0.33 Watts of heat
Junction-to-Ambient, no heat sink, natural convection: 40.8 C/W
0.33 W * 40.8 C/W = 13.5 C temperature difference
max...
It looks like pin 13 will do 16 bits on the lowest PWM numbers (where it matters) at 2289 Hz but not 2288.82 Hz. Here's code that changes the brightness by typing values into the serial monitor. I was using this on...
This all looks complicated and requiring knowledge of interrupts and low-level coding. Is there a simple way to do PWM like AnalogWrite? I'm just trying to do 16,17, or 18-bit dimming of LED's. The default max of...
Thanks, it looks like I might be able to use the TeensyTimerTool library for GPT. Low-level coding is beyond my knowledge level.
With some testing today it appears that both quad and flex are set to 15 bits. The...
Is it possible to get a few more bits by modifying the file pwm.c or writing a new function? With my basic understanding, it seems that the quad timers are limited to 16 bits and flex timers limited to 15 bits with the...
It's unclear yet whether the main module number has to match up, but it sure looks like the submodule does not need to. I don't have an oscilloscope, but I can measure the temperatures of the MOSFET's and watch the LED...
After reading about this for hours and doing some testing, it appears that MOSFET's can run parallel as long as duty cycle is the same and the same type of timer channel is used:
all Flex A in parallel,
all Flex B in...
