One of the things I did with picoCore was to reduce interrupt latency and minimize the time spent in interrupts: less time in interrupts means more cycles available for user...

Adding parity support is not difficult to add, but it is difficult to do in a simple and efficient way that does not add overhead to the code when parity...

Earlier today I hooked my scope up and found the rise time to 3V is nearly 10us with my module. It has 10k pullups. The datasheet example circuit has 100pF...

@sleemanj libusbK did the trick for me on Win 7E/64. And my avrdude 6.1/mingW build continues to work fine as it did before. I'm using a LCSoft model with the...

> Hi Ralph, is it feasible to add a new startup file e.g. "startup_hk32f030mf4p6_compact.s"? Then user can choose different options in Makefile for compiling. I suppose, but what would be...

That's a reasonable choice to make for someone who doesn't have as much confidence in my code as I do. On Wed, Jan 4, 2023 at 8:45 AM IOsetting ***@***.***>...

It was a unit I installed for a family member. I recently swapped out a head unit control board on a unit from 2019, and noticed it has an unused...

I don't think so. I think the old units have the connector populated, as there's an unused cable similar to the one for the temperature & power display. The board...

You are right about the TO-220. I just checked and it's a 7805. If I can find the 5V rail on any of the connectors, then it should be easy...
