So I have a need to override a pushbutton (from ON to OFF) and came up with this concept; a solenoid piggyback on a pushbutton switch with a 3D printed cap held by a strand of wire.

The sending device has the typical 18F4550 USB setup and it is set to "Define OSC 48". The receiving device is set to "DEFINE OSC 16".

There is probably a little bit of both. I did a search in the forum, but couldn't find anyone having the same issue.
rsocor01 - 23rd April 2024, 23:22By lowering the baud rate you're now allowing device B (and SERIN2) twice the time to receive the bits and assemble the byte.
That's probably what's helping a lot more than any line noise issue.

Tumbleweed, I had very strong suspicions that the issues were in the communication lines. I changed the Baud rate from 19200 to 9600 and I haven't got anymore wrong data at the receiver. I remember...
rsocor01 - 22nd April 2024, 22:35Ioannis, yes I'm doing data validation checks all the time. The first byte of the array is always 174. If this condition is not met, then the reading is discarded.
rsocor01 - 22nd April 2024, 22:26Just to correct myself in #9...
At 19200 baud each bit should be 52us +/-1.5us, give or take (about 3%).
I was thinking byte times, not bit times.
As Richard noted, the problem could be in any other part of your code. So you are alone on this as we cannot guess what may be happening there.
However, the part you posted does not somehow checks...
Re: New project - MSFS C++ USB interface
Hall effect switch with small magnet or if there is magnetic field around solenoid coil that the hall effect device can sense
