I know this post was from 2022, but it brought back memories of that holiday season. Our family also chose to stay home for Christmas due to the weather. We had planned a trip to France through [mod edit: link to advertising removed] but decided to postpone it until conditions improved. In the...
Hey Martaine2005,
You can post code here by wrapping it in code tags. Just type before your code and after it, that will format it properly so it’s easier to read.
For example:
int main() {
return 0;
}
That should display it in a clean, readable box once you post.
Hey kupinth,
That SOT-26 with the “B27” code could be a dual transistor or voltage regulator, depending on its spot in the circuit. If it’s near the optocoupler or PWM chip, it’s likely part of the regulation stage. Try tracing its pins and share a clearer photo of that PCB area, it’ll help...
You can bypass the remote receiver by powering the LED driver directly. From the photo, the IR module connects to the control chip, disconnect it and bridge the signal line so it stays “on.” Just double-check the traces and voltage with a multimeter before making changes to avoid shorting anything.
It looks like your mechanism is working since the LED lights up when the split passes. The issue might be with the TMCM-1290 homing setup or sensor input configuration. I’d check the board’s input settings and maybe monitor the sensor signal directly to see if the board detects it. What homing...
Hey LukeKai,
That MOSFET’s a bit hard to ID from the photo. Try cleaning it or checking under magnification, there might be extra markings or a logo. If you share the full code and what device it came from, it’ll be easier to find a match.
