Hey everyone,
I'm pretty new EE in general. It's always just been a hobby after I took my physics course. I purchased the TL866A in hopes that I could tinker and learn.
Unfortunately, like Prema, every time I try to read a SOIC 8 chip in-circuit (the clip was included in my purchase), I get the over-current error. I've tried several different SOIC 8 chips in-circuit.
This time, I'm trying to clone my gate opener so I don't need to call the housing authority to register a new one.
The chip is a Microchip 12LCE519-4I SOIC 8. In the program, I selected PIC12LCE519 SOIC 8.
I also tried shorting C22 as radioman suggested, and it seems to work! But due to my inexperience, I'm not sure if it's truly working. First, there is no chip ID, but I noticed that "Read ID" function seems to be associated with the chip type? As in, some chips the option is there and some chips it's grayed out. Is that normal? Also, which I click the "Config" tab after reading the chip, it gives me a warning "The Value must less than 0x0FFF!" So I'm not sure if this is because I overrode the overcurrent protection. I know Prema just desoldered it, but I'm still "developing" my IC desoldering skills and would like to first see if it's possible to do it in-circuit.
I'll attach some screen shots after reading the chip. Can someone people look over them to see if it seems right?
Any input into my situation or just the "over-current protection" in general would be appreciated.
Thanks!!
