I have found on the internet a schematic of a nice LAN cable tester, using a PIC 16c54 , for which I downloaded the source code.
Since I know nothing about PIC assembly, can anybody tell me if I can substitute the 16c54 with another pic that can be programmed by the JDM?
The only 16c54 programmer i found is Tait’s parallel one that is not so simple to build…
I cannot recomment to burn a PICxx-C-xxx device with a low-cost programmer, because such devices are One-Time-Programmable (OTP). You will lost the chip (->garbage) if programming fails (due to a wiring error…) .
Replacement: I’m not sure, but possibly this chip is compatible to PIC16F628 - but some programming skills are required to migrate the code
