Hello,
I bought two testers from Aliexpress. I tried to change the firmware on the first one in november already and posted my problems
here.
Cos I haven't so much time I bought a second one and tried to update this one. But it will also not work.
What I have:
TC1 - 644PA inside - which I already tried in november to get working. MLCCs, diodes and measurement Rs (to 0,1%) changed, U4 successfully flashed.
Tester powers on, makes
one measurement and powers off. Powers off so fast, that's not possible to read the result. As I described in my old postings. Same with v1.40
T7 - 344PA inside - HW ist china factory, no MLCCs or something else changed. U4 successfully flashed.
If there is no part in it, tester did not find any part (which is correctly) and restarts automatically a new measurement. This will be done 5 times and power off.
If there is any part in it (e.g. a C), tester starts to measure, shows result for some secons and will repeat measurment like a loop. It will never stop. Only if part is removed (then it will try only 5 times like no part at the beginning) or battery is empty.
For both testers config files are the same. Only change is the µC type in makefile. Other settings where copied from "clones".
Fuses on TC1 und T7 were different. But I can't remember how it was. I wrote the same fuses for both tester accidentally.
Now it is:
L: 0xFF
H: 0xD7
E: 0xFD (change like it is written in "clones")
LB: 0x3F
Any tips for me?
Regards
Chris
