Is it possible to convert STM8 hex to C code?
« on: December 07, 2019, 01:20:51 am »
Hi!
I have a battery charger with an STM8S003F3 in there.
I would like to change a startup function and add a reset/restart button function.
I know, I could add the reset manually on the pcb too, but just for fun I would poke around the firmware.

Is it possible to convert the firmware from this uC to C/C++ code if I read out the content?

Thanks.

No, not in any way you would want. Try reading out the code first then go from there.

It is impossible automatically. However, it is an 8K device, and the real HEX size is probably less. If you know what you are doing, you can reverse that in a couple days.
