Hello, I recently bought a hakko FX-951 and it is a very good station but to my surprise it does not include in its menu any way to set temperatures in memory as it did in my old FX888D, I have asked the hakko technical service to confirm it and the answer was simply "we are sorry but this function is not included in FX-951". I have obtained the writable integrated circuit model where the programming code of the PCB is located. So I wanted to ask if anyone has a way to modify the code found in the integrated R5F2127 for "Hakk" the hakko and be able to add this function to this fantastic station, does anyone with programming knowledge want to collaborate with me? I would provide the FX888D and FX-951 rom or .bin for you to make a custom rom. I attachment a picture of the FX-951 PCB. Thank you.
