Do you have the parts needed to do programing? A usbasp programmer and a soic8 chip. Lots of information here Guide: how to flash ATtiny13a based drivers (NANJG, QLITE, etc.) with custom firmware

Or are you just asking about what code changes to make?

Hi Alberto. If you follow the guide, you’ll eventually have the .C file open in Atmel studio. You’ll see the code like it is shown here. Lines 149-153 look pretty relevant.

Also check out the BLF A6 FET+7135 Light Troubleshooting and Mod thread.

Hi, thanks for help. I already just check this sites before, also read the code many times but only understand how change the timmer of the turbo, no how to disable .

I am not a programmer, i only understand codes by observation.

Thanks.

Waiting for more answers.

Alberto.

I think if you change line #153 to a value of 255 this will disable the timeout altogether. Otherwise, putting // at the beginning of line 149 might do the job. Could be wrong on both accounts.

I believe that i start to understand how works the code, “change line #153 to a value of 255” only change the turbo timmer to a 255/2= 127,5 seg.

The other idea maybe work, but i try first to simply remove this:

” #define NON_WDT_TURBO ”

” #define TURBO_TIMEOUT 90 ”

Waiting to arrived the components to reprogram the chip.

If anyone knows for sure what to disable the turbo timmer, in other words, unlimited please share it.

Thanks.
