How to charge the batteries via C?

[cosa]

Hi,

I'm searching for a piece of code that demonstrates how to charge the batteries. It's very inconvenient to upload the firmware every time you want to recharge the batteries.

Has anyone figured it out yet?

Thanks in advance,

Sorry but you don't need to upload the firmware after you recharge batteries at all. The firware does not erase because your battery goes low. How are you charging batteries ?

I write my own C(++) program - like example.c - and upload the .hex file to the robot. If I want to recharge the batteries I can't use the "press button up" mechanism because its implemented in the firmware (I guess so).
So every time I want to recharge the batteries I have to write the original firmware to the robot (and erase my program) and use the standard mechanism.
Now I'm searching for a piece of code to implement a recharge-function in my own c-program.
