hi all,

i am currently doing my graduation thesis on a 24v bms system.

my setup is:

FRDM33771BSPIEVB

FRDMkl25Z

8cell battery pack connnected to cell terminal 1-4 and 11-14.

 

Codewarrior, the evaluation gui and the demo/driver library have been installed.

 

i am completely new to programming but i find the demo code really clear and well written.

in the demo i changed the pcconfig values to the ones i am using, e.g. IntType from IntTPL to IntSPI and NoCells from 6 to 8. after this i build and flashed the MC3377x_demo.elf file to the kl25z and i expected to see some difference in the evaluation gui, but it was exactly the same as before the demo was uploaded.

 

i also tried changing led colors from red to blue and succesfully flashed it so i confirmed that the code was being uploaded because the rgb led turned blue.

 

i was just that the demo file would already have a working balancing function, am i doing something wrong?

is there anybody who is also working on an 8cell setup?

 

kind regards,

Bart
