Current sensing in STEVAL-ESC001V1

[srinath mallikarjunan]

Hi

I got the above board and am trying to understand the current sensing in 3 shunt resistor topology.

There seem to be a bunch of C files just for F3xx alone, but only single files for F4xx. Could someone explain which files are relevant for the eval board ?

I am looking at the files...

R3_1_F30X_PWMnCurrFdbkClass.c 

R3_2_F30X_PWMnCurrFdbkClass.c

R3_4_F30X_PWMnCurrFdbkClass.c 

AND

R3_F4XX_PWMnCurrFdbkClass.c 

Is the PWM timing and ADC input capture split into 3 files for F30x ?

If so why ?

Dear user,

the relevant file to understand the current sensing of the STEVAL-ESC001v1 is the R3_1_F30X_PWMnCurrFdbkClass.c. ESC001v1 actually uses only 1 ADC to do current sensing, even if 4 ADCs are present in the chip. It is why it is called R3_1_F30.....

Best regards
