Compiler/SM72442: Coding Problem

Tool/software: TI C/C++ Compiler

I am currently building the mppt circuit suggested with the sm72442. I started looking through the code and one of the programs is a .__c and therefore cannot compile. There is a file with the same name as an assembly file but you cannot compile an assembly code and C code at the same time to my knowledge. I was wondering if anyone had the actual c file for the batt_charg_i2c instead of the assembly one or if anyone has a fix for this.

Sorry our team who are supporting this device are all analog power engineers. I will see if we can find somebody to help you out.

Thank you. As I stated all I need is the bat_charge_i2c.c file.

Sorry we are still trying to find somebody to help with the digital part of the IC. I have also notified our management team to find ways to resolve the support gap issue. We are working on it but it takes time.

I just found some colleague has a document describing the use of the interface. Which I am checking if I can share with you directly. Will let you know next week.

That is for setting up the sm72442 on the dev board. I am looking for the battery charger file for the pic, using mplab.

Sorry I don't we can find the actual c file for the batt_charg_i2c. The SM72442 and SM72445 are very similar in the MPPT function. The biggest difference (may be the only difference) is that the latter added a "panel bypass mode", which stops buck and boost operation but just turn-on the bypass switch when VIN=~VOUT for highest efficiency.
