2 PHASE INTERLEAVED BUCK CONTROLLER

Hallo to all.
is there an example code, or a way to realize a 2 phase interleaved buck converter for FC8 , as in the design file ( page 8, figure 10 ) below ? It gives the MPLAB X project files, but I would like to realize that with FC8 .

C CODE TO FC8 CONVERSION

I would like to convert a code in C TO FC8. The firmware below is for a MCU , MSP430F5132 of Texas ...I would like to convert the main.c to FC8, to transfer to a PIC MCU for easier programming. Is it possible that , and how can I do it ? the firmware is a part of TIDA-010042 project of Texas Instr. ...

Re: LONG TIME TIMER

medelec35, ok, I found the way to display the numbers of security code...also I would like to reduce the number of buttons....a way is to use 3 buttons ...UP and DN to select the number 0-9 , and SET to input at circular buffer...is there a component for that , or a code example with numbers display...

Re: LONG TIME TIMER

medelec35, the timing is correct on hardware ...with a typical crystal the deviation is 2 seconds at 1 hour...its ok ... another issue...sometimes the security code not inserted correct ...it needs 2 or 3 times to get the message "security code ok "....its about accuracy or keyboard resist...

Medelec35,
thanks for your answer...is there a way to test the timer without waiting days ? how to calculate and set up the clock speed of the target ? ( I'll use a PIC16F1939 ).

Dear sirs, i would like to run a part of FC8 code for a long time ( some days to 1 month )...is it possible to do that and how ? when the code goes to that part ( a macro ) starts a timer that runs in the background...at the end of preset time, the code leave the macro and goes to a connection point...

unfortunately , I have no free pins in PIC , only E.2 (ADC7) and B.5 (ADC2) ....using a small code with ADC, then when Imax set a pin to 1 , and then use the IOC for that pin, that works some times, but because the main code has many time delays , I can't have permanent monitor of current...i think ...
