DIGITAL POT CONTROLLED WITH ENCODER
Hello to all . I would like to control a digital pot MAX-5484 , 1024 STEPS, 50K , with a BOURNS incremental encoder PEC-11R. I made a demo code to move the wiper of pot step by step in directions up/down with a pulse. According to PEC-11R data sheet with 1 pulse wiper moves 1 step of 1024. In my cas...

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 .

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 resistors ? what...

medelec35,
I use external oscillator ( a crystal 16 MHz ).
about verylongdelays code ( at main ) in decision branch there is " if TimeUpFlag? "..... is this correct , or " if TimeUpFlag=1 ?

Re: LONG TIME TIMER
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...

PIC16F1579 SUPPORT
I need to use PIC16F1579 for a project , but I noticed that that chip not supported by FC7...is there a possibility to add that chip in the PIC16F family to load my flowcode in the chip ?
thanks.
