i am nwe to programing with pics and am trying to produce a sine wave with a freq. and amp. that are detrmend by the user in the code.
i am having truble in writing the code, if any one can asist i will be gratefull..
i have the easypic 7 with 18f45k22 pic

Dear all,
Would be cool there is a LIB for this common Accelerator MPU 6050.
Its quite common chip and used in many smartphone. Qould be cool there is code easy to go
thx

hi im new at programming. i have compilled two different sorce codes and want to use one chip to run both programms.
when i build them in mikroc pro the software builds but only the first program works. i have test the programs buy building the individualy and they work, but if put together i have a problem . can any one please assist me

I am in need of programming for a simple input pulse counter that will hold its count over power cycling, and reset to zero on demand. For use with PIC16F628A and 4 digit 7 segment common cathode display. Input pulse comes from a basic NPN sensor switch.

the project uses PIC 16F887 and I'm programming using MPLAB IDE low level assembly language. the microcontroller should be able to detect a change in frequency on an external pulse train and count the number of times the train changes frequency in a five minute period. the train has a resonant frequency of about 80kHz which the microcontroller can determine on just after start-up (after a delay of one minute). thereafter the train changes by about plus or minus 5kHz and after every change it returns to its resonant frequency.
