I tried to make a C program via CCS can increment and decrement based on 2 BP, this is the web programming for my project to control the chopper by a logic signal at the output of a peak 16F877A I made an error in programming, if you wait a while "a" at the high state and a long "a" at the low state, the rapportcyclique will be always the half, only the frequency varies My program merely to vary the frequency, if you leave your finger on a BP is not what I expect, so you have a variable increment at the beginning of the program based actions on BP and Grace to manage if the various reports based cycliques.puis rappcyc and with the "if" part is the root made 10 one I already made but with delays différents.j 'and have a program to control the duty cycle with an accuracy of 10 percent. can help me find a good program following the idea that
I asked with a little correction, it requires very little.
I await the response
