Forum members can't provide you good advice if you don't supply correct or complete information. Proof read your post before submitting next time. Last thing to check is, make sure the MSSP module (I2C/SPI) is disabled if you are not planning to use it. SSPCON1.SSPEN = 0; // <bit 5> disable MSSP mod...

Problem: PortC pin 3 ,4 and 5 can not output anything

This is because you configured all pins of PortC as inputs.

The #include *.h header file declaration(s) must be placed at the very top of the *.c source file(s). This is very important because code elements below these are use to inform the linker where to get things like functions, variable types + sizes, arguments or pointers passed, constants ect... so it...

Quick answer... you can't using standard variable types. The compiler only supports a 32-bit sized variable type. But this does not mean you can't perform useful tests on the data like comparing the SN to a number you are looking for. It just requires a bit more processing effort to do so. In this s...

PORTC.f0 ==0; PORTC.f0 ==1; should be... PORTC.f0 = 0; PORTC.f0 = 1; A single "=" is the assignment operator i.e. X = 9; or X is assigned the value 9. A double "==" is the "equal to" operator only used when performing relational comparison tests i.e. if (x == 9) { do something} --- if (previous2 && ...

Can anyone give me a suggestion on how to handle the time changes every Spring and Fall? Daylight Saving Time (DST) begins at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. Read and compare the RTCC time, date, and day of the week registers for...

I suspect the mikroC I2C initialization is not taking into account the high clock speed. You might try adjusting the system clock postscaler setting in the compiler "edit project" window. Doing so will lower the clock frequency that drives the peripherals internally. If you study the datasheet oscil...

Don't forget to set the TRIS registers and disable the analog functions for the I2C port pins too.

Do you have pull-up resistors on the bus lines?

100 messages of 128 bytes each = 12800 bytes. Regardless of the coding methodology the sheer quantity of data you expect to store will exceed the RAM space offerings for all 8-bit PIC family of devices (8k max). Moving to a 16-bit or 32-bit PIC device will increase RAM space size offerings to fit yo...

To toggle a bit mikroC has the "sbit" command. See help file.

Another way to toggle the bit state is to use bitwise masking.
ex...
x = x & 0xFE; // this clears bit 0 to 0 using bitwise AND function
x = x | 0x01; // this sets bit 0 to 1 using bitwise OR function

If you haven't already fixed this... if ((INTCON.RBIF == 1) && (INTCON.RBIE=1)) should be... if ((INTCON.RBIF == 1) && (INTCON.RBIE == 1)) Better still... if ((INTCON.RBIF) && (INTCON.RBIE)) Also the IOC is not a very good idea when using mechanical switches because the IOC hardware does not provide...

You forgot to clear the timer 1 interrupt flag bit after servicing the interrupt.

hi, does anyone have an example code for the AD8402 for me?

Why not try reading the datasheet first and make an attempt to learn how to write the code yourself before asking others to do it for you? This is a very simple device to write code for.
SPI, shift out 2 bytes, address byte then data byte.
