Another problem is that the frequency of data aquisition that i'm implementing is getting lower as long as the program runs so after some minutes they are getting in a lower frequency. Does anybody know why this happens? Sounds like a code problem. It certainly isn't due to the PIC. Post your code ...

PIC 16F/18F series system clock is Fosc/4, meaning the instruction clock will run at 8MHz internally with 32MHz input. The internal PLL is rated to 64MHz max so applying the 32MHz input with the PLL enabled will yield unpredictable behavior. This is because the PLL module applies a x4 multiplier pus...

The "printout" command does not handle unsigned long (32-bit) variable types. Also your printout command is applying the "%d" conversion format which is for signed int (16-bit) variable types. See the help file for more details. And while you're there take a look at the "LongToStr" and "UARTx_Write_...

Just one observation on the schematic... +5V to power the SD card???

The electrical specification for maximum Vdd voltage for any type or brand SD card is +3.6V, above this you risk damaging it.

Not knowing the ADC part, and assuming they are all the same, you might get away with chip selecting all 5 and issuing the conversion command at once. This assumes the data clocked back from each during this process is zero minimizing bus contention saving you some cycle time. Of course the read bac...

I looked at the ADuM3150 for use in an intrinsically safe product awhile back. For my needs the prop delays were acceptable. The question is what are you communicating with where 14/35 nS of prop delay is a problem? The DCLK mode does compensate for the internal delays. If the mikroC SPI library is ...

1. ADC result averaging.
2. Simple RC filtering on ADC inputs.
3. Combination of the two.

I have a large project that compiles and functions correctly with SD media using mikroC V6.62 and FAT32 library package version 1483703156. I just upgraded the compiler to V7.10 with the built-in FAT32 library and now my SD media fails to initialize (error code -3). I even tried uninstalling the FAT...

A useful feature to add to all the compiler statistics tools would be to have a listing that shows RAM usage by function.
This would include local automatic and static variables, string literals, unions, structs, and possibly the duration of each.

This is always a tricky thing to implement. Typically passing data by value is faster for small amounts of data because there is low overhead for addressing. But in some instances passing data by reference is faster when many arguments are being accessed. In your case it may take a few tries to code...

Using internal FVR reference but applying an external ground reference?
Should it not be...

Much like the mikroC IDE, the MPLAB X IDE internal simulator is not very comprehensive and does not support peripheral operations outside of reading and writing PIC registers. Things like timed interrupts are not supported. However as you already know Proteus does support his simulation functionalit...

I am using PIC18F13K22 and MikroC PRO for PIC v6.6.3, I could only find Library for PWM1, I want to use PWM2 also. Please suggest how to add library? Surjit, you are not paying attention. The PIC18F13K22 only has one PWM peripheral module that controls 4 output pins with alternate phases used to dr...

You also might look in the help file for the subject "Escape Sequences" for other useful string termination shortcuts besides "\r\n" as Hexreader pointed out.

This may help.
