How long do you think it will take to execute all that code in the ISR - less that 25us ?
I think you need to look at pre-computing your values and putting them into a lookup table if you have any ... |

Rather than globally turning off syntax checking, I would create a header file with prototypes for the CCS functions you are using. That would at least remove the warnings from your code.

You should post this question here:http://www.microchip.com/forums/f238.aspx
Though frankly, I find the current version of MPLAB-X unusable with CCS compilers due to the bug you have found and the ... |

This is also a shocking example of how to use the RDA interrupt.
It needs to be short and quick you should not be getting a complete string nor should you be calling printf from within this interrupt ... |

Are you using the latest beta release (7.12) as I seem to recall having a similar issue a few versions ago.
I am having no problems with the latest release with CCS C.

Also, can you spot the trend ?
z = 48, p = 0
z = 49, p = 1
z = 50, p = 2
How about p = z - 48 ?

Apparently MPLAB X works the same way as the original MPLAB so it should pick up your installed compiler tools automatically - it did for me !
You should also note that it appears that you need a b ... |

Hi,
Your if statement reads (in English), if fok is greater than 10 OR fok is less than 35 then....
So, if fok = 20 then fok is less than 35 and if fok = 255 then fok is greater than 10 !

Hi,
You are getting the error because you are trying to access the variable ram as an array (ram[0]) but you have defined it as an 8-bit integer. Are you trying to check if bit 0 is a 1 ?

You should always add ERRORS to your #use RS232 line to ensure that any errors do not lock up the RS232 receive.

If you spend 10 minutes reading the CCS manual you should have no problem converting this to CCS code.

If you read the forum PCM Programmer gave you the link to then you will see that a PIC is not powerful enough nor contains the memory required to drive a graphics LCD with that resolution.

I would put a scope on the TX line from the PC to see if during boot Linux sends data. It may be that Linux looks for a modem on the port by sending an AT command which might mess up your PIC code ?
