uC/OS-II, The Real-Time Kernel PIC18xxx (Large Model) READ ME FILE V1.01 - December 20, 2002 ------------------------------ MPLAB-C18 C COMPILER --------------------------- 1) The current version of the Microchip PIC18 port is based on the Microchip MPLAB C18 compiler version 2.09.24 or higher. v2.00 has bugs. Microchip Technology Inc. 2355 West Chandler Blvd. Chandler, AZ 85224-6199 USA 480-792-7200 480-792-7277 (FAX) www.microchip.com 2) This port was tested using MPLAB IDE v6.00.20 Simulator and was tested on the PICDEM 2 Plus Demo Board. The tested processor was a PIC18F452. 3) The following settings were set for the C18 C compiler: -mL -Ls -O- ------------------------------ PIC18 PORT NOTES ------------------------------- 1) The port installation batch file (INSTALL.BAT) places the PIC18 port in the following directory of the selected drive: \SOFTWARE\uCOS-II\PIC18\MPLAB-C18 This directory contains the following sub-directories: \SOFTWARE\uCOS-II\PIC18\MPLAB-C18\SOURCE This directory contains the port source files. \SOFTWARE\uCOS-II\PIC18\MPLAB-C18\WORK This directory contains the port source files as well as the sample test code (i.e. TEST.C). \SOFTWARE\uCOS-II\PIC18\MPLAB-C18\LIBRARY This directory contains MPLAB C18 Library files that were modified to to use the large memory space and a large stack. The XLCD library was also modified to work on the PICDEM 2 PLUS Demo Board. 2) The port makes use of the PICs timer #0 for the tick ISR (OSTickISR()). 3) You must use a large code model, large data model, and a large stack. This includes the libraries that you are using. Modified .bat files to build the libraries are included. 4) Integer promotion must be disabled. The default storage class must be Auto. Optimizations must be disabled for now. 5) *.lkr scripts are included both with the debugger and without. These scripts set the memory space to be one contigious space to make use of the large memory and large stack option ( -ls ml). Large memory is needed because uC/OS-II uses more than 0xFF bytes of ram. 6) Some modifications can be made to uCOS_II.H and OS_CORE.C to save RAM. These modifications make the code read out of the program memory/ROM. The following line is modified in uCOS_II.H: /* Microchip PIC18xxx specific - lookup in program memory because of limited RAM space */ extern rom INT8U const OSMapTbl[]; /* Priority->Bit Mask lookup table */ extern rom INT8U const OSUnMapTbl[]; /* Priority->Index lookup table */ /* End Microchip PIC18xxx specific */ The following lines are modified in OS_CORE.C: /* Microchip PIC18xxx specific - lookup in program memory because of limited RAM space */ rom INT8U const OSMapTbl[] = {0x01, 0x02, 0x04, 0x08, 0x10, 0x20, 0x40, 0x80}; /* End Microchip PIC18xxx specific */ /* Microchip PIC18xxx specific - lookup in program memory because of limited RAM space */ rom INT8U const OSUnMapTbl[] = { /* End Microchip PIC18xxx specific */ ------------------------------ REPORTING PROBLEMS ----------------------------- If you find a problem (i.e. bug) in this port, do not hesitate to report the problem to me: 1) Through the INTERNET: My INTERNET address is: nathan@sputnickonline.com 2) By writing to me: Nathan Brown CPO 397 PO Box 7001 Longview, TX 75607 U.S.A. 3) By calling me (after 7PM Central time, US): (903) 446-6123 (630) 563-1171 (FAX) Make sure that the problem you are reporting is in or this port and not uC/OS-II or your application. ------------------------------ PIC18 RELEASE NOTES --------------------------- December 20, 2002: v1.01 ------------------------ 1) Added the ablity work with interrupt priority levels. A new OS_ENTER_CRITICAL_HIGH() function was added to allow for disabling high priority interrupts. OS_ENTER_CRITICAL() only disables low priority interrupts when priority levels are enabled, otherwise it disables all. 2) Interrupt handling does not save the program return stack unless the OS is switching tasks. Provides a speedup. 3) Saved in context return 24 and 32 bit values. 8 bit numbers use WREG, which is saved. 16 return values use PRODH:PRODL which is also saved. Others up to 32 bits use AARGB0:AARGB1:AARGB2:AARGB3. October 30, 2002: V1.00 ------------------------ 1) First release of the PIC18 port.
