Tutorials

The following tutorials are available for this architecture:

Configuration and Programming

ERIKA Enterprise is configured through RT-Druid and an OIL file.

The following sections describe the OIL fields customized for Microchip dsPIC33/PIC24 architecture.

MPLAB-X IDE Path

It is possible to choose the path in three different ways:

Specific environment variables: MPLAB_X_IDE_FILES
- E.g.: MPLAB_X_IDE_FILES=C:\Program Files (x86)\Microchip\MPLABX\v4.05
RT-Druid Eclipse IDE Property.
RT-Druid Configuration File Entry: preference_dspic33_pic24__path_for_mplab_x_ide
- E.g.: preference_dspic33_pic24__path_for_mplab_x_ide=C:\Program Files (x86)\Microchip\MPLABX\v4.05

Here is an example of RT-Druid configuration file.

MPLAB XC16 C Compiler Path

It is possible to choose the path in three different ways:

Specific environment variables: XC16_TOOLS
- E.g.: XC16_TOOLS=C:\Program Files (x86)\Microchip\xc16\v1.33
RT-Druid Eclipse IDE Property.
RT-Druid Configuration File Entry: preference_dspic33_pic24__path_for_xc16_compiler
- E.g.: preference_dspic33_pic24__path_for_xc16_compiler=C:\Program Files (x86)\Microchip\xc16\v1.33

Here is an example of RT-Druid configuration file.

CPU

CPU_DATA object must be set to DSPIC33_PIC24.

MODEL attribute of MCU_DATA supports for now the dsPIC33 value only.

Example of a CPU_DATA section:

   CPU_DATA = DSPIC33_PIC24 {
     MODEL = dsPIC33;
     ...
   };

MCU

MCU_DATA object supports for now the dsPIC33EV value only.

MODEL attribute of MCU_DATA supports for now the dsPIC33EV256GM106 value only.

Example of a MCU_DATA section:

 MCU_DATA = dsPIC33EV {
   MODEL = dsPIC33EV256GM106;
 };

BOARD

BOARD_DATA object supports for now the dsPIC33EV_SK value only.

Example of a BOARD_DATA section:

 BOARD_DATA = dsPIC33EV_SK;

Interrupt Handling

The Interrupt Handling support is microcontroller dependent. For each supported Microchip dsPIC33/PIC24 microcontroller family, the ISRs configuration of ERIKA3 is shown below.

OSEK/VDX Extensions

This Section contains information about the OSEK/VDX Extensions (or optional features) that have been implemented for the dsPIC33/PIC24 support.

System Timer

System Timer is microcontroller dependent so for each supported Microchip dsPIC33/PIC24 microcontroller family, the System Timer configuration of ERIKA Enterprise v3 is shown below.

dsPIC33EV Family

For the dsPIC33EV family of dsPIC33/PIC24 microcontrollers the System Timer is linked to Hardware Timers so the DEVICE attribute MUST be se to T1 orT2 or ... or T5 as shown below.

 COUNTER SystemTimer {
   MINCYCLE = 1;
   MAXALLOWEDVALUE = 65535;
   TICKSPERBASE = 1;
   TYPE = HARDWARE {
     DEVICE = "T1";
     SYSTEM_TIMER = TRUE;
   };
   SECONDSPERTICK = 0.001;
 };

-The '''dsPIC33EV''' family of '''dsPIC33/PIC24''' microcontrollers has an interrupt vector table which is stored in the flash memory. The lowest addresses of the interrupt vector table are allocated to the RESET and to the interrupt vectors. Interrupt handlers placed at lower addresses have higher hardware priorities than interrupt handlers placed at higher addresses so the '''PRIORITY''' attribute of the '''ISR''' object in the OIL is USELESS.
