* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the first. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo1 project is configured for a PIC18F4620 device. Main.c starts 9
* tasks (including the idle task).
* This first demo is included to do a quick check on the FreeRTOS
* installation. It is also included to demonstrate a minimal project-setup
* to use FreeRTOS in a wizC environment.
*
* Eight independant tasks are created. All tasks share the same taskcode.
* Each task blinks a different led on portB. The blinkrate for each task
* is different, but chosen in such a way that portB will show a binary
* counter pattern. All blinkrates are derived from a single master-rate.
* By default, this masterrate is set to 100 milliseconds. Although such
* a low value will make it almost impossible to see some of the leds
* actually blink, it is a good value when using the wizC-simulator.
* When testing on a real chip, changing the value to eg. 500 milliseconds
* would be appropiate.

* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the second. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo2 project is configured for a PIC18F4620 device. Main.c starts 12
* tasks (including the idle task). See the indicated files in the demo/common
* directory for more information.
*
* demo/common/minimal/integer.c: Creates 1 task
* demo/common/minimal/PollQ.c: Creates 2 tasks
* demo/common/minimal/semtest.c: Creates 4 tasks
* demo/common/minimal/flash.c: Creates 3 tasks
*
* Main.c also creates a check task. This periodically checks that all the
* other tasks are still running and have not experienced any unexpected
* results. If all the other tasks are executing correctly an LED is flashed
* once every mainCHECK_PERIOD milliseconds. If any of the tasks have not
* executed, or report an error, the frequency of the LED flash will increase
* to mainERROR_FLASH_RATE.
*
* On entry to main an 'X' is transmitted. Monitoring the serial port using a
* dumb terminal allows for verification that the device is not continuously
* being reset (no more than one 'X' should be transmitted).
*
* http://www.FreeRTOS.org contains important information on the use of the

* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the third. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo3 project is configured for a PIC18F4620 device. Main.c starts 12
* tasks (including the idle task). See the indicated files in the demo/common
* directory for more information.
*
* demo/common/minimal/integer.c: Creates 1 task
* demo/common/minimal/BlockQ.c: Creates 6 tasks
* demo/common/minimal/flash.c: Creates 3 tasks
*
* Main.c also creates a check task. This periodically checks that all the
* other tasks are still running and have not experienced any unexpected
* results. If all the other tasks are executing correctly an LED is flashed
* once every mainCHECK_PERIOD milliseconds. If any of the tasks have not
* executed, or report an error, the frequency of the LED flash will increase
* to mainERROR_FLASH_RATE.
*
* On entry to main an 'X' is transmitted. Monitoring the serial port using a
* dumb terminal allows for verification that the device is not continuously
* being reset (no more than one 'X' should be transmitted).
*
* http://www.FreeRTOS.org contains important information on the use of the

* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the fourth. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo4 project is configured for a PIC18F4620 device. Main.c starts 11
* tasks (including the idle task). See the indicated files in the demo/common
* directory for more information.
*
* demo/common/minimal/integer.c: Creates 1 task
* demo/common/minimal/dynamic.c: Creates 5 tasks
* demo/common/minimal/flash.c: Creates 3 tasks
*
* Main.c also creates a check task. This periodically checks that all the
* other tasks are still running and have not experienced any unexpected
* results. If all the other tasks are executing correctly an LED is flashed
* once every mainCHECK_PERIOD milliseconds. If any of the tasks have not
* executed, or report an error, the frequency of the LED flash will increase
* to mainERROR_FLASH_RATE.
*
* On entry to main an 'X' is transmitted. Monitoring the serial port using a
* dumb terminal allows for verification that the device is not continuously
* being reset (no more than one 'X' should be transmitted).
*
* http://www.FreeRTOS.org contains important information on the use of the

/*
* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the fifth. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo5 project is configured for a PIC18F4620 device. Main.c starts 13
* tasks (including the idle task). See the indicated files in the demo/common
* directory for more information.
*
* demo/common/minimal/flop.c: Creates 8 tasks
* demo/common/minimal/flash.c: Creates 3 tasks
*
* Main.c also creates a check task. This periodically checks that all the
* other tasks are still running and have not experienced any unexpected
* results. If all the other tasks are executing correctly an LED is flashed
* once every mainCHECK_PERIOD milliseconds. If any of the tasks have not
* executed, or report an error, the frequency of the LED flash will increase
* to mainERROR_FLASH_RATE.
*
* On entry to main an 'X' is transmitted. Monitoring the serial port using a
* dumb terminal allows for verification that the device is not continuously
* being reset (no more than one 'X' should be transmitted).
*
* http://www.FreeRTOS.org contains important information on the use of the
* wizC PIC18F port.

* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the seventh. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo7 project is configured for a PIC18F4620 device. Main.c starts 10
* tasks (including the idle task). See the indicated files in the demo/common
* directory for more information.
*
* demo/common/minimal/flash.c: Creates 3 tasks
* demo/common/minimal/death.c: Creates 1 controltask and
* creates/deletes 4 suicidaltasks
*
* Main.c also creates a check task. This periodically checks that all the
* other tasks are still running and have not experienced any unexpected
* results. If all the other tasks are executing correctly an LED is flashed
* once every mainCHECK_PERIOD milliseconds. If any of the tasks have not
* executed, or report an error, the frequency of the LED flash will increase
* to mainERROR_FLASH_RATE.
*
* On entry to main an 'X' is transmitted. Monitoring the serial port using a
* dumb terminal allows for verification that the device is not continuously
* being reset (no more than one 'X' should be transmitted).
*
* http://www.FreeRTOS.org contains important information on the use of the
