A "count" variable is shared + * between all three tasks. The two counter tasks should never be in a "ready" + * state at the same time. The controller task runs at the same priority as + * the continuous count task, and at a lower priority than the limited count + * task. + * + * One counter task loops indefinitely, incrementing the shared count variable + * on each iteration. To ensure it has exclusive access to the variable it + * raises it's priority above that of the controller task before each + * increment, lowering it again to it's original priority before starting the + * next iteration. + * + * The other counter task increments the shared count variable on each + * iteration of it's loop until the count has reached a limit of 0xff - at + * which point it suspends itself. It will not start a new loop until the + * controller task has made it "ready" again by calling vTaskResume (). + * This second counter task operates at a higher priority than controller + * task so does not need to worry about mutual exclusion of the counter + * variable. + * + * The controller task is in two sections. The first section controls and + * monitors the continuous count task. When this section is operational the + * limited count task is suspended. Likewise, the second section controls + * and monitors the limited count task. When this section is operational the + * continuous count task is suspended. + * + * In the first section the controller task first takes a copy of the shared + * count variable. To ensure mutual exclusion on the count variable it + * suspends the continuous count task, resuming it again when the copy has been + * taken. The controller task then sleeps for a fixed period - during which + * the continuous count task will execute and increment the shared variable. + * When the controller task wakes it checks that the continuous count task + * has executed by comparing the copy of the shared variable with its current + * value. This time, to ensure mutual exclusion, the scheduler itself is + * suspended with a call to vTaskSuspendAll (). This is for demonstration + * purposes only and is not a recommended technique due to its inefficiency. + * + * After a fixed number of iterations the controller task suspends the + * continuous count task, and moves on to its second section. + * + * At the start of the second section the shared variable is cleared to zero. + * The limited count task is then woken from it's suspension by a call to + * vTaskResume (). As this counter task operates at a higher priority than + * the controller task the controller task should not run again until the + * shared variable has been counted up to the limited value causing the counter + * task to suspend itself. The next line after vTaskResume () is therefore + * a check on the shared variable to ensure everything is as expected. + * + * + * The second test consists of a couple of very simple tasks that post onto a + * queue while the scheduler is suspended.

The R5F100LEA contains a little + * under 4K bytes of usable internal RAM. The RAM size restricts the number of + * demo tasks that can be created, and the demo creates 13 tasks, 4 queues and + * two timers. The RL78 range does however include parts with up to 32K bytes + * of RAM (at the time of writing). Using FreeRTOS on such a part will allow an + * application to make a more comprehensive use of FreeRTOS tasks, and other + * FreeRTOS features. + * + * In addition to the standard demo tasks, the following tasks, tests and timers + * are created within this file: + * + * "Reg test" tasks - These fill the registers with known values, then check + * that each register still contains its expected value. Each task uses a + * different set of values. The reg test tasks execute with a very low priority, + * so get preempted very frequently. A register containing an unexpected value + * is indicative of an error in the context switching mechanism. + * + * The "Demo" Timer and Callback Function: + * The demo timer callback function does nothing more than increment a variable. + * The period of the demo timer is set relative to the period of the check timer + * (described below). This allows the check timer to know how many times the + * demo timer callback function should execute between each execution of the + * check timer callback function. The variable incremented in the demo timer + * callback function is used to determine how many times the callback function + * has executed. + * + * The "Check" Timer and Callback Function: + * The check timer period is initially set to three seconds. The check timer + * callback function checks that all the standard demo tasks, the reg test tasks, + * and the demo timer are not only still executing, but are executing without + * reporting any errors. If the check timer discovers that a task or timer has + * stalled, or reported an error, then it changes its own period from the + * initial three seconds, to just 200ms. The check timer callback function also + * toggles the user LED each time it is called. This provides a visual + * indication of the system status: If the LED toggles every three seconds, + * then no issues have been discovered. If the LED toggles every 200ms, then an + * issue has been discovered with at least one task. + * + */ + +/* Scheduler include files. */ +#include "FreeRTOS.h" +#include "task.h" +#include "timers.h" + +/* Standard demo includes. */ +#include "dynamic.h" +#include "PollQ.h" +#include "blocktim.h" + +/* Hardware includes. */ +#include "port_iodefine.h" + +/* The period at which the check timer will expire, in ms, provided no errors +have been reported by any of the standard demo tasks. ms are converted to the +equivalent in ticks using the portTICK_RATE_MS constant. */ +#define mainCHECK_TIMER_PERIOD_MS ( 3000UL / portTICK_RATE_MS ) + +/* The period at which the check timer will expire, in ms, if an error has been +reported in one of the standard demo tasks, the check tasks, or the demo timer. +ms are converted to the equivalent in ticks using the portTICK_RATE_MS +constant. */ +#define mainERROR_CHECK_TIMER_PERIOD_MS ( 200UL / portTICK_RATE_MS ) + +/* These two definitions are used to set the period of the demo timer.
