Hands-On RTOS with Microcontrollers

Setting up the code

Here's the updated GreenTaskA() – only a single line has changed. This excerpt has been taken from mainPolledExample.c:

void GreenTaskA( void* argument ){  uint_fast8_t count = 0;  while(1)  {    //every 5 times through the loop, set the flag    if(++count >= 5)    {      count = 0;      SEGGER_SYSVIEW_PrintfHost("Task A (green LED) sets flag");      flag = 1; //set 'flag' to 1 to "signal" BlueTaskB to run

Instead of calling xSmeaphoreGive(), we're simply setting the flag variable to 1.

A similar small change has been made to BlueTaskB(), trading out a while loop that polls on flag, instead of using xSemaphoreTake(). This can be seen in the following excerpt from mainPolledExample.c:

void BlueTaskB( void* argument ){  while(1)  { SEGGER_SYSVIEW_PrintfHost("Task ...
