Hi, the following is stated in the PollQ.c file in minimal: #define pollqPRODUCER_DELAY        ( ( portTickType ) 200 / portTICK_RATE_MS ) #define pollqCONSUMER_DELAY        ( pollqPRODUCER_DELAY – ( portTickType ) 20) This will not work if: portTICK_RATE_MS = 10 pollqCONSUMER_DELAY will then become 0, is that realy wanted. I suggest the following: #define pollqPRODUCER_DELAY        ( ( portTickType ) 200 / portTICK_RATE_MS ) #define pollqCONSUMER_DELAY        ( pollqPRODUCER_DELAY – ( portTickType ) 20 / portTICK_RATE_MS )

I think this is changed already in the latest version (?)
