Run and Test

After code compilation and flashing the

device, perform the following steps:

›

Check if LED D107 (1) is toggling its

state every 86 seconds:

–

Maximum value of 32-bit timer is

4294967295

–

Frequency of GPT12 module is 100

MHz

–

Prescaler of GPT2 block is set to 2

–

Timer T6 frequency is 100 MHz / 2

= 50 MHz, which means the value

of the 32-bit timer will be

incremented each 20 ns (1 / 50

MHz)

–

Overflow of 32-bit timer after ≈ 86 s

(4294967295 * 20 ns)

Check in the debugger if parameter

g_timerValue32Bit is incrementing
