PIT Driver Applications

There are three sample applications demonstrating how PIT module can be used in a user

application. The supported EVM boards for PIT sample application are MC56F8025DEMO and

MC56F8037EVM.

dac_pit_demo

{DSP56800E_Quick_Start Source}\..\sample_applications\EVM\dac_pit_demo

This application shows how PIT_0 and PIT_1 are driven by PIT_0 and PIT_1 timers in an

automatic mode, generating a sawtooth signals.

dac_cmp_demo

{DSP56800E_Quick_Start Source}\..\sample_applications\EVM\dac_cmp_demo

This application shows how PIT_0 and PIT_1 are driven by PIT_0 timer in an automatic mode,

generating a sawtooth signals. Analog Comparator module (CMP) is then used to compare the

PIT_0 and PIT_1 signals and sets one user LED accordingly.

adc_fmstr_demo

{DSP56800E_Quick_Start Source}\..\sample_applications\EVM\adc_fmstr_demo

Again, this application shows how PIT_0 and PIT_1 are driven by PIT_0 counter in an automatic

mode, generating a sawtooth signals. The ANA7 and ANB7 channels are sourced from PIT_0 and

PIT_1 and the ADC-measured values may be displayed in the FreeMASTER visualization tool.
