We are pleased to announce that ShieldBuddy add-in v1.41 has been released. This adds PWM measurement utilities, the first of a number of GTM-based functions. The TC275 GTM TIM modules can be used to make PWM period and duty cycle measurements automatically and without interrupts. The PWM frequency must be in the range of 5.96Hz to 10MHz. The function used to make the measurement is “MeasurePwm()”. This has parameters as per:
MeasurePwm(uint8 _pin, uint32 *Period, uint32 *Duration, float *DutyRatio);
It expects to receive the address of the variable into which you want the new data to be inserted, e.g.
MeasurePwm(8, &PWM_Period0, &PWM_Duration0, &DutyRatio0);
The following ShieldBuddy pins can be used for this purpose:
0 1 2 3 4 5 6 7 8 9
10 11 12 13 14 15 17 18 19 20
21 24 25 27 28 29 31 33 35 37
38 39 44 45 46
You find full details of the functions in the user manual.
