APPLICATION NOTE
11.5. HAL 283x / HAL 2850 – Board commands
Note: For general board commands see Table 7.2 on page 21
Table 11–21:HAL 283x / HAL 2850 commands
Action
read PWM-Period and
Pulse width
(only HAL 2850)
Command Parameter
prN
N=0/1
return value:
<ST>:<P3><P2><P1><P0><W3><W2><W1><W0>
Remarks
N trigger on falling/rising PWM edge
<ST> board status (see Table 6–9
on page 20 for details)
<P> 4digit Period
<W>4digit Pulse width
mode switch
pcms
return value: return value:
<ST>:<R4><R3><R2><R1><R0>
Example
=> pr1 (OP-bit=0)
<= <ST>:13AE0A00
- Conversion of PWM-Period:
0x13AE = 5038_dec / 10000 = 0,5ms
- Conversion of Pulse width:
0x0A00 = 2560_dec / 10000 = 0,26ms
- Calculation of Duty-Cycle:
2560/ 5038 = 50,8%
