measure VOUT_HAL
ftana2
ftana1 "\n" return value: <ST>:000000
measure the analog output voltage of sen-
sor 1 with HAL-APB’s ADC
Example
=> ftana2
<= 0:00200
0x00200 = 512(dec) * 5 / 1024 = 2.5 V

<ST> board status
<P> 5 digit Period
<W> 5 digit Pulse width
Example
=> pr1 (OP-bit=0)
<= <ST>:013AE00A00
- Conversion of PWM-Period:
0x013AE = 5038
dec
/ 10000 = 0,5ms
- Conversion of Pulse width:
0x00A00 = 2560
dec
/ 10000 = 0,26ms
- Calculation of Duty-Cycle:
2560/ 5038 = 50,8%
get Bit time
?bt
return value: <ST>:
BT
BT as a 5-digit hex No.
get last acknowledge
time
?ack
return value: <ST>:0x
ACK
ACK as a 4-digit hex No.
returns the width of last acknowledge
pulse
