SISAM Command Language
This chapter describes SISAM Command Language, provides Command Language BNF and describes SISAM responses
Command Language Overview
SISAM supports the following commands
? |
Display name and firmware version |
H |
Display help message |
S<sync> |
Sample sole channel |
X<sync> |
Sample dual channels |
J<sync> |
Capture (sample to buffer) |
M<sync> |
Measure (time) pulses on RC5 |
O<data> |
Immediate output <data> byte to actuator’s pins |
o<data> |
Set <data> to be put on actuator’s pins right before sampling |
r<data> |
Set sampling rate |
U<test><speed> |
Test RS communication at the specified speed by sending sequence of characters |
<sync> |
= 0 – start immediatelly |
<sync> |
= 1 – sync – e.g. start with first non-zero octet |
<speed> |
= 0: 112K, 1: 225K, 2:450K, 3:900K |
<data> |
= 0..F,00..FF |
<test> |
= 0..F |
