|
|
|
|
UART: 115200N1, not more than 100ms between data bytes in command
|
|
To turn ON human terminal (without timeout) send "####"
|
|
|
|
Protocol: [ command line ]
|
|
'[' clears earlier input
|
|
'\n', '\r', ' ', '\t' are ignored
|
|
All messages are asynchroneous!
|
|
|
|
Commands:
|
|
Ax - turn on(x=1)/off(x=0) external alarm or check its value
|
|
Cx - set cooler PWM to x
|
|
d - (only when EBUG defined) go into debug commands
|
|
F - get flow sensor rate for 5s period
|
|
Hx - set heater PWM to x
|
|
L - check water level sensor value
|
|
Px - set pump PWM to x
|
|
R - reset MCU
|
|
Tx - get NTC temperature for channel x
|
|
t - get MCU temperature
|
|
V - get Vdd value *100V
|
|
|
|
Debugging commands:
|
|
A - show raw ADC value (next letter is index, 0..5)
|
|
F - get flow_cntr value & PB state
|
|
T - show raw T values
|
|
w - test watchdog
|
