+Shutter control 
+===============
+
+Works with bi-stable shutter. 
+You can find the device in `/dev/shutterX` (symlink to `/dev/ttyUSBX`).
+
+## Pinout
+
+**PB0** (pullup in) - hall (or reed switch) sensor input (active low) - opened shutter detector
+
+**PB11** (pullup in) - CCD or button input: open at low signal, close at high
+
+**PA3** (ADC in) - shutter voltage (approx 1/12 U)
+
+**PA5** (PP out) - TLE5205 IN2
+
+**PA6** (PP out) - TLE5205 IN1
+
+**PA7** (pullup in) - TLE5205 FB
+
+**PA10** (PP out) - USB pullup (active low)
+
+**PA11**, **PA12** - USB
+
+**PA13**, **PA14** - SWD
+
+## Commands
+
+* '0' - shutter CLO
+* '1' - shutter OPE
+* '2' - shutter HIZ
+* 'A' - get raw ADC values
+* 'C' - close shutter  / abort exposition
+* 'E n' - expose for n milliseconds
+* 'O' - open shutter
+* 'R' - software reset
+* 'S' - get shutter state; also hall and ccd inputs state (1 - active)
+* 't' - get MCU temperature (/10degC)
+* 'T' - get Tms
+* 'v' - get Vdd (/100V)
+* 'V' - get shutter voltage (/100V)
+* 'W' - test watchdog
+
+If you will enter wrong long message, will receive its echo back. Any wrong short command will show help list.
+
+### Shutter control
+Commands '0', '1' and '2' should be used only for debugging purposes.
+To open/close shutter use only 'O', 'C' and 'E' commands.
+
+When opening or closing shutter you will first receive an answer: `OK` if command could be done or `ERR` if there's insufficient voltage on capacitor or shutter is absent.
+After opened the message `shutter=opened` will appear. After closing you will receive messages `exptime=xxx` (when `xxx` is approx. exp. time in milliseconds) and `shutter=closed`.
+
+Command 'E' could return `OK`, `ERR` or `ERRNUM`/`I32OVERFLOW` in wrong number format (number could be decimal, 0x.. - hexadecimal, b.. - binary or 0.. - octal).
+
+When exposition starts you will receive message `OK` and `shutter=opened`. After its end you'll got `exptime=...`, `shutter=closed`.
+If shutter can't be closed, you will give a lots of "exp=cantclose" and different error messages until problem be solved. To stop this error messages give command 'O'.
+
+### Different commands
+* 'A' will show raw values for all ADC channels: 0. - capacitor voltage, 1 - MCU temperature, 2 - MCU Vdd. You will give messages like `adcX=val`.
+
+* 't' - `mcut=val`, where val = T*10 degrC.
+
+* 'T' - `tms=val`, val in ms.
+
+* 'v' - `vdd=val`, val in V*100
+
+* 'V' - "voltage=val", val in V*100
+
+* 'S' - several answers:
+  * `shutter=`: `closed`, `opened`, `error`, `process`, `wait` or `exposing` - shutter state 
+  * `exptime=...` (only when shutter is opened) - show time since opening
+  * `regstate=`: `open`, `close`, `off` or `hiZ` - TLE5205 outputs state
+  * `fbstate=`: `0` or `1` - TLE5205 FB out state (1 - error)
+  * `hall=`: `0` or `1` - 1 for opened shutter, 0 for closed
+  * `ccd=`: `0` or `1` - 1 for active (closed contacts) state of "CCD" input
