<h2>Protocol</h2>
|
||||
|
||||
<p>Any command have format “# CMD”, where # is device ID (the_conf.devID) or “-1” if there’s
|
||||
only one device at the bus. After it can be any number of spaces and command symbols.
|
||||
If the command recognized and it’s right, <code>ALL OK</code> would be returnded. If the command is bad, answer
|
||||
<code>BADCMD</code>. Error in command sintax: <code>ERR</code>. If the answer would take more than one line it would
|
||||
be ends by <code>DATAEND</code>.</p>
|
||||
|
||||
<h3>First symbol of commands</h3>
|
||||
|
||||
<ul>
|
||||
<li>(nothing except spaces) - <em>ping</em> command, device with given ID answers: <code>ALIVE</code></li>
|
||||
<li><strong>G</strong> - one of the <em>Getters</em> (depending on next text)</li>
|
||||
<li><strong>M</strong> - motors' manipulation</li>
|
||||
<li><strong>R</strong> - make <em>MCU software reboot</em> (next <code>status</code> getter will return <code>SOFTRESET=1</code>)</li>
|
||||
<li><strong>S</strong> - one of the <em>Setters</em></li>
|
||||
<li><strong>W</strong> - <em>write flash</em> command, use it to save new configuration data</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<p>All wrong commands will return <code>BADCMD</code>, commands with bad format or wrong number return <code>ERR</code>.
|
||||
Commands with lot of output ends with <code>DATAEND</code>. Some commands (like flash write) will return
|
||||
just <code>ALL OK</code> if succeed.</p>
|
||||
|
||||
<h3>Getters</h3>
|
||||
|
||||
<p>Getters returning more than one field ends with <code>DATAEND</code> meaning that’s all data.</p>
|
||||
|
||||
<ul>
|

<li><strong>A</strong> - get <em>ADC value</em>
|
||||
|
||||
<ul>

</code></p>
|
||||
|
||||
<p> All variables here are fields of <code>user_conf</code> struct.</p></li>
|
||||
<li><p><strong>R</strong> - get <em>raw ADC</em> values:</p>
|
||||
|
||||
<ul>
|
||||
<li>0 - Steppers current</li>
|
||||
<li>1 - Input voltage 12V</li>

DATAEND
|
||||
</code></p></li>
|
||||
<li><p><strong>S</strong> - get <em>motors' status</em>.</p>
|
||||
|
||||
<p> Values of <code>MOTORx</code> (state of given motor) can be one of following:</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>ACCEL</strong> - start moving with acceleration</li>
|
||||
<li><strong>DECEL</strong> - moving with deceleration</li>
|
||||
<li><strong>MOVE</strong> - moving with constant speed</li>
|
||||
<li><strong>MOVETO0</strong> - move towards 0 endswitch (negative direction)</li>
|
||||
<li><strong>MOVETO1</strong> - move towards 1 endswitch (positive direction)</li>
|
||||
<li><strong>MVSLOW</strong> - moving with slowest constant speed</li>
|
||||
<li><strong>SLEEP</strong> - don’t moving (normal state)</li>
|
||||
<li><strong>STOP</strong> - stop motor right now (by demand)</li>
|
||||
<li><strong>STOPZERO</strong> - stop motor and zero its position (on end-switch)</li>
|
||||
<li><strong>UNKNOWN</strong> - something wrong</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<p> Values of <code>ESWxy</code> (state of end-switch <code>y</code> of motor <code>x</code>) can be:</p>
|
||||
|
||||
<ul>

</ul>
|

<p> If reset occurs there’s two additional fields on first request after reset:</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>WDGRESET=1</strong> - watchdog’s reset occured</li>
|
||||
<li><strong>SOFTRESET=1</strong> - software (by user’s demand) reset occured</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<p> There also two fields:</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>POSx</strong> - position of given motor (negative values means that initialisation need)</li>
|
||||
<li><strong>STEPSLEFTx</strong> - (only when moving) amount of steps left</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<p> E.g.:
|
||||
<code>
|
||||
SOFTRESET=1
|
||||
MOTOR0=SLEEP
|
||||
POS0=-1
|
||||
ESW00=ERR
|
||||
ESW01=BTN
|
||||

||||
</code></p></li>
|
||||
<li><p><strong>T</strong> - get <em>MCU temperature</em>, e.g. <code>TEMP=365</code></p></li>
|
||||
</ul>
|
||||
|
||||
|
||||
<h3>Motors' manipulation</h3>
|
||||
|
||||
<p>Next char should be ‘0’ or ‘1’ — motor’s number. If wrong, <code>Num>1</code> answer would be returned.
|
||||
There’s only two commands in this section:</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>Mnum</strong> - move motor to <em>num</em> steps. Errors:
|
||||
|
||||
<ul>
|
||||
<li><strong>BadSteps</strong> - <em>num</em> isn’t a number</li>
|
||||
<li><strong>IsMoving</strong> - motor is still moving, stop it before</li>
|
||||
<li><strong>OnEndSwitch</strong> - the motor is on end-switch limiting moving in given direction</li>
|
||||
<li><strong>ZeroMove</strong> - user wants to move for 0 steps</li>
|
||||
<li><strong>TooBigNumber</strong> - amount of steps is greater than <code>MAXSTEPSx</code></li>
|
||||
</ul>
|
||||
</li>
|
||||
<li><strong>S</strong> - stop motor</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<h3>Setters</h3>
|
||||
|
||||
<p>Change of any setter takes place in MCU RAM immediately. To store them permanently run
|
||||
<em>write flash</em> command.</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>C#num</strong> - set current <em>speed</em> to <em>num</em> for motor #</li>
|
||||
<li><strong>D num</strong> - set <em>denominator</em> to number <em>num</em></li>
|
||||
<li><strong>E num</strong> - set <em>numerator</em></li>
|
||||
<li><strong>I num</strong> - set <em>device ID</em></li>
|
||||
<li><strong>M#num</strong> - set maxsteps (<em>num</em> is 1..65535) for motor <code>#</code></li>
|
||||
<li><strong>P num</strong> - properties of internal pullup (0 - disabled, other or without <code>num</code> - enabled)</li>
|
||||
<li><strong>R#num</strong> - set reverse for motor # (<em>num</em> == 0 turns reverse off, <em>num</em> == 1 turns it on)</li>
|
||||
<li><strong>S#num</strong> - set <em>speed</em> (<code>motspd</code>) to <em>num</em> for motor #</li>
|
||||
<li><strong>T num</strong> - set <em>end-switches threshold</em> (in ADU, near 0 for Hall switch, 2048 for user button
|
||||
and 4096 for released state)</li>
|
||||
<li><strong>U num</strong> - set <em>USART speed</em> to <em>num</em> bits per second</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<h3>Motor speed setters</h3>
|
||||
|
||||
<p>To set motor speed to <strong>N</strong> steps per second, give command <code>C</code> or <code>S</code> with argument equal to
|
||||
3000/N. E.g. to set current speed for DevID=0, motor0 to 50 steps per second give command <code>0SC050</code>.</p>
|
||||
|
||||
<h3>Denominator and numerator setters</h3>
|
||||
|
||||
<p>Have naxt letter similar to ADC getter (<strong>D</strong> - Vdd, <strong>I</strong> - motors' I, or <strong>M</strong> - motors' U).
|
||||
The value of numerator shouldn’t be very large as uint32_t used in multiplications.</p>
|
||||
|
||||
<h3>Device ID setter</h3>
|
||||
|
||||
<p>After this command device will immediately change it’s ID, if you “lost” device after this
|
||||
procedure you should reboot it or (if there’s only one device on the bus) call it by “universal ID”
|
||||
(-1).</p>
|
||||
|
||||
<h3>USART speed setter</h3>
|
||||
|
||||
<p>The USART speed will be changed after next reset (e.g. by <em>MCU software reboot</em> command), so it
|
||||
don’t work without storing in the flash. Check it twice before writing as wrong numbers can make device
|
||||
lost until next re-flashing.</p>
