* Updates according to Kicad library convention

Signed-off-by: zisi <agzisim@gmail.com>

* Resolve issues #22, #23, #24, #25

Signed-off-by: zisi <agzisim@gmail.com>

* Fix silkscreen placement and zone cleanup

* Use one GND bottom plane and GND areas in front

Remove zero ohm resistors
To avoid connection with GNDD directly with motor GND use keep out area

Signed-off-by: zisi <agzisim@gmail.com>

* Add electrolytic capacitor, TVS-diode in PSU input

Capacitor reduces the voltage ripple of input voltage (long cable)
TVS-diode protect the PSU and all the board from surges and ESD events

Agis Zisimatos debfbcb2e0 Merge pull request #3 from berry120/master 
"counter" in cmd_proc() should be declared as static to persist its value across method invocations.
 2015-04-24 20:55:15 +03:00
berry120 1d74f24528 The counter variable in cmd_proc() must be static (to persist its value across method invocations.) This won't necessarily manifest itself as an issue all the while serial data is being streamed fast enough to keep it in the inner "while(Serial.available())" loop. However, when this is not the case (which happened with us) the counter resets itself to 0 on every repeat of the cmd_proc() method. This then overwrites the contents of the buffer from 0, resulting in no valid commands (potentially in rare cases, corrupted but syntactically valid commands could also manifest.) 2015-04-24 12:25:18 +01:00
