Added mikroBUS socket symbol

[ppielorz]

Added mikroBUS socket symbol according to datasheet (http://download.mikroe.com/documents/standards/mikrobus/mikrobus-standard-specification-v200.pdf).

I didn't put GND pins to the bottom of the symbol because of original shape. I left all of the pins as Passive because this is just a connector, not a full device.

All contributions to the kicad library must follow the KiCad library convention

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

• [x] Provide a URL to a datasheet for the symbol(s) you are contributing
• [x] An example screenshot image is very helpful
• [x] Ensure that the associated footprints match the official footprint library
  • A new fitting footprint must be submitted if the library does not yet contain one.
• [ ] Check the output of the Travis automated check scripts - fix any errors as required
• [ ] Give a reason behind any intentional library convention rule violation.

Hello @ppielorz thanks for contributing,

I have not made a complete review, but the following points should be fixed for the moment:

• [x] Pin should be grouped by function, not according to their physical position
• [x] +3.3V at the top, GND stacked at the bottom
• [x] Pin type should be specified

Cheers, Joel

Hi Joel, Should I group these pins even though it's a connector?

Yes exactly, that's a KiCad policy.

@ppielorz thanks, doing a full review right now:

• [ ] ~~I think the symbol can be called simply mikroBUS isn't ?~~
• [x] Graphic style of SCL and SCK should be Line
• [x] You should group TX with RX to simplify the schematics, this break the rule of input on the left and output on the right but it's not a problem. All pins should be group by fucntion. For example serial port is a function, spi port is a function etc.
• [x] RST in bottom will be better to wire it
• [x] You should stack GND pins
• [x] You can have the symbol more symmetrical. Example below.

@myfreescalewebpage Referring to your remarks:

• [ ] I think the symbol can be called simply mikroBUS isn't ?

Well, in mikroBus datasheet there is a clear division between socket and addon board. Personally I would leave it but I can follow your advice if you wish.

• [ ] Graphic style of SCL and SCK should be Line

Done

• [ ] You should group TX with RX to simplify the schematics, this break the rule of input on the left and output on the right but it's not a problem. All pins should be group by fucntion. For example serial port is a function, spi port is a function etc.

Done. I changed a bit your proposition to get more linear pin number order but they are grouped.

• [ ] RST in bottom will be better to wire it

Done.

• [ ] You should stack GND pins

Done

• [ ] You can have the symbol more symmetrical. Example below.

Done

@ppielorz thanks for the fixes.

Ok, in this case keep like that. Can you simply change "socket" to "Socket" for consistency with the footprint name

Also, I just realized the footprint filter is not correct, you should correct to "mikroBUS*"

Cheers, Joel

[ppielorz]

Done.

@ppielorz thanks, just made a final review, notice a final bug here reported in travis: GND pins are not properly stacked. The rule is: first pin Power Input visible, other pin Passive invisible. To solve the issue on your symbol, can you set pin 16 Passive ? Thanks!

Thanks, just need to wait for the footprint now :)
