Re: Can we come up with a Standard Plug/Socket for I2C

Surely that defeats the object of a 2-wire interface. Are there many modules which would use both I2C and SPI at the same time? BTW: We have a 2x13 connector which includes a good selection...

Re: Can we come up with a Standard Plug/Socket for I2C

The direct pin numbering and ribbon numbering sounds good to me, and nice and logical too. It could even be optional to use 2x3 connectors for boards which plan to directly connect anyway, with a clear 1x6 version for modules which may be used with breadboards etc. Sounds excellent. Colours...I'd pi...

Re: Can we come up with a Standard Plug/Socket for I2C

The single inline connector still my preference (it is a lot easier to use on prototype boards and we can avoid another set of pins to remember) -- you'd be able to make up a series of bus connectors in 2 mins on stripboard, otherwise you'd need custom pcbs. I like the idea of building in the key (f...

Re: Can we come up with a Standard Plug/Socket for I2C

The 2x3 (or other double ones) are not friendly for breadboards or prototyping, so I would suggest any standard would have to have a 1x version. The best solution I can think of so far (although I really don't know lol) : Module Pins 5V 3V3 SDA SCL INT/NC GND RPi Cable (5x1 + a single female jumper ...

Re: Can we come up with a Standard Plug/Socket for I2C

I agree with the need to include the 5V. Unfortunately, there are two layouts even on the RPi itself (P5 included). The layout I've gone for is: 5x1 Connector (better for prototyping boards) - also allows the 5V pin to be dropped when not wanted: 5V 3V3 SCL SDA GND It was also influenced by the pino...

Now I just have to get back to where I was before I messed up! This is kind of why I asked in an earlier posting about backing up an SD card when a stable setup was reached.
Hopefully someone will pick up the flag and add backup options into NOOBS.

If I understand correctly, all you need to do is press shift when you power up and you'll get back to the NOOBS install.

The key steps are to connect up the RPi without any changes with a direct LAN cable: 1. Find out the IP address of the Ubuntu laptop that gets allocated.

Re: Looking to port my game to run on Pi or other ARM board

I had a go with monogame on the Raspberry Pi about 12-9 months ago, so I would be interested to see what has happened since.

At the time I didn't get very far in the time I had available, I got a few demos running but was unable to get anything compiled myself and running.

Could you post some pics your slim RPi, it is always great to see "frankinpis"?

How much higher is the USB port over the ...
