I have the Me-Base Shield and I am trying to access the I2C through the A4/A5 pins on the Mediuno below. I am trying to connect an LCD (see link below)
For some reason I cannot get it to work. I thought that the Mediuno pins could be accessed through the Shield. I am guessing that these pins are not available, but wanted someone to verify. Please let me know.
hello jacob,If you use the Me-Base Sheild,you can found the i2c pins at every port (pins named SCL & SDA).
Hi Jacob and Indream,
I used the Makeblock ME-RJ11 adapter to connect my I2C display.
My display comes with an I2C connector which provides exactly the I2C pins from the ME-RJ11 adapter, but in a different pin order:
To connect the display, I used a crossover cable connection:
You can use any white RJ11 port 3…8 on the Me-Baseboard or Me-Baseshield, they are marked with SDA/SCL.
Warning: PORTS3…8 are valid for the ME-RJ11 only, please read the ME-RJ11 product usage description.
PORT1 and PORT2, both are designed to provide motor power V-M instead of +5V and have inverted power lines.
When done, just upload the example sketch - and you’re running.
Kind regards,
Thorsten
