connecting an i2c device with an AXE020 project board.
February 22, 2010
I've been thinking about playing around with i2c devices and I want to find a way to connect them to my
Axe020 project board. This thing.
After some initial problems with finding the pins on the project board that correspond to scl and sda
on my Picaxe 28X1, I finally found out that they are connected to the digital in 3 and 4.
Then I saw that all digital input pins have 10k pull down resistors on the project board,
and I know that you need them connected to 4k7 pull up resistors to make them work with i2C devices.
This might be a really silly question, but will this be a problem, and if so, is there a way past it?
Lately I've been considering getting one of these to avoid future problems like this one.
Maybe I should get one before continuing with i2c?
