Shield Base Axe401, onboard I2C

[BillyGreen1973]

Just a quick pointer,

Today I was playing with the Axe401, with a 24LC512 EEPROM in the on board socket (4k7 R's are in place), trying different #Slot programs.
I was having trouble using slot 4 (EEPROM), then I realised I needed to remove the H4 LED Enabled jumper to allow correct I2C comms.

Everything then worked fine once this is removed. It does say in the axe401.pdf about the LED...

"this can adversely affect using this pin for another purpose e.g. as a touch sensor input."

what it doesn't mention is that it DOES adversely affect I2C comms.

While this may be obvious to most, it can be quite frustrating for a beginer. So to use the I2C on the axe401 REMOVE H4 jumper!

Sorry about that and thanks for letting everyone know. I've made a note of it.

They're off and racing in Britain. As far as I know, the AXE401 is not available in Australia yet

Microzed seem to have stocked it for a few days now ...

You're right, hippy. I was looking under "New Products for March" panel, where the AXE401 did not crack a mention.

On the other hand, MicroZed's "New Products for March" lists the 14M chip and the 18-pin high power board as new for March. Frustrating but not your responsibility.
