Wrong I2C output on UDB4 board
Posted: Thu Feb 09, 2012 5:38 pm
Hello,
I'm trying to use the I2C on UDB4 board with Lubin's Block-set. I've done this on to other boards (with dsPIC30 and dsPIC33) and it had worked perfectly.
Unfortunately, when I'm trying it on UDB4 board (with dsPIC33fj256GP710a) the I2C signal that i get is very strange.
This is how I2C signal should look when everything works fine: When i look with oscilloscope on the I2C signal of the UDB4, it show non stoping bits in the SDA and SCL without any meaning.
This is the model that I've build:
Does someone have any idea why it happens?
Thanks,
Alpert.
