hello everybody,
i have a problem with connection by i2c between pixy and arduino mega 2560, i had connect the pins sda a scl gnd and vcc to my 20 21 gnd and vcc aruino board, i load the i2c sketch but the serial out doesn’t print anything, someone else had the same problem and solved it?
Hi,
I am having the same problem as gianni too. I noticed the problem occurs when my Pixy uploaded with the new pixy_firmware-2.0.8.hex.
If my Pixy using the old firmware-1.0.2beta.hex its working fine, tho pan/tilt is not working.
In order for Pixy to communicate in I2C you have to change the ‘data out port’ of Pixy in PixyMon to ‘1’. Have you done that? Check the link for more details http://cmucam.org/projects/cmucam5/wiki/Hooking_up_Pixy_to_a_Microcontroller_like_an_Arduino.
Tell me if its working with yours.
