The main things are to remove the "_t"s from the end of uint8, uint16 etc and switching the wires to use SDA on pin 20 and SCL on pin 21.</p> <p>This is of course assuming you're using the current Wire library that is included with Maple IDE v0.0.12. If you're using the new Wire library, the SDA pins are different. </p> http://forums.leaflabs.com/topic.php?id=1968#post-11409 Wed, 27 Jun 2012 06:00:14 +0000 Carl 11409@http://forums.leaflabs.com/ <p>Hi, I want to control a MCP4728 Evaluation board from microship.<br /> I got it running very easy on the arduino with this library:<br /> <a href="http://neuroelec.com/2011/02/mcp4728-library-for-arduino/" rel="nofollow">http://neuroelec.com/2011/02/mcp4728-library-for-arduino/</a></p> <p>With no previous experience with I2C the library helped me a lot. </p> <p>Now I just need to be able to do the same using the Maple IDE.</p> <p>I don't have the skillz to port over the library to MAPLE IDE and I don't really understand how I should control the DAC without it.</p> <p>Would be very happy if anyone helped me or just sent a link to a tutorial if there is one.</p> <p>Thank you.</p> <p>//Carl </p>
