Hello, I'm using the DE2 board and currently trying to control a stepper motor but im having some trouble using the expansion header. The motor needs 5V input and i read in the manual that the header can support that however, i can only find a 3.3V supply.Any info or help would be greatly appreciated. Thanks.
Hi,DE2 Board provides two 40-pin expansion headers such as DC +5V (VCC5), DC +3.3V (VCC33). Refer “4.6 Using the Expansion Header” from the following DE2_User Manual_1.6, http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=183&no=30&partno=4 Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
