blingy Posted July 22, 2013 Report Share Posted July 22, 2013 Is anyone else using DIN Sync with an LPC17? Quote Link to comment Share on other sites More sharing options...
latigid on Posted July 22, 2013 Report Share Posted July 22, 2013 No, what's your set up? Have you level-shifted the 3.3 V signal? Quote Link to comment Share on other sites More sharing options...
blingy Posted July 22, 2013 Author Report Share Posted July 22, 2013 So far I've just put a din out on j28 and didn't measure a voltage at all when there should be 3.3v on run I believe. Then there would be something to level shift anyway. Quote Link to comment Share on other sites More sharing options...
latigid on Posted July 22, 2013 Report Share Posted July 22, 2013 Please explain your set up. Are you using the Wilba control surface? Do you have the SEQ running correctly? Have you edited the hardware config file? Quote Link to comment Share on other sites More sharing options...
TK. Posted July 22, 2013 Report Share Posted July 22, 2013 This is the schematic which shows the 74HCT541 based level shifter at J28: http://www.ucapps.de/mbhp/mbhp_core_lpc17_output_buffers.pdf The usage of this chip is not only recommended for voltage adaption, but also to protect the LPC17 IO pins against short circuits.
