I am trying to understand libraries. I am working with the ledcontrol.h library. I am able to drive a set of four seven segment displays using a max7219 with the following instructions from the library LedControl lc=LedControl(12,11,10,1); //wake the max7219 lc.shutdown(0,false); // Set the brightness to a medium values // lc.setIntensity(0,3); // and clear the display // lc.clearDisplay(0); lc.setRow(0,0,a[0]................lc.setRow(0,7,a[7]); this means I have to make each bit of my code relate to each of the seven segments. I understand I can put the max7219 into a decode mode that allows it to read hex and decode it into seven segment information to pass to the display. the datasheet calls this decode and says if I put 00001001 into the register it will perform this function. If I go to the libraries page in the reference and click on ledcontrol it sends me to a login page (I am already logged in) which then sends me to a blank page when I log in? update -- this happens on internet explorer now for all functions but not on firefox? Is it possible to turn the decode on with an instruction similar to the ones above so I can send hex data to drive the seven segment displays? |
