psmmacker Posted February 22, 2017 Share Posted February 22, 2017 Why does green bleed and not any other colors Thxs paul Link to comment Share on other sites More sharing options...
Sibi Posted February 23, 2017 Share Posted February 23, 2017 Green led work on lover voltage then red and blue, so its bleed first. As i understand bleeding problem is in off state. In off its still have some voltage (not enough for red and blue) but enough for green. Look on the forum, Putting fets with resistors on ground solve problem.

psmmacker Posted February 23, 2017 Author Share Posted February 23, 2017 Did that changed all my colours from red to yellow maybe changing the capacitors value may work as i removed all my capictors and did a test and one row went yellow in one spot on my p4 but in duel it also changed the other p3 without the capacitors and i got new panels with no mosfet snd still the same issue i checked gnd i changed data cables i think diodes going on series or parallel dont know if this would work with pwm Series. Circuit hub75 output from shield Stm32 out diode on red to rgb x2 input hub 75 Stm32 out diode to green rgb 2 input hub 75 Stm32 out diode to blue rgb x2 input hub 75 Or Paralllel CIrcuit hub 75 output from shield From stm shield output Pin 1 diode then outpin 1 to panel input From stm shield output pin2 diode then outpin 2 to panel input From stm shield output Pin 3 diode then outpin 3 to panel input Miss pin 4 as its gnd From stm shield output Pin 5 diode then outpin 5 to panel input From stm shield output Pin 6 diode then outpin 6 to panel input From stm shield output pin 7 diode then output 7 to panel input A verible resister also on 1 gnd pin across each rgb changes the colour brightness aswell instead of software driven pwm aswell I did try this and it seem to work ok lucky 1 said about shift registers but it seem there.should be 6 pods for each rgb input to change colours Thanks Paul P2.5 with pod no green led seem to clear we need really need two pods across go and g1 out from stm discovery to panels And end pin to any of the tired Gnd Link to comment Share on other sites More sharing options...
