I think I may have a corrupted os on my controller. After the last upgrade it seems that there is a delay of about a second or two and pwm controls are not acting right. The reason that I believe that I may have a corrupted os is that I may have been too far away when I did the update. I tried to reload but it says that it is already the current version. Is there any way to force the update again? Thank you
DJ, Now looking like I have a wiring issue. confused
Wiring issues are frustrating but fixable. You need trace each wire out to see if it's connected as expected. Try to remember what you changes sense the last time it worked correctly. You may need to bet a multi meter with a continuity tester built in and make all wires are intact. This tester will also help with tracing wires and finding shorts. You may have two wires connected together that should not be or one connected to a ground. Also make sure all your connections are tight and true. Most problems come from bad connections or wires connected to the wrong place. Take it slow and start at the beginning (usefully where the power comes in). Good luck and keep us posted.
Thanks Dave, I went through all wiring. I solder all connections and make schematics as I go. My motors (dc motors) are on the digital outputs, and are driving the gates of transistors (igbt). What happens is at power up, before I get the ezb connected, some motors will just start on their own. This is very random and I think the problem might be that I do not have any pull down resistors on the gate of the transistors. I believe they are self turning on.
