vlgxejme Posted September 3, 2018 Share Posted September 3, 2018 Hi I have a pin2dmd with the firmware 2.58. I'm no longer able to adjust the brightness in the pin2dmd app. Any idea? I use pin2dmd.exe latest rev 2.53 thanks Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted September 4, 2018 Content Provider Share Posted September 4, 2018 I just tested with the latest firmware and pin2dmd.exe and had no problem. Is it running at full brightness ? If yes there could be a problem with the OE (enable) signal of the panels Link to comment Share on other sites More sharing options...
vlgxejme Posted September 4, 2018 Author Share Posted September 4, 2018 yes it always run at full brithness. What do you mean by OE signal. Can I do something? Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted September 5, 2018 Content Provider Share Posted September 5, 2018 Check the connection from the controller to the panel. OE is PIN15 on the HUB75 connector. Link to comment Share on other sites More sharing options...
vlgxejme Posted September 9, 2018 Author Share Posted September 9, 2018 I dissemblable the shield off the unclesash board, ans everythinks seem to be fine. I'm prety sure taht the brightness button was usable on the 2.55 firmware... It is possible to downgrade to it to make a test? and if so, where can I find the firmware since there is only the latest on github Link to comment Share on other sites More sharing options...
