  1. Finally i manage to complete the procedere with succes i do not know what is the problem but now i have a recognized ledwiz clone. I have fixed dll access violation error with new dll and I have an original working ledwiz so i know how it should work but now i have 5v when led is off and it only shot down led when i put britness to 0. Essentially on off button in test led NewLedTester.exe do not work for me. I took 5V from arduino mega pin 22 and connect small RGB LED to pin 24,26,28
  2. Hi to all i have tried everything with no result at all. My arduino mega china clone have (really stange) DFU so first time i am able to flash it with FLIP and all seems ok and it is recongnized from SimpleLEDTest.exe (id 4????) but signal from port are wrong and it is impossible to use. I have tried to reflash with flip with the result that it is no more recognized by SimpleLEDTest (No led controller detected) I have USBASP and 10 to 6 pin adapter so i started back from zero and i have no error at all and i ended all part with perfect result i have reattached mega with usb and i have 3 device (ultimate ....) with libusb driver but SimpleLEDTest or Change ArduLW ID give me no device (No led controller detected) I have used zadig to change usb driver to winusb and i have 3 device called UltimaPincontroll but SimpleLEDTest or Change ArduLW ID give me no device (No led controller detected) I am using win 10 and for me it is difficoulkt to find a win7 pc to try over it is possibile to use a virtual machine? I have tried more then 10 times. Please help me to figure out the problem

Pin 1 of hub75 is the one with red ribbon and an arrow over it is this correct? 4 status led Led on STM are off only th red one is on all other led are red, and i see an usb device on windows? Pheraps it is in the wrong devide mode? I have no sd no schield and latest 2.60 firmware with direct connection and only want to test pc connection and panel connection I have updade ST-Link firmware and declared in instruction than reflashed 2.60 firmware I have find this on instruction 1) Troubleshoot with the on Board LED´s  BLUE led = input DATA received (toggling)  RED led = SD Card error / Device Mode 0 on startup (use BLUE USER Button to get in to it)  ORANGE led= smart color change detected (toggling)  GREEN led = hash color change detected (toggling) 2)Device Modes: 1 - PinMame USB Mode with output to RGB DMD (16Pin HUB75 or HUB08) 2 - PinMame USB Mode with output to Pinball DMD (14Pin PinDMD Header) 3 - WPC Input – input from PinDMD -> output to RGB DMD (HUB75 / HUB08) 4 - STERN Input – input from PinDMD -> output to RGB DMD (HUB75 / HUB08) 3) Switch to Device Mode 0 to have USB access  Press the “BLUE USER” Button at the boot OR boot with NO SD CARD or with NO Config file on the SD Card
  5. Thanks a lot lucky1 i'll triple check connection even i am quite sure that they are correct and i'll buy an original STM32F4 board asap. Let me ask tree question just to help me to point out if i have made some mistake: 1)i have powered stm32F4 board from mini usb connector it is enouth or i have to power it with my 5V 20 AMP power that is connected only to led panel? 2)for virtual pinball i have to use micro or mini usb or both for data connection? 3)if something is wrong or cheap chinese board are not working is there a way to test led panel because the are completely black i do non t see anaything, they seems completely powered off Thanks for your help and beautiful work.
  6. Unfortunatly i have buy one i have tried it but with no result led panel are totally off. How i can test if Led panel are ok or hoe i can test STM32F4 without panel? Firmware is flashed correctly i belive and windown recognize the board using zadig. Please help me thanks i 'll buy an original one but i want to test led panel if it is possible. Just to test i have made a direct connection but now with st utility i cannot connect to st link anymore while before i can connect i need to change driver with zadig before try to reflash firmware. thanks
  7. Hello Rappelbox, I would like to order one 4. RGB DMD Display + Board assembled and tested 78,- shipping to Italy. I have only a little question:it is possible instead of cutting the plastic frame (it can be difficoult? coul you please post a photo of your work on it) to create a new support (made of wood or alluminuim) anf fix the display (after detach it from plastic frame) to it?
