DSC01487.jpg Open4x9i-c turned on with LCD_7inch demo loaded. Notice just white screen. DSC01491.jpg Logic capture of DE, B2 (Blue 2), R0 (Red 0), G2 (Green 2), Vsync, Hsync and Dclk connected to Open4x9i-c LCD 4.3inch connector LCD.P1 Image shows 1 frame of just the red backdround of the LCD_7inch demo and 2 frames of the start of the white box before the message begins. DSC01490.jpg Expanded frame showing white box with black message. DSC01489.jpg Terminal showing initialization and one finger touch of Touch_CAP_LCD7 demo. No change of LCD display, still white. DSC01493.jpg Keil uVision 5 screen with Touch_CAP_LCD7 demo built and downloaded. note: **Dclk is between 8.33MHz and 10MHz or 100ns to 120ns duty cycle. Hsync is 23.5ns. Vsync is 11.4ms. DE is enabled 17.860us +/- as is a solid color of maximum value. **note 2: Due to USB bandwidth limitations the logic capture shows uneven space in pulses. I am not certain the timings are correct but the video and signals are in good form. I did use a DVM to verify the pins continuity from the Core4x9i board to the 40 and 50 pin connector on back of the LCD070. All are good. Pressing reset does not change the video. Still white. Pressing up to five fingers on the screen does report the five to the serial terminal using the Touch_CAP_LCD7 demo. No change on screen. As one image shows I am using Keil uVision 5 to build the demos. As I stated in my first email, so far every device I have tested works, but not the LCD. If you make available to me the two LCD demos in HEX (built) format I will try them.
