I got a Cobra main board and a 7" LCD display yesterday. I managed to run theLED on/off program on the Cobra board. When I connect the LCD display to the cobra borad using the cable provides (of couse, power disconnected), it has stoped working the cobra board. When I disconnected LCD display, it worked again.
I used the 6V 2 A power supply, cobra board works fine without the LCD display. Can you help me please?
I followed the example given and talk to the display. I also tried your example for 7 LCD display. When the power is supplied to the main board, LCD display continuously refresh with different patterns. No response from the display at all when the display program is deployed and executed. I need your help to talk to the LCD display…Please
I’m having a similar problem with the 7-inch display.
I successfully loaded and ran the “configuration” application suggested in the display brochure.
I then loaded and ran the “GHI_Graphical_Demo_7in” project.
It immediately goes into calibration mode. I click [SELECT]. It displays the cross-hairs, which I click on. It progressively moves the cross-hairs toward the upper left corner, but then goes into a loop where it moves a small amount, then back again, and never finishes calibration.
