Re: help connecting tft screen from dvd player

Just connected the display driver to the main board. Got the same black screen. What should I do next?

The pcb connects to the lcd so I'm pretty sure that they are the input pins.
The pcb is the one on the second photo.

Re: help connecting tft screen from dvd player

Tried feeding video through all pins except the rem pin but it doesn't work. What does the rem pin do?

Re: help connecting tft screen from dvd player

I think that the display driver uses s-video input. The tv/c pin is color and s_y is image. If I connect the two pins to the composite out of the RPI it will work.

Re: help connecting tft screen from dvd player

Just tested the inverter with the screen using my 2.5 amp 12v power supply.
It works :D
Now time to start with the display adapter.
looks like it even does not need 5v on the chip enable pin to activate it.
All I know is that this dvd player is from sony.

Re: help connecting tft screen from dvd player

Ok guys. Yesterday I checked the ic on the display driver. Now I checked the inverter ic and found the datasheet for it. I found that the two pads on the pcb lead to the ic. One is a power input and the other is chip enable. The input voltage is from 6V to 17V. I plan to use it as a screen for th RP...

Re: help connecting tft screen from dvd player

the inverter generates a high voltage for the indecent gas tube for the LCD backlighting, on the input (if there are only three wires) I guess would be one ground wire, (probably originally black) one power wire (probably originally red and for 12V) and one wire for "control" that is either on/off ...

Re: Need help controlling brushed ESC

When I was trying the ESC with arduino, I didn't do any initializations. And I don't think in needs one, because this ESC is used in only RC cars.

Re: Need help controlling brushed ESC

Just tried "pigs s 4 1500" after installing pigpio, and the motor started beeping.
Tried playing with the last number, the beeps were changing or completely stopping.
