Help ME Drive SSD1963
« on: August 30, 2017, 11:54:26 AM »
Greetings~
I am involving in an electronic project--make a set of control board. The MCU is 103ZET6 while the driving chip is SSD1963 amd the screen is AT070TN92. However,I don’t know why the screen can’t be lighted?
This is the circuit:




Are there any wrongs in the circuit?

If "lighted" means that the backlight LEDs aren't on, the error is probably in the software. The circuit connects the PWM output of the driver to transistor that controls the cathode of the LEDs.
If you need more help provide links to the datasheet of the driver chip and the source code.
