CMOS level, low power consumption, and strong anti-interference capability. Large-screen display with the IrDA remote
controller can realize remote control easily.
2.12 Boot Switch
J8 is the system boot mode selection interface, shorting different jumper cap can realize different boot mode. The interface is
2.0mm pitch 10pins, the matching jumper cap in 2.00mm pitch.
E9 keeps all the boot modes. Please refer to the “Chapter Three: Development Platform BOOT Guide” for boot mode
selection. Here we list three kinds of boot switch:
(in the above picture, the right side is the first foot)
Note:
Make the Ethernet interface UP; J8 interface from left to right is 7, 6, 5, 4, 3, 2, 1 corresponding to the above table,
short the jumper cap is “1”
. X means connect or not connected.
2.13 LCD Interface
The FPC interface is 40Pin 0.5mm pitch down renovate interface. Its interface definition matches with all LCD display from
Embedsky. And it supports to select resistive or capacitive screen (capacitive screen by default), the touch signal is in the 37pin
to 39pin interface.
When soldering U20, R182 and R185, not soldering R175 and R188, it’s for resistive screen;
When not soldering U20, R182 and R185, soldering R175 and R188, it’s for capacitive screen;
R175, R182, R185 and R188 are all 0 ohm resistor, 0402 package, they are on the top left of the LCD interface.
