FUNCTION OF JUMPERS

- “Disable Power On Macro“: If a continuous loop is programmed

either in PowerOn-, Reset-, Watchdog- or BrownOut-Macro, the

display is no longer adressable. In this case you have to restrain the

run of Power-On-Macro. This is done by the jumper: Switch power

off, set the jumper to the right (DPOM to GND). Now you have to re-

power the module and release the jumper or set it to the left (DPOM

is open).

- “Disable Protocol“: The small-protocol can be disabled. This might

be helpful espacially in the early stage of development. It is strongly

recommended to activate the protocol in series, to monitor data-

transfer. If the jumper is set to the left, the protocol is deactivated

(DPROT to GND). If the jumper is set to the right or left open, the

protocol is activated (DPROT open). You have to reset the module

if you want to change the protocol-mode.

- “Testmode“: Each eDIP includes a testmode, which can be

activated with the help of a jumper: Set the jumper to the left (TEST

to GND) and a test screen will be displayed. If you want to change

to normal operation you have to release the jumper or set it to the

right (TEST open) and reset the module.

FUNCTION OF LEDS

- “USB-Power“ (green): This LED indicates a connected USB-cable.

- “VDD power“ (green): This LED indicates the Evaluation board to be power-supplied

- “USB-TxD“ (red): This LED indicates data is transferd to the eDIP.

- “USB-RxD“ (green): This LED indicates data is send by the eDIP.

- “SBUF“ (orange): This LED glows if data is present in the sendbuffer of the display (SBUF low).

- “Output 1-8“ (green):

These

LEDs are directly connected to

the outputs of the eDIPTFT. They

are lit if the output of eDIPTFT is

set to high. The EA eDIP320-8

has no outputs, so this function is

not available.
