OUTPUT

Beginning with firmware V1.6 and the higher the EA eDIP240 is able to provide up to 7 digital output

for driving an external LED for example.

Depending on the choosen interface mode RS232, SPI or I2C all non used

configuration pins can be used as separate output lines. All lines used for output (open drain with

internal pull-up) are like 1=HIGH level for interface mode configuration.

Each output can be set by command ‘ESC YW n1 n2’ individually. Maximum current is 10mA per line.

Because of internal pull-up construction the max. current is valid for L level only. So theoretically each

line is able drive a LED direct. Larger current need to be amplified by use of a transistor or MOSFET.
