Re: [Amforth] Serial interface at 115200 BAUD on Arduino Mega 2560

[<f.z...@me...>]

Tristan,

The DSO112A can be used in two ways:
a) as a stand alone mini scope and
b) as a module that can be integrated to user’s systems. Therefore on the DSO112A system board several connectors are provided.
One of the connectors is a alternative UART. It is a LVTTL connection.




I want to connect the Arduino uart1 (TXD1/RXD1) to this connector (J11).

From the manual: 
	The bit stream format for the serial interface is: 115200 baudrate, 8 data bits, 1 stop bit, and no parity. This is fixed and can not be changed
