USING THE SERIAL INTERFACE
The EA eDIP240-7 can be programmed by means of various integrated commands. Each command
begins with ESCAPE or HASH followed by one or two command letters and some parameters.
There thus are two ways to send commands:
1. ASCII mode
- The ESC character corresponds to the character ‘#’ (hex: $23, dec: 35).
- The command letters come directly after the ‘#’ character.
- The parameters are transmitted as plain text (several ASCII characters) followed by a separating
- Strings (text) are written directly without quotation marks and terminated with CR (hex: $0D) or LF
2. Binary mode
- The escape character corresponds to the character ESC (hex: $1B, dec: 27).
- The command letters are sent directly.
- The x, y coordinates and all the other parameters are transmitted as 8-bit binary values (1 byte).
- Strings (text) are terminated with CR (hex: $0D) or LF (hex: $0A) or NUL (hex: $00).
No separating characters, such as spaces or commas, may be used in binary mode. The commands
require no final byte, such as a carriage return (apart from the string: $00).
FILL PATTERNS
A pattern type can be set as a parameter with some commands. In this way, rectangular areas and bar
graphs for instance can be filled with different patterns. There are 16 internal fill patterns available.
character (such as a comma ‘,’) - also after the last parameter e.g.: #GD0,0,239,127,
(hex: $0A).
