Sometimes I needed an external serial monitor like the Serial Monitor in the Arduino Editor, to see what is going on. So I made one.
\nThe first picture shows an example how could be it designed.
\nFor the ESM I used an Atmel Atmega328 (based on the Arduino-Board) because it have an internal SRAM with 2KBytes. It’s necessary for the big data processing.
\nSo you need more than 1KByte SRAM.<\/p>\n

With the menu in the ESM you can do…
\n… setting the baud rate
\n… start and pause the reading<\/p>\n

Step 3: Arduino sketch<\/h2>\n
esm.ino<\/strong>
\nThe main sketch.<\/p>\n
vars.h<\/strong>
\nGlobal variables are defined here.<\/p>\n
menu.h<\/strong>
\nThe menu-functions.<\/p>\n
buttons.h<\/strong>
\nThe buttons are here defined.<\/p>\n
programs.h<\/strong>
\nThe functions behind the menu.
\nmenu()
\nstartSerial()
\nsettings()
\nmode()<\/p>\n
myDOG.h<\/strong>
\nFunctions for the DOGS-102 display.
\nstatic void setChipSelectPin(PIN No. as const int)
\nstatic void writeByte(unsigned int)
\nstatic void Init()
\nstatic void begin()
\nstatic void drawPic(byte[8][102])
\nstatic void displayClear()
\nstatic void print(Text as char*)
\nstatic void print(Text as char*, Row as int)**
\nstatic void print(Text as char*, Col as int, Row as int)**
\nstatic void print(Number long, Col as int, Row as int)**<\/p>\n
** Col = 0 to 102 pix, Row 0 – 7<\/p>\n
myfont.h<\/strong>
\nFont definitions and functions.<\/p>\n
myPic.h<\/strong>
\nThe start image.<\/p>\n
mySPI.h<\/strong>
\nThe SPI function.<\/p>\n
Step 4: Example<\/h2>\n
The left homemade Arduino board contains the following code:<\/p>\n

\n\/ *
\nsender.ino
\nSerial Test Program
\n* \/<\/p>\n
void setup () {
\nSerial.begin (9600);
\n}<\/p>\n
void loop () {
\nfor (int a = 0; a <1000; a + +) {
\nSerial.print (\"int a =\");
\nSerial.println (a);
\ndelay (100);
\n}
\n}
\n<\/code>
\nThis arduino sketch is what I created to test.
\nThis program sends every 100 milliseconds a counter: „int a =“ 0-1000.
\nThe ESM (original Arduino board) is connected to the other Arduino via TX and RX (crossed).
\nNow you can press the play-button and it appears the transfer on the display.<\/p>\n","protected":false},"excerpt":{"rendered":"
