Weblog Ben’s HobbyCorner

This weblog entry has been updated by the SMTPClient of the mBed

Well, got it working. An Arduino Ethernet Shield with a W5100. Without any modification to the hardware (also the INT not connected). Got to get used to that .NET Framework. Some strange things are happening. When a compile fails, the last good compile is put in the Netduino. So I made a blink-example, and after that a Ethernet example, but that didn’t compile well, so the blink-example kept beeing uploaded to the board. Will have to do a very good study of the C language that is used. Now several shields are working. LCD-keypad shield, Servo-shield and now the Wiznet ethernet shield.

An Arduino with a Atmel AT91SAM7X512 ARM processor. Getting a bit busy at the moment with .NET Micro Framework.

Won on ElektorLive, a LPCXpresso with LPC1114.

Nice combination if you get started with the mBed.

With the www.ge-th.com version 4 I/O board.

mBeduino Tweeting. And using the LCD Keypad Shield. I see different TextLCD.h files, there are .h-files with the R/W for the LCD used, and there are .h- files where no R/W is used, so you must skip that entry in the configuration of the LCD.

//works on the mbeduino…

#include “mbed.h”
#include “TextLCD.h”
#include “SDFileSystem.h”

TextLCD lcd(p12, p26, p24, p30, p22, p23, p11);
//           rs, rw,  e,   d0,  d1,  d2,  d3
SDFileSystem sd(p5, p6, p7, p8, “sd”); //p8 is the SD-card select

DigitalOut lcd_blanc(p25); //LCD_Blanc

int main() {

    lcd_blanc = 1;
    lcd.printf(”Bens HobbyCorner”);
    lcd.locate(0, 1);

    FILE *fp = fopen(”/sd/foo.txt”, “w”);
    if(fp == NULL) {
        error(”Could not open file for write\n”);
    }
    fprintf(fp, “Hello SD Card World!!”);
    fclose(fp);

    lcd.printf(”Sayonara World!!”);
}

mBeduino with Arduino LCD Keypad Shield…

This is the mBeduino. A baseboard for the mBed with RJ45, USB, power, SD-card, CAN-driver, EEPROM (I2c) and Goldcap. Bought one in Japan, it arrived as a DIY-packet. Took me half an hour to put all parts on it. It has also sockets for Arduino Shields. Got a working HTTPserver running at the moment. On one of the pictures the mBeduino with a LCD Keypad Shield from DFRobot.
