DIPDuino=(Arduino+ZigBee+OLED+SDCard+SRAM)*DIP32

I've compiled SDCard Info example with the updated OLED Display Library and it works fin, jut do't forhet to switch SS between the display and SDCard. Here is a sample code:

const int chipSelect = 23;

DIP_OLED oled;
char s[20];

void switch_sd_ss(void)
{
  //Select CS output to SD Card
  DDRB |= (1 << 4) | (1 << 5);
  PORTB |= (1 << 4);
  PORTB &= ~(1 << 5);
  delay(2);
}

void out_text(int x, int y, const char * str)
{
  oled.out_text(x, y, str);
  oled.display(); 
  switch_sd_ss(); 
}

void setup() {
  oled.init();
  oled.clear();
  out_text(12, 10, "SD Card Test");
...

I am updating DIPDuino libraries and making it compatible with Arduino 1.8.0 IDE

Here is DIPDuino OLED library packaged for Arduino IDE: dip_oled.zip

... and some sample code:

#include <dip_oled.h>

DIP_OLED oled;

void setup() {
    oled.init();
    oled.display(); 
}

If everything is good , you'll get this result:

Here is DIPDuino driving two 64x32 RGB panels over HUB interface. I am getting so much help from DIPDuino when building my prototypes.

I 've made a small batch of DIPDuinos for sale. You can buy your own DIPDuino for $69.95 USD. Quantity is very limited. Please write me a message if you are interested. Your help and support is very appreciated!

Simple Humidity and Temperature data logger implemented with DIPDuino and DHT11 senor.

Both, temperature and humidity logged to SD card. There is no RTC yet, so no time-stamps.

Next step is to implement data transmission over ZigBee.

DIPDuino+Radar Transceiver = Radar Gun + Logger

Using DIPDuino in my research project:

Work is completed on OLED library for DIPDuino (dip_oled.h). Library is now available for download at DIPDuino.com.

Also, I've redesigned DIPDuino's body. Body version 2 snaps on PCB while previous version must be glued. At the same time I made couple of adjustments for better fit:

New version of DIPDuino has four more ADCs inputs. New schematics is available on DIPDuino.com website and new pinouts diagram is published above. New PCB and Ardunino headers will be ready in few days.

Updated DIPDuino's Schematics (version 2) is available for download at DIPDuino.com:

Updated pin-outs and Arduino headers coming soon.
