DS1338-33 clock

Put a DS1338-33 clock IC on the board. It is the 3,3 volts 1307. 
Got some help to get soft I2c running, the command $forcesofti2c did the trick. And if you study the history.txt files of the Bascom-AVR updates, you will find this command.

WizFi210

HW part

HKipnik made an example how to make an UDP connection between the 7 inch display board and a Android SmartPhone.

Here some pictures of the WizFi210 with a DIY-antenna.

Wizfi210 5.jpg

Antenna, 31 mm, with an cap. Antenna, shrinked The WIZFI210 The WIZFI210 in detail

Config part

To configure the WIZFI210 with WPA or WEP key, with DHCP or fixed IP and to have it auto-connect a level converter RS232 from PC straight to the WIZFI210

Download the WIZSmartScript from the Wiznet site

The ZIP-file extracted Start the WIZSmartScript program, baudrate 115200 Find WizFI and Set Command Mode Do an Access Point scan and select the Access Point to associate with Select the WiFi security. In this case WPA with the Passphrase 'wisclub1' Give the module a static IP address (or if you want, give it a DHCP IP address) Here you can change the Serial port options For this example we will be using UDP traffic to a PC in our network that has the IP address 192.168.0.237 listening to port 5000 Select an save option. Here you create an startup profile for the WizFi210 module You enable auto connect on the next reboot and enable UART messages We saved it with the name benshobbycorner and here an example of a script

With a not programmed Atxmega128A1. Remove all four jumpers of the Alvidi module (RS232). The MAX3232 on the module will be isolated. Connect the TXD1 and RXD1 from the WIZFI210 to the second RS232 of the Alvidi module. Connect a terminal program, 115200 baud and power the board. If all is connected right you will get the information from the WIZFI210. Start the WizSmartScript and there you go.

SW part

For the next part, Bascom, Android and Wireless, all credit goes to HKipnik alias HKBascom alias Heiko.

First some pictures:

In this example the WIZFI210 has got IP-address 192.168.0.250

And my Samsung Galaxy Note II has IP-address 192.168.0.237

Port 5000 is used to send UDP-traffic from the 7 inch display board to the Android SmartPhone.

Port 8000 is used to send UDP-traffic from SmartPhone to 7 inch display.

All wireless.

Here the software for the 7 inch display board and for the Android Smartphone.

The first in Bascom-AVR and the second in Basic4Android.

In the subdirectory bilder, the images

In the subdirectory wizfi210 a small testprogram and some more info we got from Heiko.

What we did change was the touchscreen routine. We left the old one from Heiko remarked, and put in our own routine.

Seems there are different displays with different touchscreens.

File 1: Download 7inch_wizfi210.zip

File 2: Download Test_udp_wizfi210.zip‎

DHT11 sensor

DHT11 sensor on location JP1 and from www.AVRprojects.ru we have download software to read the DHT11.

Now we got the time and date from the DS1338-33 and temperature and humidity from a DHT11.

Time to make a WordClock. Fontsize 25x32. So on a 800 x 480 pixel display we can make 13 lines of 31 characters.

It is a running clock, the text is refreshed three times a minute so it is very dynamic.

In real the blue is less intensive.

iTrax300 GPS

The next step is the iTrax300 GPS module. It is the WIZFI210 or the Itrax300 GPS module, they are on the same serial lines.

Same trick to connect a PC direct to the iTrax300 module

Here the output of the module

Using a switch mode regulator

There is a switched mode regulator available which is pin compatible with the 7805 regulator and a similar size. The 7805 regulator is supposed to be roughly 55% efficient where as the switch mode regulator TSR 1-2450 is supposed to be roughly 95% efficient.

Due to the backlight of the display, the 7805 got warm/hot, with the TSR 1-2450 no problem.

Ben Zijlstra and Theo Kleijn designed the board and initial software.

HKipnik made various software extensions such as the WIFI.
