RFM12BP on W7100 and Atmega32
February 15th, 2010Made a test with the RFM12PB, works great. First we have made a connection between two Kamami ZL15AVR boards. Sending three synchronisation bytes AA, a ‘magic’ word, and a string of characters. It is received by the other board without any problems. 434 Mhz, 134 Khz bandwidth. Without the power amplifier at this moment, we will test for distance later on. Code written in Bascom-AVR and we have to rewrite it for Bascom-8051, which has no function-command, to have it work on the other board, the iMCU7100EVB with the W7100 on it.


Add-on iMCU7100EVB
February 12th, 2010 This is the design of an add-on board for the iMCU7100EVB-board. It puts the LCD on a proper spot above the board and adds a RFM12BP module and a few switches. There is also an extra powerplug for the Power Amplifier of the RFM12BP. Working on the Bascom-8051 code for the W7100 to create a wireless connection. The RFM12BP is capable of generating 500 mW. FSK.
BTW, have seen it with my own eyes…. Mark Alberts is working with the W7100 as well!!!

First series of W7100 arrived…
February 8th, 2010Arduino and Servos
February 3rd, 2010Got some servos running with Arduino. The ServoShield is from www.renbotics.com and the servos from www.seeedstudio.com
The way to connect these servos is:
Red = +5 volts
Brown = GND
Orange = Signal
Connect a external powersupply to the terminal.

February 1st, 2010Bascom-code on Arduino ;)
January 31st, 2010If you want to use your Arduino Duemilanove with Bascom-AVR and program it from within Bascom, these are the steps you could follow:
Copy avrdude.conf to the root of your PC
Put your USB Serial port on COM3 (Control panel)
Choose within Bascom an external programmer and type at programmer the path to the avrdude.exe include avrdude.exe
And at the parameters type:
-v -F -Cc:\avrdude.conf -p m328p -P com3 -c STK500v1 -b 57600 -Uflash:w:{FILE}:a
Now you can compile your Bascom-AVR program and send it right away from within Bascom.


Arduino-code on Red Bokito
January 30th, 2010Arduino + Eth + Breadboard
January 29th, 2010Very easy to control a few LEDs over the Internet with the Arduino, Ethernet Shield and a Breadboard. Have used the same pins as on the Red Bokito so it also should work on this device. On the pictures: a hardcopy of the browser-screen, a picture of the full assembly and a picture of the breadboard.


Red Arduino?
January 20th, 2010Bought an Arduino Duemilanove and an W5100 Ethernet Shield a few days back. Very nice board and a very nice development environment. Lots of examples on the Internet. Compared the Red Bokito schematics to the Arduino in combination with the Ethernet Shield and found out that there was only one pin that needed extra attention, the reset of the Wiz810MJ. So with an
Int wiz_reset = 3;
pinMode(wiz_reset,OUTPUT);
digitalWrite(wiz_reset,HIGH);
I got the Arduino ethernet software running on the Red Bokito.
