Made 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.
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!!!
Got 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.
