Posted on Tuesday, July 19th, 2016 in RF by DP m0xpd writes: I’ve been playing with a new RF generator for the IoT beacon… Actually, I do myself a disservice, because I’ve done rather more than just play with the RF generator. First, I’ve replaced the little USB to serial dongle which I used to program the original system and built a complete interface, using the same FTDI chip which was on the original dongle. The thinking behind this is to avoid the requirements for a clumsy interface to some of the more unusual UART lines (such as RTS and DTR), which are not taken out to the nice big header pins on a standard USB-Serial device. Then, I’ve changed the RF generator – moving from the AD9850 DDS module as used previously to the AD9834 chip. You can see the hardware here… More details at m0xpd’s ‘Shack Nasties’ blog.
