I☬ (Inter-Integrated Circuit), pronounced I-squared-C, is a synchronous, multi-master, multi-slave, packet switched, single-ended, serial computer bus invented in 1982 by Philips Semiconductor. Where can I find the project files ? 2 I☬ Bus: A PCB was made to facilitate a setting in box. But it can be used for another things like external lowpass filter commutation.ĭs1820 is planned just for fun, to send temperature by RTTY or PSK modulation. J1 connector could be dedicated for GPS input. You can find a pad space to experiment your own stuff and change bs170 to another transistor.

if gain value is too high bs170 may be destroyed. (put R3,C6,R4,L1 and strap J8) then apply analogWrite command on nano pin 6. – use SINB(J2) and apply voltage polarization on BS170 gate. Use any scope, you can find GND connection at PT5. When transmission is OFF QN voltage should be 0V. Adjust DDS 9850 trim to have a ~ « square wave » at the QN output. don’t put R3,C6,R4,L1, and left j8 open (this is the configuration i used). – use QN (J2) DDS output and replace C7 capacitor by a strap. The transmitter can be wired on a breadboard My last reports, not so bad with 0.1W Schematics: the simplest is to use a real-time clock instead GPS. The wspr imposes a transmission every minute even.

Synology surveillance station patcher how to#
You will learn how to program a DDS, make filters and setting of the transmission frequency. The idea is to learn how to build a transmitter without using an assembly ready to use.

The protocol was designed, and a program written by Joe Taylor, K1JT. It is a protocol, used for weak-signal radio communication.
