Summary of DISEQC TESTER CIRCUIT WITH ATMEL ATTINY13
This project is a DiSEqC Tester Circuit using the Atmel ATtiny13 microcontroller. It tests DiSEqC switches for protocols 1.0 and 1.1 across 4 ports, powered by a 12V supply. LEDs indicate proper input signaling by flashing sequentially, while continuous or no light signals faults. The device can output two 22 kHz tone amplitude levels (650mV and 300mV) to simulate challenging conditions like long feeder lines. It features short circuit protection with visual and audible alerts and cycles through port commands at 1 or 2 Hz.
Parts used in the DiSEqC Tester Circuit with Atmel ATtiny13:
- Atmel ATtiny13 microcontroller
- 12 V power supply (max 200 mA)
- LED indicators (for each controlled port)
- Resistors (current limiting and for LEDs)
- Capacitors (filtering/stabilizing)
- Sound indicator (buzzer or speaker)
- Short circuit protection components (likely fuses or current limiters)
- Switching circuitry for port control
- Signal generation elements for 22kHz tone output
This device is designed to help define the way DiSEqC-switches to the working protocols 1.0 and 1.1 and the number of entrances to 4 – x. It feeds the unit from the source of… Electronics Projects, DiSEqC Tester Circuit with Atmel ATtiny13 “avr project, microcontroller projects, “
This device is designed to help define the way DiSEqC-switches to the working protocols 1.0 and 1.1 and the number of entrances to 4 – x. It feeds the unit from the source of constant tension 12 V. For monitoring of correct inputs diseka used LEDs, which, if correct diseka must times a second switch, with only one to shine lights at any time. Permanent luminescence or nesvechenie one of the LED will indicate the failure sign. Moreover, it is possible to reduce the amplitude of parcels 22 kHz to 300 mV to test our diseka in difficult circumstances, such as long feeder.
