This device is based on ATtiny13A with closed-source firmware with author's features. It is not DS2450 or its replacement, but it is developed to be possible to use it with a lot of software written for DS2450 (such as OWFS or Linux kernel modules).
- digital/analog sensors read
- mosfet/relay control
- alarm systems
- communication
- 5 true GPIO ports
- device can continuously watch for certain logic state on all ports and set alarm flags
- 1 port with PWM function
- 4 ports with ADC function (up to 12 effective bits)
- device can compare each ADC result with 2 thresholds and set alarm flags
- 1-wire slave to SPI-master bridge
