stm8s003f3 433mhz EV1527 write firmware -- 2


i am re-posting this project.

I have a portable wireless receiver (reciever only) which has buzzer, speaker, leds, switchs, and 433MHZ receiver.

i need this device to be able to "learn" a signal, and alert if detected.

the signal is based upon EV1527/RT1587E protocol (20 bit address + 4 bit data).

i added files for more information.

One thing we could not find - is how to measure VDD voltage, as it need to alert on low battery.

Thank you.
