Hello, I would like to announce my new device originally based on selfbus, which I've ported to STM32 platform.
I've designed a custom STM32-based board but one can use a STM's Nucleo development board as well. Bus-coupling interface is quite simple because of STM32's built-in DAC (threshold ...

Re: Simpler bus coupling design
I have two ideas to simplify TX and RX:
1) Use STCS05A https://www.st.com/resource/en/datasheet/stcs05a.pdf as 0,4A current-limiting TX switch. So the TX would be STCS05A (1€) + 4148 diode + 7V5 zener diode (dropping bus DC voltage by 7V, as specified for TP1-256 Transmitter).
2) Use MCU with ...

Simpler bus coupling design
Hello,
I'm new to this project and I like it very much.
I would like to design a simpler (may be not necessary as much KNX compliant?) transceiver design.
Is the circuit explained more in detail somewhere? If not, I put some questions here:
1. What is the purpose of the 150mH inductor? Does it ...
