A few days ago, I received a book called "MCU Engineer's Refining Notes" which I got from updating my information. I have read it all except the part related to MSP430. I think it is well written. Goo...
I recently came into contact with MBUS, which is used in meter reading. I looked up its information online. It seems that the host sends a voltage signal, and the slave sends back a current signal. I ...
