Hello! I currently have several questions regarding STM8500 + STLD1 DC carrier communication. Please reply!
1: I send differential signals via STLD1, which are capacitively coupled at high voltage between DC48V and DC48V_GND, then received at the receiving end. Shouldn't be any issues, right? The theoretical transmission distance can reach 3km, right? Is there a more complete reference schematic design available? The schematic provided in the official manual is incomplete.
2: The STM32F401 communicates with the ST8500 via UART. Can I use the ST8500 simply by calling AT commands or API interfaces? Or do I need to program the ST8500 itself or download firmware to use it?
