The USB-C connector was developed by the USB Implementers Forum (USB-IF),... During USB communication, data is transmitted as packets. Initially, all packets are sent from the host via the root hub, and possibly more hubs, to devices. Some of those packets direct a device to send some packets in reply. After the sync field, all packets are made of 8-bit bytes, transmitted least-significant bit first. The first byte is a packet identifier (PID) byte. The PID is actually 4 bits; the byte consists of the 4-bit …
WebAug 22, 2024 · The basic concept is: because USB-C is no longer directional (previously you always had USB-A on one end and USB-B/mini/micro on the other end of a cable, it was clear which side was providing the power), a USB-C charger is not supposed to provide power (not 100% correct, I think the charger still provides 5V, but limits the current) unless … WebThe MCU communicates with the serial adapter using a serial protocol (such as TTL) through the UART interfaces of both the MCU and the adapter. The UART data is then translated to the USB interface on the chip by its internal hardware (and firmware since I'm assuming there is a MCU in these modules).
