产品概要
描述
The STEVAL-PCC020V2 is a board with the purpose to interface a Windows® based PC with HVDPS products such as STNRG01x or STone. It is basically a bidirectional bridge between USB and I²C/UART buses.
The board is self-supplied through the 5 V coming from the USB port. An isolated DC/DC module is available in order to provide the correct supplies to the remaining devices. The board is also able to provide to the target device the requested VCC voltage in order to program the NVM or Flash parameters.
Communication between the interface board and the PC is managed by a standard USB to serial bridge, in this way the USB connection is converted into a virtual COM port.
UART RX and TX signals are then isolated thanks to opto-couplers and connected to an onboard STM32 MCU keeping the USB port and the remaining devices isolated from the mains.
The microcontroller is in charge of making the bridge between host UART and Target UART/I²C buses and protocols. (Dedicated GUIs are also available to handle STNRG01x or STone specific protocols and features).
The board also offers a dedicated connector able to support autonomous programming for mass production purposes (e.g. updating the NVM content using automation tools instead of a standard USB connection).
