Ger UM1540 J User manual Opto isolated universal USB to serial bridge Introduction This user manual explains the functioning of the STM32F103xx based universal USB to serial communication interface UUSCI with opto isolated channels suitable for applications such as motor control boards directly supplied from the mains This user manual describes the functionalities present in the opto isolated UUSCI demonstration board and demonstrates how to use them The STM32F103xx microcontroller is used as the main digital controller to interface with the slave devices The system utilizes opto isolators to isolate the STM32F103xx and slave devices to control configure and monitor it The UUSCI has a 16 pin interface with which it is possible to connect a device which can communicate using SPI and UART Therefore the UUSCI tool allows the user to connect a serial communication based device to the PC It also allows at the same time some GPIOs available in that 16 pin interface to be controlled and set in input output modes as shown in the pin diagram In this demonstration board the STM32F103xx microcontroller is used as the interface between the PC and the end device Due to intelligence available in the STM32F103xx device SPI and UART are connected to the 16 pin interface Power to the board is provided from a USB mini B type connector In addition external target VDD T and GND T supply is used to power up the opto isolators output s
