SC16IS750 I2C/SPI to UART Bridge Module. UART data contains a start bit and a stop bit bracketing each byte, so for each 8-bit data byte you want to transmit, you need to put (at least) 10 bits into the SPI data stream. The device provides a UART serial port that may be controlled through an I2C or SPI port. SPI Then we initialize SPI module.Then the code is to check whether there is data coming to UART module and if so,just relay them to SPI module.The last line will send received data again to another UART receiver via UART Tx pin. : BRT#078 4 Using the GUI A Java-based GUI application is provided with this Application Note as an example of how the UART to SPI Bridge can be used.

This Application Note describes and explains the FT90x UART to SPI Bridge. A PLL and fractional baud-rate generators allow a high degree of flexibility in baud-rate programming and reference clock selection. SPI data is normally MSB-first, but UART data is normally LSB-first, so you'll need to reverse the bit order in each of the data bytes. The SC16IS750 is a slave device to the mbed controller. Hence you will need 16-bit mode in order to transmit the 10 bits required by UART. You will have to ensure that the UART transmitted baud matches that of the receiver. : BRT_000130 Clearance No. The USB to SPI Bridge uses a single channel USB 2.0 Hi-Speed to UART/FIFO IC.
