1. General description
FT245BQ-REEL provides a simple, cost-effective and efficient method to transfer data to peripheral devices and host P/C. in To 8 million bits per second (1 MB). Its simple FIFO-like design makes it easy to connect to any microcontroller Or the microprocessor through the IO port. To send data from the peripheral device to the host, you only need to write byte-wide data into the module when TXE# is 0. low. If (384 bytes) the transmit buffer is full or is busy storing previously written bytes, the device will keep TXE# high In order to prevent further data writing, until some FIFO data is transferred to the host via USB. After each byte is written, TXE# becomes high. When the host sends data to the peripheral device via USB, the device will set RXF# to low level so that the peripheral device knows At least one byte of data is available. Whenever RXF# goes low, the peripheral can read a data byte. RXF# becomes high After reading each byte. By using FTDI's virtual COM port driver, the peripheral device looks like a standard COM port of the application software. The command to set the baud rate will be ignored-the device will always transmit data at the fastest rate, regardless of The baud rate setting of the application. In addition, FTDI’s D2XX driver allows application software to access the device It is done "directly" through the released DLL-based API. Details of the current VCP and D2XX drivers can be found on the FTDI website
