Any other device that needs to be USB-connected to PC, and has the RS232 port on the other side.These are the devices which are connected to PC via USB, and - on the other side - to the various hardware. These are service tools used by Phone repair centers and Car repair service. And the driver installed on PC creates the virtual device (usually, virtual COM port), which is used for communication. The mobile phones have RS232 or UART output, and PC may have USB only, the chip converts RS232 into USB. The most frequent usage is USB-2-COM interface. What is FTDI chip?įTDI chips are the chips which are developed by Future Technology Devices International ( ).įTDI chips are used in USB adapters to connect to RS232 and parallel FIFO hardware interfaces. The article also touches upon topic of FTDI chips EEPROM programming. The basic API set necessary for common operations is described. This article shows how to use FTDI API to interact with the devices, which have FTDI chip within. How to find out if the device is FTDI-based?
