Figure 7.7 Dual LED Configuration

An example of using the FT231X to drive LEDs is shown in Figure 7.7. In this application one of the CBUS

pins is used to indicate transmission of data (TXLED#) and another is used to indicate receiving data

(RXLED#). When data is being transmitted or received the respective pins will drive from tri-state to low

in order to provide indication on the LEDs of data transfer. A digital one-shot is used so that even a small

percentage of data transfer is visible to the end user.

Figure 7.8 Single LED Configuration

Another example of using the FT231X to drive LEDs is shown in Figure 7.8. In this example one of the

CBUS pins is used to indicate when data is being transmitted or received by the device (TX&RXLED). In

this configuration the FT231X will drive only a single LED.
