Hi,

The schematic of led is not clear. I assume your are connecting the anode to ft232rl and kathode to ground. If so it will not work. The LED should sink not source. Otherwise just check your hardware with a continuity meter. If that too does not work then reset the settings of the device by using the utility provided by the manufacturer.

hi
have you used this configuration to connect LEDs?

and you may want to check the configuration for CBUS pins as described in section 3.5 (the default config is CBUS0 for TxLED & CBUS1 for RxLED)

Shihab is right

must be common anode...?
I put on common cathode, perhaps that's my mistake ?
