What says FT_DEVICE_LIST_INFO_NODE type?

(1/1)

radimoid:
Hello,
in my app, I would like to recognize the FTDI chip type (FT232H vs FT245R). Can this be done by checking FT_DEVICE_LIST_INFO_NODE type? I didn't find any documentation to this struct member. I have just recognized that FT232H has set its value to 0x08 and FT245R to 0x05. Is this general rule? Is there any documentation of type codes?

I know that the type could be also recognized from eeprom product id. But this can be reflashed to any value (as it happened to me once).

FTDI Community:
Hello,

Yes that is correct. Please refer to the D2XX Programmer's Guide:

FT_DEVICE (DWORD)
FT_DEVICE_232BM = 0
FT_DEVICE_232AM = 1
FT_DEVICE_100AX = 2
FT_DEVICE_UNKNOWN = 3
FT_DEVICE_2232C = 4
FT_DEVICE_232R = 5 (also includes FT245R)
FT_DEVICE_2232H = 6
FT_DEVICE_4232H = 7
FT_DEVICE_232H = 8
FT_DEVICE_X_SERIES = 9

Thank you for the reply. One more question. Is there any way how to distinguish 232R from FT245R. FT_PROG application can distinguish between them. But I'm curious how can this be done from my app.

FTDI Community:
Hello,

This information is proprietary to FTDI.

You can read the product description to determine the product type.
The default product descriptions can be found below:

FT232R USB UART
FT245R USB FIFO

The other option you have is to program a unique serial number or description to help you distinguish between the two device types.

Ok. Thank you for info.
