Hi,

I notice that you also sent this question to our email support channel and that you have received a reply.

For completeness below is the reply that was sent:

Sorry that the pin number 32 (ACBUS 8 ) 33 (ACBUS 9) cannot be accessed under CPU-FIFO mode. if you want to access them, you need to switch the operation mode into the CBUS bitbang mode. but I don’t think it’s what you expected.
I suggest that you select async FIFO mode for your application due to it use the same HW bus as the CPU-FIFO mode but it works more efficient.
Due to the FT232H works as the slave device under the async FIFO mode, your CPU control the data access timing and it’s not necessary to inform the FT232H that the data transfer is done.

Please continue any further discussion with the email support channel.

Hello

Thanks for you suggestions regarding the API functions, I will certainly pass these along to the development team.

The datasheet and the Programmers Guide are currently in an update and review cycle. Once this has been finalised they will be released to the public.

Hello,

Our upcoming BT815/6 series of EVE ICs also include 1MByte of internal graphics RAM. However these new ICs include support for external flash memory which can be used to store/offload graphics elements such as images, custom fonts and widgets from the integrated RAM.
You can find out more about the BT815/6 at the following page:

Hello,

There should be no problems running the example code provided with the library.

Does the same thing happen on a different Windows PC?

Please ensure that you are using the latest version LibFT4222 Windows Library (v1.4.1) and Examples.

Mode 3 is the correct mode for using the device as 1 port for data stream (I2C or SPI) as per Table 5.1 in the FT4222H Datasheet.

You could try completely uninstalling and reinstalling the FTDI drivers. See FTDI_Driver_Uninstall_with_2-12-28_Install.pdf for details on how to do this.

Hello Stephen,

An example demonstrating 9-bit UART can be found at the following link (for the benefit of the community):

UART_9Bit_mode_example.zip

This should be included as part of the API in a future release.
