FT4232H_I2C connection

(1/1)

Arumugam:
Hi,
I could not find I2C application (schematics) with FT4232H datasheet.
Could you please review attached snapshot and let me know your comments.

1. I2C1 and I2C2 connection are OK ?
2. Can we use CD and DD bank pins general GPIO's ?

Thanks and Regards,

Hello,

Please refer to AN_135 MPSSE Basics which contains example circuits for I2C.
Please note that the I2C is a master only.

We also have Development Modules for test, evaluation and reference:

FT4232H Mini-Module
FT4232H-56 Mini-Module

Yes Port C and Port D could also be used for GPIO.
See the following application notes:

Bit Bang Modes for the FT232R and FT245R
AN_373 Bit-Bang Modes for the FT-X Series

Note that the bit bang/GPIO documents are not specifically for FT4232H but the same principles apply.

Hi,
Thanks for your support.
I have a query on the FT4232H bit bang mode.
I understand ports C and D can be configured as either UART or bit bang.
But if I want to use the bit band port as regular GPIO port,  what is required from software perspective? Can you share an example code?



Thanks and Regards,

Hello,

Example code of bit bang/GPIO is shown in the documents linked in the previous post.
