We are using FT2232hpq module  and We are using "MPSSE" mode(SPI) and is it possible to operate the GPIO0(56-pin),GPIO1(55-pin),GPIO2(54-pin)  and  GPIO3 (5-pin) pins in software.

Hi,
just to report informations about some tests I did (after a long pause on my FT260 project..) on a small dev board. I put a UMFT260EV1A on it, with a MCP23008 I/O expander connected to 4 buttons and 4 Leds and I connected the MCP23008 INT pin to GPIO3 (INTRIN/WAKEUP) of the FT260.

I had to activate the two HID ports, for I2C & UART, because with only the I2C it wasn't working.. (so the DLL is really using the UART to read the interrupt flag)

so, from LibFT260, I used FT260_UART_Init, FT260_SetInterruptTriggerType, FT260_SetWakeUpInterrupt , then FT260_I2CMaster_Init.
after that I send the config to the MCP23008 to activate the interrupt in open drain mode when I push a button.
and then I could use F260_CleanInterruptFlag to see if an interrupt occured and set a Led ON. and it worked ! 

so the Interrupt flag can be used.

Hello All,

LibMPSSE 1.0.5 fixes all known issues and is available on our website:

Hi,

We don't have any references for doing SPI communication using Bit-Bang. I would recommend that you use the MPSSE for SPI communication instead.   

To use I2C/SPI as a master (no slave functionality), see AN_135 MPSSE Basics and our existing MPSSE Example projects:
 
MPSSE Examples
 
There are two options to use I2C/SPI modes with the MPSSE engine:
 
a.   Use LibMPSSE libraries. Example code is provided with the download. Source code is also provided.
b.   Use D2XX drivers direct. Example code is shown at I2C / SPI. AN_108 Command Processor For MPSSE and MCU Host Bus Emulation Modes provides the necessary information.
 
Option b is the best option to use the D2XX drivers direct (no dependency on libMPSSE library).

Also please also note, SPI modes 1 and 3 are not supported with our MPSSE engine.
So please check that your SPI device doesn’t work with these modes.

You can find all the referenced documentation above, here

Hi Joseph,

All of the formats supported by FT602 can be found on page 13 of the FT602_UVC_Chip_Configuration_Guide.

There are no signals like VSYNC/HSYNC/PCLK on FT602. FT602 is connected via an FPGA.

You can refernce the FT602 example code, which you can find here. The example code shoes YUV only, but you can use it for a reference for the other formats.

Hello, I want to set up SPI communication on a Linux Jetson kit using the FT4232H chip with Bit-Bang. First, I installed the necessary structure, and I can send data properly via SPI using FT_Write. However, I encounter errors when reading incoming data using FT_Read. Also, the reading process takes a long time when I clear the FIFO each time with FT_Purge. What would be the best method for reading data over SPI? How can I read the MISO pin accurately at each rising edge of the clock signal for SPI?

I would like to inquire whether it is possible to change to UVC using the video format YC16BIT and VSYNC/HSYNC/PCLK on FT602Q.
If possible, can you tell me the port pin map that I can input?

Hi,

yes, FT2232H is a high-speed device. The driver can only operate with 1ms latency minimum.

Yes I've done this and it is a little faster than set_latency_timer(2).  But doesn't this device support high-speed USB (480Mbits/s)?  Or does it only run at full-speed (12Mbps) for I2C transfers?

Hi,

You can try setting the latency timer to 1ms. This will make the device ran as fast as it can.
