Discussion - Hardware / continuous clock?
« on: February 04, 2019, 11:56:18 AM »
Is there any way to set FT2232H to output continous (stable) clock on SCK pin? I would like it to execute MPSSE commands on top of this, synchronized to the SCK edge like normal, shifting in and out on active CS only.

Thanks, but I want to be able to support several of these FT2232 devices attached to the same computer, so I need to identify the ports belonging to the same device. If the driver can't not do that, I guess I need to add a hard link between an IO of each port, but I honestly think this is a job for a (future) driver. I'm pretty convinced there must be some linkage to the common usb port handle somewhere in the operating system, that the driver could pick up.

My application is a "bringup device" to initialize products during factory initialization (to talk to both SPI and serial), and I want it all to be automatic and work with several bringup devices on the same computer.

Is there a safe way to identify two(four) MPSSE ports belonging to the same FT2232(FT4232) chip? In my case I wanted to write software for a specific custom made hardware device containing one of those chips, and in the case there should be more than one of these FT devices connected to the same computer, I need to identify which ones are belonging to the same device. I know it can be handled with serial numbers, but let's assume the serial is not written to the EEPROM.

Is there a way to force these signals in a default state (provided handshake is set to none)?
I know they can be programmed, but I'd like to pre-set them while running standard serial terminal software.
