I’m looking at using the GHI USBizi144 chipset for a new product I’m working on. So far it looks like it will work perfect.
The project would request the following modes of operation.
- PC-COM to COM transparent passthru @ 9600/38700/57600. - Mode enabled by PC-COM command
- PC-COM to COM protocol translator @ 38700. - Mode enabled by PC-COM command
- log COM data to SD card @ 57600 - about 2kb a second. - Mode enabled by Digital Pin State
- log COM data to SD card @ 57600, as well as transmit to PC-COM port. - Mode enabled by PC software connection status
While Modes 2-4 are active the device would have to read/write data to the COM port on I/O, AD pin values. - interrupt pins would be used.
The PC-COM port will be via a FTDI chipset as the PC software currently uses this chip with the FTDI D2XX driver.
Nothing is timing critical, all data logging would be raw data from the COM port. From what I have seen this project is nothing for the USBizi144 to handle.
I just wanted to double check that I’m not overlooking something before I submit my order.
Thanks in advance
