Having some difficulty with an FT232RL based board (CY232TOOL?) and an FT232AZ based board and an Adafruit Mini Metro.
So when the FT232RL is used as the USB/UART bridge to windows, the interface application can immediately detect the device has been connected. (The application has a "Wait Connect" mode, that waits for the device).
When the FT232AZ is used as the USB/UART bridge, the interface application cannot immediately detect the device until the mini USB connection into the device is well, wiggled, for lack of a better word. Rotating it clockwise then prompts the connection.
Ideally what I'm trying to do is use the Mini Metro with an application written on there to send the data without needing a PC at all. The mini metro has the same issue as the FT232AZ in that it only connects with some rotation applied to the mini usb cable side and - the connection is not maintained. More of a "flash" of connectivity, which is not enough time to write the intended packets of data.
Had assumed that the connection was "loose" on the device side, until the FT232RL board showed that it is not - and can write the data just fine. Have also checked the connections on the attached USB socket on the AZ board - also fine.
Sort of tearing my hair out a little bit here as to how these are different, and really don't know enough about electronics to know where to start.
