#168002 - USB-to-Serial, but "backwards" |
Yes, it's easy to get a USB-to-Serial converter that allows a UART interface to be connected to a USB Host.
But, just as PCs are rapidly losing their serial ports, now devices are also rapidly losing their serial ports - and coming with only a USB connection. So, what if I want to connect one of those devices to a microcontroller? Plenty of ARM7 & Cortex controllers now have USB Host ports, but they go on about hosting mass-storage or HID devices - I can't find anything that shows how to connect a "UART" class device. I think the Vinculum can do this, but the necessary firmware is only available on special request. So, any ideas? |
