Having had a search around the forums here, I gather that the general opinion of the FTDI USB chips is that they are pretty good.
If the salesman is to be believed, using simple RS232 at the microcontroller end and their driver at the PC end, bidirectional comms miraculously occurs and I never need to worry about the USB transport mechanism.
For an application we have, we need to keep about 4Kbytes of data in synch between an embedded micro and a PC more often than roughly once per second.
Notwithstanding the fact that we have to implement a protocol to achieve the synchronisation (my problem, I realise) are these chips really up to the job?
How about if somebody else has a device using the same technology? Is their driver clever enough to be able to address MY device rather than the other one?
Thanks for advice in advance.
