Hi there,
I'm working on a project right now where I have a serial data stream at around 4-6 kB/sec from sensors that are put in a wrapper with a checksum on it inside a micro-controller, then sent over serial to be logged somewhere.
Right now I am using a prolific USB to serial cable and find that under both windows and linux I am getting intermittent data loss at both 115200 as well as the slower 57600.
I have checksums in the wrappers so I can detect these errors, but I am disturbed by their frequency. Under windows it is impossible to get good data, while under linux there's roughly one error per minute. Still much too high.
Does anyone have experience with different versions of RS232 to USB cables/chips and whether or not the drivers for FTDI are better than this showing from prolific?
Thanks in advance.
