Discussion - Software / Can someone please explain how event characters are supposed to work?
« on: February 16, 2018, 11:24:07 AM »
Hello. I'm using the FTD2XX.dll to interface to a FT232RL chip and was noticing some odd behaviour. I've turned on event characters and when I send a series of packets that are exactly 62 bytes (including the event character) then there is a very long delay before the data is available to my application. I've read application note AN232B-04 a few times and this behaviour makes sense if I don't have event characters turned on, as the rate I am sending data back and the value of the latency timer means data wouldn't be sent until the USB buffer is full. But as I have event characters turned on shouldn't the USB buffer be flushed every time an event character is seen in the data stream, or have I misunderstood something?
Many thanks
