I set the dot in the device database for 2 UARTs and, basically, every '51 chip came up which, of course, means that 1 UART was enuf to show when 2 UARTs was selected. Erik
I reported this same issue to Keil a couple of months ago without much success. Sorry for that. I'm not sure how this issue was reported but this is the first I've heard of it. We make it a point to correct web problems quickly. I notice that Keil monitors the forum more intensively than emails directed to them! That's certainly not typical. Jon
