I don't see where the program can display the data from two ports at once but that brings up an interesting idea. If I take a microcontroller with at least two hardware UARTS, I can hook two of the UART data-inputs to the bidirectional serial connection under test and then output the two streams to ...

Can that one be used between two microcontrollers or is it just for communications that are going in and out of a PC?

RS-232 serial protocol analyzers

I am thinking of investing in a serial analyzer (hardware or software) and I am wondering what other people are using. Nothing I find really seems to spin my crank. I am hoping to spend less than $250, if possible. Free would be even better. Would like to avoid programs that have annual license fees...

Hmmm...

On first glance it looks like a bouncing contact isn't very compatible with how the interrupts work with either of these chips.

Or am I misinterpreting the spec sheets?

Thanks guys. I'll research both suggestions.

I am trying to save the I2C connection for a mess of sensors so I am not sure I want to put mission-critical control switches there as well.

You can tell that I am treading in new territory here!

Question about muxing button & switch inputs

I have a need to mux together up to 16 digital inputs, made up of pushbutton switches and some toggle switches. I also want to add debounce and the ability to trigger an interrupt pin when one of the switches changes state. So far I have been looking at the HP4067 A/D mux, the Max6816 debouncer and ...

Re: Arduino Mega2560 board => ZBasic

Is it possible to use the ZBasic compiler for [the Arduino Mega2560] board with a Generic licence? Yes, it is. The Arduino Mega has a 6-pin IPS connector like many other Arduino boards. You can use this connector to program the bootloader or you can use it to program the application if you don't wa...

There is also the possibility that there is an error on the circuit boards that does not show in the logical schematic.

Hang in there! RTFM replies are not appropriate here and I don't think that Mike intended for you to take it that way. One fun option would be to get a Parallax BOE-Bot, Parallax LCD AppMod and a ZX-24r. There is Zbasic source code here that will help you to communicate with the LCD AppMod and we'll...
