Hello out there, just asking for inspiration. I have a simulation which executes commands - everything ok. But now the program should also communicate with external hardware via a serial connection and that is the problem: - I don't want to block waiting for an answer since I also have a GUI. - Turning to file events I now have the problem that the simulation cannot continue before a partic...

In one project I have many quasi-fixed strings that I'd like to keep in non volatile memory (Flash) to avoid losing precious RAM space. static const char s1[] = "/my/very/long/string/of/01020304"; static const char s2[] = "/another/string/01020304"; ... Substring "01020304" is a serial number that changes during production with specific device. It has the same length in bytes (it's a s...

I have a proprietary device with a RS232 port controlled by a Windows application that opens a standard COM port. Now I need to move the device in a remote position with Internet connection. The user (and the Windows PC) will be in a different position. I want to develop an embedded Linux box with RS232 port connected to the device and Internet. I know there are many commercial solu...

Any opinions about FREE RTOS? I like a priority scheduling kernel for the product that I about to work on, but are there any significant issues or just annoying features? I am checking out the Free RTOS documentation and other resources. Just curious if anyone has experienced any undocumented issues with it. That's all. Ed

I often have embedded boards with a UART that shows debug logging messages. Most of the times, only the TX signal is of interest, in a few cases the debug UART features a full command line console, so both TX and RX lines are of interest. I have many UART/USB adapters and they work well when I have a desktop or mobile PC, running putty or Realterm or a similar software, near the devic...

Hello out there, I have a program that refuses to be handled by a pipe: - either it starts as a pure GUI app or - it opens a console of its own and accepts input only from there. So I thought of using TWAPI to feeding it my input but all the functions in the 'Console' section seem to handle the console of the calling process - at least none of the functions there take a HANDLE or HWND or...

Greetings: Found at a local dump: Huntsville Micro HMI-200-8096 -- Intel 8096 ICE with DIP pod and probes, no software or documentation. Avocet's website is devoid of operating documentation and ftp.hmi.com/ftp.avocet.com now rejects anonymous logins. Any old books, pdfs, old DOS/Win16 Sourcegate s/w, etc. would help a lot!

Do you know of some open hardware that runs officialy openwrt? I'll try to explain my needs. I have to develop a board that runs Linux embedded for a VoIP application. I need two Ethernet ports, LAN with active POE (where to connect a VoIP phone) and WAN (maybe with passive POE, where to connect a router). So, the IP traffic could be routed to the external router connected to WAN or, ...
