Posted by Marc H in MSP430 on Apr 23 2013
Hello... I'm new here and to the MSP430 as well as Uc's in general so please be patient. I have gotten a launch pad and a couple of different Uc's to start using and I have been trying to familiarize myself with some concepts before I do something stupid and ruin some chips. I see on the data sheet that the devices @3.3vdc will output a signal that is TTL compatible but I cannot find any ... MSP430 TTL Compatibility at 3.3V

I can't quite believe i'm having this problem! i'm a professional software/hardware developer but not in the GCC/Arm world. I'm a real newbie in GCC but have C experience on other platforms. I'm so stuck...but I suspect it must be something very simple. I have a very basic GCC program that can't access any of the standard functions. I'm targeting a philips LPC2129 ARM7 processor. I ri...

TCP/IP using gateway not working.   [3 Articles]

Posted by dirk_the_stryker in Rabbit-Semi on Apr 19 2013
I use BL2600 single board computers for data acquisition. I then use a Visual C# program to connect to the boards and analyze the data using a tcp socket connected to the BL2600. The BL2600 acts as the server using tcplisten(). The software connects to the BL2600 just fine over a local network. However, if I try to connect remotely through a gateway, it will not connect. I can ping the IP addr... TCP/IP using gateway not working.
