    C18 how to manage pointers

    Hi again, Thanks for your cooperation and problem solved. In C18 is not possible to assign pointer's value to a variable. In the code above I had: startostring2=string2; -->Error startostring is a ram variable who retain the address contained in string2 (a pointer). Even startostring is a...

    C18 how to manage pointers

    Hi, due to my work, recently I moved from CCS to C18 and everything ok, except for one thing: I dont know how to manage pointers in C18. Time ago I built a string search routine who worked similar to "find" python instruction. So, I wanted to use it now, in C18, but I have -- Error [1131] type...

    Microchip MPLAB c18 Build problem

    Hi, Hackdrag Hope this help with your problem, if it still exists... be sure of this in your main code: #include <p18f14k50.h> don't write as "p18f14k50", because quotes says to compiler "look for in the project folder, only". So, if you don't have p18f14k50 in this folder, an error will be...

    Short version of help for the ICD2

    for dgs117, ICD2 version of Lothar Stolz uses a FT232BM to emulate an USB port, but it isn't one. FT232 firmware creates a COM port to comunicate with MPLAB. That's why velocity is limited to 57Kbps. Really it is a COM port and not an USB. So, version of Lothar Stolz is really a serial ICD2.

    300 POINTS FOR good idea

    Hi Well, I can't help you totally but I think I can give you some help, because time ago I made a similar system using a voice rf link on radiocomunication equipment. My idea was similar. I will send over a voice channel dtmf tones to represent digital data. On the reception side, I took the...

    What do you think about this GPS module?

    Hi BlackOps your module is ok. Good sensivity, low voltage and tiny, but too much connector and needs an external antenna. Also you need a line transceiver (max232 or similar) to connect to pc, because it has TTL levels. By the price, I preffer this from sparkfun...

    LCD display problem in the code

    Re: LCD Display Problem hi The problem is that after you prompt "enter code", the pic returs quickly to scan what happen on its ports. And well, press the enter buttom, to human, takes a little time, let's say a few miliseconds. So, when pic returns to scan their ports, enter buttom still...

    Schematic and PCB for USB to RS232 converter

    ft232 max213 Hi men, Ft232 is a good IC to make an embedded usb port, but still need to much external components. Try with this: CP2102 from Silicon Labs. No external components needed and it's very easy to configure. I bought a few from RS components. datasheet: **broken link removed**...
