hi im working with picaxes and vb6 and i need to get the picaxe to display the info coming into the serial port and show it on a screen a bit like your pic logger. so far iv got vb6 to display the info into a textbox but what i really want is to display it into a listbox and seperate the info into 2 or 3 different items in the list. iv found out how to add items to the listbox, i added the word "AMP" but eery time i send it data it just makes a new item saying "amp" in the list but i dont want it to i just want the input data displayed next to the word "AMP" just like your piclogger i hop you understand what im talking about as i have a habbit of confuseing paople thanks in advance |

Hi jdearman What I need is a snippet of you code, and maybe a pic or screen shot of what you want. The PicLog sends a stream of data with some well defined area's. By this I mean, it uses a format thats easy to find the bit of the datastream you want. The picaxe chips sends the following example data. [<V>123</V><I>456</I><R>789</R><M>1<M>] The vb6 software looks for a [ and a ] as the start and finish of a data packet. It then looks for a <V> and </V>, and what ever is between these is the volts value, some thing happens with the other bits of data in the data packet ( I, R, M ). Its all done with what we call "string manipulation" Once you have yor bits of info you can then display it, which is where I think your getting stuck. List Boxes, like combo boxes and listviews, can be a little fiddly to use for the beginner. Check out google, try vb6 listbox as search words.

Hi sorry to bother you again glenn but i think i my have sorted it (i hope) anyway every time i try and program th pixaxe i get an error saying illegal character: ((oxffao)) here is my picaxe code: Start: SYMBOL RPM = W2 SYMBOL BAR = B1 Main: readadc10 4, BAR "THIS LINE IS THE PROBLEM" Count 3, 1000, RPM sertxd("[<B>", #BAR, "</B><R>", #RPM, "</R>]") goto main i have also tried programming with your std code and i get the same thing here isa copy of you code that i have Start: SYMBOL WSpeed = W3 SYMBOL RPM = W2 SYMBOL Amp = W1 SYMBOL Volt = W0 Main: readadc10 4,Volt readadc10 1, Amp Count 3, 1000, RPM Count 5, 1000, WSpeed sertxd("[<V>", #volt, "</V><A>", #Amp, "</A><R>", #RPM, "</R><S>", WSpeed, "</S>]") goto main |

I need to read my manuals, they are at home, but a couple of things worth trying. BAR may be a reservered word, meaning you cant use it as a variable, try changing it to something else like BARA. Also you assigned B1 for BAR, but thats only a 8 bit integer, and you use that on a 10 bit value from ReadADC10. It should still work, but the results may be unpredictable.
