Matrix user forums

Hi, it has been a long time since i was here, so i am finding this forum a bit different. This area seems as though it is the only area i can post in so if it not the correct area i`m sorry...i`ts because i can`t post any where else. My problem is that i have tried to update my flowcode prof v4.2.3....

Thanks for that Benj , it works now. :mrgreen: But i have installed ppp v3 Twice in the same directory, but i can only see one instance, if i tried to uninstall them, it would uninstall only one! the ppp v3 would still be there! My concern is that i have 2 lots of ppp v3 in the registry and may cau...

Hi all , i am having trouble to get flowcode v3 to `compile hex` it returns an error message ..... Error: Failed to open:libc.pic16.lib or C:\Program Files\SourceBoost\lib/libc.pic16.lib failure Return code = -2 i have got flowcode v4 and v3 installed on my pc, but in their own directories. It look...

Hi all, it`s been a while since i last browsed here, too busy doing other things that need doing instead of flowcoding. :cry: i`m on holiday at the mo and had time to see what all of you have been doing . FLINT 3058 did a little program which you may like to have a look at, http://www.matrixmultimed...

Hi timo , this might sound a bit obvious but maybe you missed this. As the program only does one instruction at a time, and you are using your adc to cause a delay....a delay as in halting the program in it`s tracks....the rest of the program will also be delayed until the delay ends which then all...

Hi steve22, you ought to have a list of demo programs in your instalation of flowcode but you need to go through them one at a time as they are listed with a number. I have attached one of these demo files here, this one uses a switch to cycle through a number of leds , these leds represent an incre...

Hi echase, you may find this info of some interest, i found it on the internet a while ago, it shows the different
methods DAC can be done along with the pro`s and cons.

Hi all , just like to add that i have sorted the problem i had :mrgreen: , it was an integer variable that was not first initialised at the beginning of the program...i guess it was erratically first starting up with a negative number and having to work up to the `0` figure. Might be of something t...

Hi flint, i have just had a look at the great little program of yours that you sent me via `pm post`. Although i have no hardware to try it out on it is the sort of program that i would use so i have added it to my ` program toolbox `and even better, you have managed it without using `c` code. Well...

Hi walkover , thanks for the tips. I have a voltage divider setup using a 1k potentiometer to get a spread of 0v - 5v, this then supplies the ADC. I am supplying the servo from a separate battery. Yes i have the 100nf capacitor in place....with other capacitors as well. I can get a small test progr...

Hi benj, i am using 18F2620 and have ADC inputs on RA1 & RA2 , vref-, and vref+, outputs are on RC port.

Hi guys , can you please help with this problem?. I have got my pwm servo program to read 2 voltage inputs via ADC, the program generates PWM signal then the program adjusts PWM signal depending on the outcome of the ADC. Well, when i first start up the processor....ie. the actual hardware.....i ca...

Hi ondra, i thought i would go one better than my last post. i have put a demo simple maths routine together, dowload the program `mod` and just run it so that you can see flowcode variables.

Hi ondra, i used it in my servo program , this is what i used :

servo_val = ( servo_pos[port_counter] )
servo_l = ( servo_val MOD 3 ) * 85
servo_h = 31 + ( servo_val / 3 )

Hi flint, I have a couple of thoughts that you may be interested in. You mentioned you had a 10mhz oscilloscope, assuming this means you are able to read 10mhz signal and not got a max bandwidth of 10mhz ie. You need an oscilloscope rated 20 - 30mhz bandwidth, some say you will need a bandwidth 10 ...

Hi flint, Just one other point i would like to mention. As it is inevitable that you will end up using `C` code within flowcode, this renders the flowcode debugger pretty much unusable as the debugger does not read `C` code. So while your pondering about how to tackle your project, i would also have...

Hi flint , i`ll start off saying that i am no expert at this programing lark, but if i can help i will. I started using flowcode about this time last year. Great program to play with. A couple of questions. What kind of pic are you looking to use :?: . Are you using any of the matrix development bo...

Hi Flint3058 , seems we are both travelling the same path, i too am a Rc hobbyist, wanting to program my own controller, i have not come across any others in this field here in the forum....either they don`t post or don`t exist here.....it is a pretty quite forum on members chipping in....a bit dif...

WHOOO WEEE, i`ve place my order for one.
........my birthday coming up........the wife can give it to me...i`ll just give her the bill.

HI benj, To start off, i have found an extra ` output macro ` some where in my program, i thought it was deactivated by using the `mask` and unticking all bits, so now i have deleted this in case it made a difference...... Strangely it did :!: I have now re run the various variations using the ` ou...

Hi benj, i have been trying out the code but initially it did not make any difference but it is work in progress as other parts of the program need to be altered / removed which may be giving me the glitch, so i will need the week end to fully test out all variations before a conclusion can be made...

Hi benj, i have done a bit more digging, i have tried to clarify the program and my problem by changing the 5 pin outputs to use port `c` pin rc5, port `B` /0/1/2/4 , but NOT `B3` the ccp pin!.... This may be of interest if you think the ccp pins are involved. The purpose is to take the signal out ...

Hi benj , that`s a great find. I must say that does look a good bet. but i`m afraid this part is a bit over my head, but i`ll help any way you think i can. I have been playing around with my program, i have tried `setting` and `clearing` port bits with only `C` code that you gave, and placed them i...

Oh darn it..
Some how i thought that may be the case.

Hi icabjeff , i`m no expert but i was browsing through this forum as i have a problem in another thread that i`m hoping that someone will help with so i know what it`s like when your stuck and your left hoping that your problem will get sorted. Any way back to your problem, i believe what is happen...
