Re: [Gambas-user] About help and arrays and variables
I am following discussion on Gambas more than 3 months. Last 10 years I worked in VB6 (70%) and C(30%) on Windows.

Re: [Gambas-user] Did anybody try to run stepper motors through paralel port
To run a stepper we need 2 pins: one for direction: 0 is clckwise, 5V is CounterClockWise. Second pin is for stepping. I have to bring 5V and keep it for 200 nanosec or more with WAIT1 SUB then bring 0V, and then I need precise amount of time to wait. It has to be precise because speed of machine depends on it I have to wait let say between 100 and 1 microsec. If I wait 100microsec machine will move at 10 inch per sec which is maximum I need Here is how I do it in VB6 on win2000 (On winXP it is not smooth I feel machine will fall apart, and there is not help for this I try everything, only solution is WinXPembedded): == Public Sub WAIT1(w As Long) Dim kf As Long For kf = 1 To w Next kf End Sub == Public Sub WAIT2(s As Double) Dim c1 As Currency Dim c2 As Currency QueryPerformanceCounter c1 Do QueryPerformanceCounter c2 Loop Until ((c2 - c1 - overhead) / freq) s End Sub == 'run this at begining of the program to measure freq Public Sub OVER() Dim CT1 As Currency Dim CT2 As Currency QueryPerformanceFrequency freq QueryPerformanceCounter CT1 QueryPerformanceCounter CT2 overhead = (CT2 - CT1) / freq End Sub Public freq As Currency Public overhead As Currency == --- On Sun, 4/18/10, Doriano Blengino doriano.bleng...@fastwebnet.it wrote: From: Doriano Blengino doriano.bleng...@fastwebnet.it Subject: Re: [Gambas-user] Did anybody try to run stepper motors through paralel port To: mailing list for gambas users gambas-user@lists.sourceforge.net Received: Sunday, April 18, 2010, 11:27 AM Les Hardy ha scritto: Zelimir Ikovic wrote: I have VB6 program that run CNC plasma machine.

Re: [Gambas-user] Did anybody try to run stepper motors through paralel port
I wanted to know how predictable and reliable GAMBAS is when a reaction to real-world events is required. Let say that Java RealTimeSystem is intended only for suitable operating systems, which means that only a real-time operating system, such as QNX, is appropriate for implementing the JVM. So that means it depends on underlynig OS version ... Simply installing an RTS extension and renaming java.lang.Thread instances to javax.realtime.RealtimeThread will not turn the application into a real-time app. I just wanted to know what is Gamas reaction to real world compared under different underlyng OS.

FreeBSD, OpenBSD and Linux are not he same. I understand but, let me say, your sample code had nothing to do with realtime... it was simply fast as much as possible, without any mechanism to ensure some kind of real-time response to some event. To only read a counter is not enough. I can run 4 stepper motors directly (no step+direction, but driving the phases directly instead) with a CPU more than 100 times slower than a x86 CPU. But this is possible using interrupts. Practically every OS can, in some way, use interrupts - gambas can not. So, the only way in gambas to do precise timing is to let it run alone, with maximum priority and privileges. Or, to delegate high timing precision to some external piece of software (a libray or a driver) which can take advantage of interrupts, or callbacks, or signals. On the other hand I think that gambas can, with tight loops, do delays like you did in the original source. Surely it is predictable enough to let you calculate in some way the correct amount of cycling to obtain the needed delay - the fact is that gambas will never be the only thing running on the system, and you have little control about that. The same problem of windows xp - if you want precise timing, you must obtain privileges, either for the program or using a driver. I must also add that, without particular precautions, linux is more predictable about sleep() than win2000 or xp. Regards, -- Doriano Blengino Listen twice before you speak.
