Hi,
Here is my problem: I have MODSOFT installed on my home PC, but i don't have a PLC. So I'm wondering if I could find some (free) software to simulate a Modicon Compact plc, or any other plc wich works with modsoft.
I also have concept, wich has its own simulator wich is cool, but i would...
Hello,
The simplest kind of temperature sensors are the thermocouples. Those are just two wires twisted together (not just any wires but special metals). Interfacing those to a PLC is easy, you just have to connect the two wires in the back of the controller. One good PLC for temperature...
By the way, melone, how do you configure the parallel port bidirectional on the 8 output bits? And I've heard that you can also use the 8 grounded pins as I/O. Is that true?
Problem solved.
It wasn't the ADC0808, it was my way of wiring the 373. Now everything works fine. My next challenge is a motion controller, the LM629. Hope to get over that too.
Thaks for everything.
Hi,
Thanks for answering. Today I plugged the 0808 directly on my BasicStampII (a little microcontroller) and it displayed the right value (linear from 0 to 255). So the problem isn't the converter or the way I've wired it. I will have a closer look to my program and my data transfering circuit...
Hello everybody, here is my problem:
I'm using an analog to digital converter (the ADC0808) in order to get position information from several potentiometers fixed on different shafts(it's for a robot arm).
I build the circuit and i'm using a program in C (made by me) in order to see the data...
