Hello Guys,
I know its a very old thread but I thought about sharing my experience might be useful for someone one day.
First thanks for all your replies.
To use the DLL file with any windows application you have two options:
- copy the .dll file(s) to the project directory.
or
- copy the...
Hi Guys, have good news :)
found two libraries you can use to interface PIC32 with 2x16 LCD display here: http://jonsson.eu/programs/ansic/dogm16x/
and here: http://www.opensourcepic.com/LCD.php
may be you will need some header/.c files from Microchip applications libraries, so download and...
I have tried to use it already and didn't work fine with PIC32 cause of clocking and timing issues, its more optimized for PIC18F.
Anyways thanks for your reply.
Hi
I need a ready 2x16 character LCD library for PIC32 microcontroller, most of the libraries I have found are designed for PIC18 and PIC16 microcontrollers product families but didn't find yet something for PIC32, the recent library is only for graphical based LCD which is too fancy for the...
Hi guys
After 9 months of this post I have discovered this library and completed the project, the library called DISLIN, free to download, with C++ and Python wrappers,
DISLIN
Enjoy :)
Ok, got from other forums that I should used read/write data to sectors of the PIC18F4550, and I can't use the FSIO.h API's like FSfopen, FSfclose,...etc,
so, does anyone have an idea of how to write to sectors of the internal flash, known that FAT16 file system is used, and how this will be...
you can use CDC class, so it will be so easy to interface using the usual COM port API's.
regarding real-time issue, yes, I agree with you, USB isn't that good for real time applications.
Thats was my point from using a resistor, which I cleared in my second post, however some of the MCU are already designed with internal elements to prevent this as I mentioned before, which already worked out with some people, frankly I like easy designs and minimizing the number of components...
Dual H-bridge: 2 H-bridge circuits inside the IC.
driving the bipolar stepper motor coils requires to invert the polarity of the applied voltage on the coils to move the motor, so the H-bridge will give you this.
this IC (L298 ) is capable of handling up to 2A current, so my opinion don't use...
thats why I suggested the idea of an RC low pass filter, the resistor will act as a current limiter, thats in case the microcontroller hasn't any current limit element connected to the PWM output, regarding the idea of 2nd or 3rd order LPF with a buffer, its good one but will add more...
Hi all
I have one of posts someone was asking about creating a variable analog signal inside a digital system, where i got couple of ideas about "how to create analog signal for your digital system":
- if your microcontroller has a PWM output then you can use to create an analog signal by...
you can use PWM output from the microcontroller to create variable offset, just you will need to connect a smoothing capacitor on the PWM output to get a smooth pure DC signal, the calculation of the offset value will be proportional to the duty cycle value which you can calculate.
let me know...
also you should consider the interfacing with the PC issue, its not easy to interface CAN bus to a PC, and for sure you will need a converter to convert from CAN to any standard PC interface like USB, if you aren't working in huge field and distance between sensors and PC and quite small (few...
I think its better for you to use driver IC's, I recommend for you L297 stepper motor controller with L298 dual h-bridge IC, you will need both of them to control your bipolar stepper motor, beside you will be able to control your motor speed and direction from either a PC port (e.g. parallel...
also you can toggle one of the output pins of the microcontroller on and off with little high frequency (20hz to 20khz i.e. audio frequency range) and connect it to piezo buzzer or speaker and you will notice some sounding coming out from it.
