Type picInfo to find out how to install the UxV blocks. Hi Guilherme, Please give a try with the v3. We will try adding it shortly.

Please, could you suggest a solution for this problem? When the Master is compiled, the slave will also get compiled and the. Many thanks. Merci d'avance, Cordialement. You might copy examples in the current working folder typing picInfo at matlab prompt then click on links provided. Some examples deal with I2C. Could someone be kind enough to post an example of using the I2C block; please, why is there no help file for these block as provided for others?

How does one obtain this embedded coder or is it needed.

We want to publish your embedded source code for the benefit on the PIC community. Reasonably well known code, makes handling of data easier. Data types for Hi-Tech C. Example project illustrating delay and timeout routines.

Unlike the routines available from the Hi-Tech C site, these are written in in-line assembler and thus give precise timing. Delay routines v7. Note: these routines could cause problems if Hi-Tech C banks the assembly variables in the incorrect bank; the problem would only surface on a large project with high RAM usage. Delay routines v2.

Thanks in advance. Ariel Rocholl Did you try the sample code from the Microchip website? IIRC there is a sample application for each peripheral in the "code examples" in the part reference page. Hi Ariel. Do you refer to this? Patrick Moody. Hi Patrick. I have all family reference manuals also the one you linked but none of them has any sample code.

I know actually most of bits are zero. Vicent, In my code, I first assign QE1 pin select e. A quick inspection of my code rather large I don't think I am missing anything. I would start looking into POS1CNTL in a simple loop, and consider more complex approach like interrupt service only after the simple loop works for you. I didn't need any capacitor to handle bouncing in my case but I wouldn't guarantee this is always the case: I first started with 10nF capacitors and later found the internal QEI handled bouncing well by itself with no capacitors, so removed them in final prototype.

What are them for exactly? I left them at 0 value. I hope this is IT and we have catch the bug. I tell you back in two hours. In reply to this post by arocholl. It is too easy to make a mistake doing it that way, and no one else can understand what you are doing, and they are not going to look at the data sheet to double check it.

Alan, My compiler does not support this part directly, hence I have to do it manually. What compiler are you using? The project this code comes from is using CCS compiler. Working now!!! Solved PWM question. If you left this register to zero, the PWMxL just does not works or works with a zero duty cycle, wich in fact is the same.

This is the first time I see this in a micro. Can you show me your piece of code about QEI?GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

PLL settings not working. UART communication is not working. So, I guess there might be error in my code. Learn more. Asked 4 years, 2 months ago. Active 4 years, 2 months ago. Viewed 1k times. I am facing two issues while debugging.

Got the Issues. This is a moment where having a scope pays off. I meant you assign 19, but have rpi25 in the comments. MarcovandeVoort, Thanks alot. You have really saved me. Its working now. Beside this PLLSettings also have incorrect values. So, I will post the complete code again.

Tin Duc Vo Contributor Posts: Hey, everyone I have another question. It seems that everything on dsPIC33 is a bit hard to find information on. Right now, I'm trying to use the QEI module, but I do not understand how to even use the peripheral library. Additionally, I do know how one would determine the direction of either the position or velocity.

The functions are: 3. I do not know what the capture read is supposed to do 3. I do not know if the only way to infer position sign is to use the index counter and whether is overflowed. In general, I just do not understand.

I've looked everywhere I could. I also signed up for the microchip forums, but I haven't been admitted. If someone could point me in the right way, that would be lovely. Thank you. For example, to obtain direction it was done just subtracting two consecutive readings, if greater or smaller than zero, meant clockwise or opposite direction.

To obtain the speed, I had to make the division of the previous result by a constant value, proportional to the sample interval. Thanks Andre. I know it could be done that way, but it seems like there is hardware support for velocity and the other stuff too. For some reason, the velocity is returned as an unsigned value.
