Re: URGENT PLEASE HELP ME ARUDINO UNO/raspbery pi

There is a stickied post on this forum about how to ask questions the smart way. I suggest you read it and apply the concepts to your post.

In addition, we need to know when this was assigned and when it is due so that we may judge the actual urgency.

Re: Bad Registration Procedure

I should also point out that as the BOTS are programmed to correctly answer the anti-spambot questions, I see and uptick in attempted Spam posts from new users and I go an adjust the questions as a result. We had an uptick last week so now the question reads as follows: "Not including quotes, type t...

Re: RS422 vs 485

RS422 is spec'd to have a single always on transmitter driving up to 10 receivers on a single differential pair of wires where RS485 can have up to 32 bidirectional devices on a single differential pair of wires that are high impedance when not active on the bus. You can also operate both configurat...

Re: Bad Registration Procedure

You and hundreds of others managed to prove that you're not bots. I'd say it's doing its job just fine. Plus you can refresh it and end up with a different question.

Re: Help with chinese development board

LVP is something you don't need to worry about unless you have a specific use case for it.

About your PICkit-2 and IPE. This is another case of the answer being right in front of you if you read the literature. The PICkit-2 is not listed as a supported programmer in the IPE user manual.

Re: Help with chinese development board

I already told you how to do it. Open up the datasheet and map the pins like I said.

Re: Help with chinese development board

The board that you just bought is not an ICD2. It is nothing more than an adapter board designed to make programming multiples of the same part a little faster. The board itself doesn't actually do anything. It is up to you to route the signals to the correct pins for the device you're programming. ...

Re: Help with chinese development board

So I found the board on AliExpress and from the pictures they have, it looks like a 1:1 connection between the socket and the headers next to it. You will need to use the included jumper wires to bring power and the programming signals to the correct pins for the PIC you are using. The crystal oscil...

Re: Help with chinese development board

I can see that picture but unfortunately there still isn't enough information to say exactly what's going on. It looks like an adapter board for programming PICs that can be reconfigured depending on the size package you are using. For 40-pin PICs, some of the jumpers line up with important pins (MC...

Re: Help with chinese development board

Your image link is not working. Please fix that and try to provide as much information as you can about the board so we can help you.

Re: My first post is gone?

Yes there is. We moderate the first post of all new users in an effort to reduce spam on the forum. The upside is it's very effective at weeding out 99% of spammers. The downside is it can take a little bit of time before a moderator logs in and approves the posts. Now that your first post is approv...

All, This will be my last post here, and the admin can delete it so as to protect the sensitive, but I will have my say before this eventuality.

Re: PWM WITH PIC32MX460F512L

Another thing I noticed is your prescaler setting for Timer2 is actually 1:2, not 1:8 like you are expecting. If you were using Timer1, your TCKPS bits would be correct but for Timer2 TCKPS needs to be 0b011 for a 1:8 prescaler. Right now your PWM frequency would be 40KHz. When you say your PWM is n...
