Hello - I have been using the DFPlayer Mini module for years with great results. It is my go-to MP3 player. I have been given a new project where I need to be able to determine the number of MP3...

Brian - If you wanted to set LED #213 to red and all the rest to black (off), you would send a single command for a red led and then 212 commands for black and then send the latch comand. Is that...

Can you use that with PICBasic Pro?

Hello Everyone - Thanks for your posts. I am sorry that I droped out of this, but I am now in Mexico dealing with a family illness. In my spare time, I have scoured all the forums, blogs, posts...

Hello - Has anyone done anything with the LDP8806 RGB light strip? I have seen examples of people using the Arduino, but nothing in PBP. Would love to get something like this up and running for...

Darrel - Unfortunately, you just about know as much as I do. The person that wants me to do this is being pretty secretive. Here is a little more... I am assuming it is a motorized vehicle and the...

Just did a quick look at Sparkfun for accelerometers and found that they have a bunch that look like they could easily be used with PICS. They have a nice comparison here:
...

Darrel - Thanks for that very nice example! I completely understand what you are trying to get across now. One last question... will this be sensitive enough to tell if you slooowwwwllllly coast to...

Bruce - So, if an accelerometer is attached to a moving object and the object is moving at a constant speed, I will get some feedback that the object is moving? Even over a smooth surface?
...

Thanks Guys - Price is a factor (of course), so GPS will probably be out. Rsocor01, you have a point about the "jarring" effect of walking and the use of an accelerometer to detect that, but now we...

Darrel - Thanks for your response, but don't accelerometers just detect changes in speed? I would think that once speed was constant, there would be no signal until the speed changed again (sped up...

Hello - I have an application where I wish to detect my movement over ground (asphalt, dirt, grass, snow, etc.). I need non-contact measurement from about 3 feet off the ground. I am not concerned...

Hello All! Thanks so much for your replies! For some reason, I did not get any notifications of your responses like I used to get - I guess there's a new flag that I need to set on my account to...

Hello - Is anyone aware of a digital pot that is capable of handling a high current (20 mA)? I need to control the output of an LED but I can't use PWM. The LED is being monitored by a spectrometer...

Well, I figured out my problem. I had the wrong value for SetPlay. Once I found that, everything worked fine. Here is the updated code:


@ DEVICE HS_OSC ; Hi Speed Osc
@ DEVICE...

Hello - I have started playing with an ISD4002 and have a working circuit and program. If I just want to record a message using the REC command and then play it back using the PLAY command,...

Ya know - I really cringe when I have to finally break down and have to ask for help from you guys on the forum because when you figure out what my problem is, it is usually me doing something stupid...

Bruce - When it gets the valid command to play the sound clip, it plays. There is a status LED on the player that flashes when it gets the comand. It does not do that. I can take this player off...

Bruce - Thanks for your elegant explanation - I now perfectly understand the difference between ST and TTL level inputs. Nicely stated!

And what you said about ST pins being used as xmit pins...

Bruce - Thanks for your reply. What you said is starting to make sense... For a ST pin to recognize input, it has to reach ~4V. For a TTL pin to recognize input, it has to only reach ~2V. Is that...

The saga continues...
For a new design, I am using a PIC16F877A and trying to communicate serially with this same MP3 player - essentially running the same code that I had on the 628. You will...

Dave - Yes, I could have done that, but I have a bunch of these and size was not a problem. I will certainly consider that for the future... Thanks!

That was IT!!!! You guys are so awesome!!! Thanks! It works perfectly now... Funny how that one was the only one where it mattered that I had it backwards. I had the right addresses (except one)...

Hello - I have a strange problem when trying to access an EEPROM at a certain address. I have a string of five 24LC256 EEPROMs all sharing the same clock and data line. On the first 4, I am storing...

Skimask - Then that is exactly what I need! Thanks so much!
