There are 5 posts supporting Nigel and only one against him; clear win for Nigel.
When Nigel said that I was talking rubbish he was right, my intention was to talk rubbish to him because I didn't feel the need to supply him with explanation. I was fitting myself in with the rest answering the OP...
Your DSN file doesn't open probably because my version is old, I can't update it soon.
If your circuit as you describe it then it has to work. The only thing I can suggest is that if you powered your circuit with 200 ohm first then the sense voltage exceeded its max rating. If you are very...
Thank you cowboybob for the kind words and the support. I detected 'angry Nigel' right from the start and luckily it didn't take long to get used to him.
The 200 ohm is the error, and yes, you must use the sense output. If you don't need to sense the current through the motor you must connect sense (pin 1) to ground. If you want to sense the current use 0.1 ohm resistor. The 200 ohm you use is in series to the motor and limits the current to 25mA...
There was a discussion about making coil from iron wire, this question relates and has the same answer.
The theory is that conductor creates a magnetic field around it that relates to current. That magnetic field in turn generates voltage on the conductor. At the middle of the conductor the...
Same as you I often refer to microcontroller as "he". I'm sure microcontrollers are based on the brain of a man and this is why they can do only one thing at a time.
I bought about 10 items from Banggood.
About half of their reviews are written by one person, you can tell by the style of the English used. They don't have even 1 bad review, this must be a Chinese humour.
Banggood business is based on fraud; why a customer has to be an actor and video producer...
Since Banggood are cheap and you need one I think you should try it.
It is possible that they have special hearing test for people like you who are difficult to convince. Those tests are designed to fail even people with good hearing. You should take their tests only as an opinion and at the...
Interrupt can do the job but you don't need one, a simple loop can do it. Your main function repeats all the functions of setting up the pic and after you increase the counter to next PWM you go back to start and setup the pic again.
Put all the functions that setup the pic at the start of...
I'm with the minority who accept your claim that manufacturers cheat. I also test them when I can, I think we shell all do.
I also agree with the evaluation and the tests you did. I'm not so sure about your final conclusion and solution though :-)
The only points that I like to make have...
