Re: hall effect tachometer

That would work. Special attention is required to clamp out the high voltage that is generated at high speed.

Re: I2C on bluepill - trouble

dRob, I don't have an advice what could be the explanation for the symptoms you are seeing. My generic advice is, slow down. It was just a few hours when you asked about the I2C pins. Now you found them and are immediately asking next help. We are very helpful in this forum, but we would like to see...

Re: hall effect tachometer

If you are using the normal hall sensor activated with a magnet, there is no debouncing. Here are some general comments: 1. Busy reading of an input is not a good idea. At that time, your application cannot react to anything else - unless you are using a genuine RTOS 2. Resetting counters/timers can...

Re: Fast PWM on Nucleo-F030R8 with Arduino IDE

Here is a list of solutions that you can use for the speed (and positio...

Related to Aliexpress, I have been using Taobao as an alternative for items not available in Aliexpress - or lower prices. In several cases there, the delivery from China has been quite quick, only a few days. After that, the packets have been in Germany for several weeks. Once leaving Germany, they...

Re: Aliexpress delivery times

For me, last year average was around 20 days. This year the average has been around 15 days. The main explanation could be that I have preferred the few dollar deliveries promising quick deliveries. In the past, the free deliveries could have taken over 6 weeks. The delivery reliability has been aro...
