It is correct that it isn't many lines of code but for a beginner python programmer (python mainly being a higher level language) it is a little confusing understanding viper code and masking and reset(&= ~) or set(|=) It is true that working out just how the python implementation should look and wo...

I think it should be considered adding the the feature to the machine class the ability to be able to set multiple pins at once that all are in the 1 register as it is not uncommon that people will want to write code for parallel pin operations.

No I haven't :( My business has been super busy lately and I have been working more than 12hrs a day and 7 days a week for last couple of months. On my short list is to build a robot for a comp coming up next year. What is on my list to do is to write a pure python implementation using viper mode of...

You can build under Eclipse if you install MSYS 2 and the toolchain. Then import a makefile project instead of building an Eclipse project. I originally started building STM32 projects like this but found it easier to use "system workbench". System workbench is basically a modified version of eclip...

First of all this can be all done much easier using addressable LEDs like Neopixels (shift register is pretty old school) If you did want to implement it I think you will need to build a little circuitry. The shift register would operate a transitor that turned on the power supply to each LED then a...

I see this ;libiary has featured on Hackster.io https://www.hackster.io/news/zoltan-vor ... 9oOo5q-u1I

I haven't used it but the Arundio boys are liking it as a replacement for the blue pill due to the FPU of the F4 over the F1

I do believe u can buy it for about $3US

I have found timing problems before. Although sellers advertise them as WS2812 quite often they are clones and the clones quite often require a slightly different timing. Some types that I have encountered ws2813, ws2812, ws2812B, WS2811, sk6812, SK6822, cs2803. You have to read the data sheets to f...

AS Roberthh has said you can use interrupts then count with software and you will achieve a good results. The ESP32 does have a hardware peripheral designed to do exactly this which doesn't use any CPU load. see https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/pcnt.htm...

Make sure you put a 100nf caps on the rst pin or you will find it will have unstable operation at minimum and may even reset when you use wifi due to dipping on that pin. I would also recommend a 10uf and 1uf cap on the VCC pins. I have not included these before and found the ESP32 worked but was un...
