| Feb 25, 2017 at 7:16 | comment | added | h_uat | @AngeloQ: which voltage to frequency converter would you have in mind? I had a look at the other comments and i think it is not working with that. (see my edits in the post) | |

Explain why Arduinos PWM is not sufficient and register method is not working

Include that bit banging is not feasible

| Feb 24, 2017 at 20:59 | comment | added | h_uat | I do not need to count steps. I have a position read out system for that. I will have a look at the PWM hardware stuff. I had a look at that one already: arduino.cc/en/Tutorial/SecretsOfArduinoPWM but it seemed to me that the steps are quiet big between the discrete frequency levels, but perhaps i got it wrong. The problem with the toggling is somehow that it will block the microcontrollers processor (please correct me if I am wrong) and I could not continue reading out my sensors at the same time. | |

| Feb 24, 2017 at 17:28 | comment | added | Chris Stratton | The premise of your question is based on misunderstanding, you can toggle digital pins a lot faster than 1 KHz. | |
| Feb 24, 2017 at 17:01 | comment | added | Wouter van Ooijen | Dive into the Mega 2560 PWM hardware. I am sure it can be run at some speed suitable to you. But you might need to do it yourself instead of relying on the Arduino libraries. | |
| Feb 24, 2017 at 16:17 | comment | added | AngeloQ | Do you need to count steps? Do you just use it for speed control or do you have an encoder? If you only need to control speed, maybe a voltage to frequency converter would do the trick. E.g. ti.com/product/LM331 | |
