Hi,
I've been busy on other tasks therefore haven't obtained a oscilloscope
trace yet, but one of my peers have performed some profiling on a different
micro and non-secure core, with the mxrt1064-evk:nsh configuration +
tickless and 100us tick rate:
nsh> dd if=/dev/zero of=/dev/null bs=4096 coun
Hello,
I am a developer using NuttX and would like to be added to the mailing list
for NuttX development.
Thanks!

Hello world :-)
I am working on ESP32 (no FPU) and using Quadrature Encoder for motor
control and range positioning. Current qencoder implementation stores
counted values on int32_t so the maximum and minimum value is only
around +/- 32k. I need far bigger numbers to be counted and available
for r

Email aggressively remove the sender from the reply list when sent to a
list so they likely did not get this email. I was doing the same thing a
couple weeks ago Added them to this one.
Sharwin Patil hopefully you get this response from Nathan.

The index signal (Z index) should be used to reset the encoder position.
You can miss an encoder step for various reasons, and without periodically
checking the absolute position (index pin), you will accumulate errors.
Then, if you set the maximum count of an encoder timer to encoder
resolution, t
11 matches
