Re: A library for reading rotary encoders (ESP-8266 and Pyboard/stmhal)

This leads to other questions about the RTOS and WiFi. Obviously I have chosen the ESP chipsets family because of its WiFi ability. Is there a way to adjust priority level of the wifi and how much resources it consumes. Does running its own access point consume more resources than being connected to...

Re: pin.irq priority

Thanks for both of your response. At least now I understand the priority feature and this will be handy. I have ordered a ESP32 but am still waiting for it to arrive. I am hoping that it is not only faster but dual coare so this might fix the problem. I am hoping to be able to put my interrupts on 1...

pin.irq priority

I am currently playing with high resolution motor encoders which means I need fast high priority reading of the encoders pins. I am currently just using a pin.irq(trigger=(Pin.IRQ_FALLING | Pin.IRQ_RISING),) and this works fine while the ticks are below about 900hz but once they get above that then ...

Re: A library for reading rotary encoders (ESP-8266 and Pyboard/stmhal)

I am using a quadrature motor encoder, it is a magnetic encoder with 11 pairs of poles poles attached to a motor and the motor has a 31:1 gear box so I get a very resolution per rotation. I have tried both writing my own routines and using the great 1 written by spotlightkid. I have found them to wo...

micropython framework

First of all thanks to everyone that is donating their time to make micropython a reality. Ok I am new to micropython coming from Raspberry pi. One of the reasons for my learning about micropython (mainly for the ESP chips) is to get around the real time problems that RPi has due to the operating sy...

picoweb

Thanks for the add to the forum :) I know this issue has already come up that upip can't install picoweb on the ESP8266 enough there is enough flash to fit it the package there isn't enough memory for upip to do the install routine. I believe the work around is to compile the package into firmware b...
