THE HAIRLESS MIDI TO SERIAL BRIDGE This is an installation guide for the Hairless MIDI to Serial Bridge on Ubuntu. Install the dependencies. The Hairless program is a 32-bit executable, so on most modern 64-bit Linux distributions, you'll have to explicitly install some 32-bit libraries to be able to run it: EXPONENTIAL MOVING AVERAGE Exponential Moving Average. The Exponential Moving Average filter (EMA) is a very useful filter for smoothing all kinds of data, and it can be implemented very easily and efficiently. On top of that, it is a great way to enrich your understanding of digital filters in

general.

FLASHING THE ESP8266 WITH AN ARDUINO UNO Flashing the ESP8266 with an Arduino UNO. The best way to flash an ESP8266 is by using an ESP8266 development board (e.g. Wemos D1 mini or NodeMCU). Alternatively, you could use a bare-bones AI-Thinker module, and program it using a USB-to-Serial converter. If you don't have such a converter, it is possible to use the internal

Most of the microcontroller functionality of the ESP uses exactly the same syntax as a normal Arduino, making it really easy to get started. A BEGINNER'S GUIDE TO THE ESP8266 Go to the Arduino IDE again, and under Tools > Flash Size, select an option with the right flash size for your board, and a SPIFFS size that is larger than the size of your data folder. Then upload the sketch. When that's finished, make sure that the Serial Monitor is closed, then open the Tools menu, and click ESP8266 sketch data

PIETER'S PAGES

A fast and easy to use digital filter library for Arduino-compatible boards. It supports real-time filtering using discrete-time finite and infinite impulse response filters, and has functions to design Butterworth and notch filters. Different implementations are available, and high-order filters can be factorized into second order

sections for

C++ IMPLEMENTATION

C++ Implementation. We can now implement Equation 2 directly, and we'll use a rounding division instead of truncating the quotient. Note that this rounding operation is valid for unsigned integer types only. The previous inputs x are kept in a circular buffer. THE HAIRLESS MIDI TO SERIAL BRIDGE This is an installation guide for the Hairless MIDI to Serial Bridge on Ubuntu. Install the dependencies. The Hairless program is a 32-bit executable, so on most modern 64-bit Linux distributions, you'll have to explicitly install some 32-bit libraries to be able to run it: A BEGINNER'S GUIDE TO THE ESP8266 The IP address consists of 4 numbers, for example 192.168.1.5 is a valid IPv4 address. It actually consists of two parts: the first part is 192.168.1, this is the address of the local network. The last digit, 5 in this case, is specific to the device. By using IP addresses, we can find the ESP8266 on the network, and send messages

to it.

SETTING UP THE WIFI CONNECTION On your computer, install screen : sudo apt install screen. Then open the serial port using screen: screen /dev/ttyUSB0 115200. Replace /dev/ttyUSB0 with the actual tty the Pi is connected to. 115200 is the baud rate. Now that you have access to the Pi, you can start configuring the network. EXPONENTIAL MOVING AVERAGE Exponential Moving Average. The Exponential Moving Average filter (EMA) is a very useful filter for smoothing all kinds of data, and it can be implemented very easily and efficiently.
