Hi ! I'm building a DIY music instrument based on the Suzuki Omnichord. I already took care of the hardware but I'm not able to built a satisfying in-built synth sound in the Arduino IDE for the Teensy 4.0 board. What I need is pretty straightforward : - A polyphonic (16 voices minimum) synthesizer with filter and LFO - With ADSR enveloppe control (will be controllable via hardware potentiometer) - With Chorus and Reverb effects (will be controllable via hardware potentiometer) - Controllable via USBMIDI library - The goal is to achieve the closest sound possible as the one of the omnichord (see the .wav example file) - Ideally, something that can be tweaked enough to allow up to 6 rather different presets controlled by a stepped POT. Thank you in advance for your help !

Hello, I am looking for some...function that will transform a 300x400 pixel grayscale image png to an array of hexadecimal values in a format suitable for display on a Waveshare e-ink display. Looking at the page of the brand of the screen (Waveshare), after transforming each pixel into its hexadecimal format, it then applies an MSB compression. Going from 120,000 hex values (300x400) to 7500. I already have the function in arduino. I just need the function in python that transforms the image. I am attaching a .cpp file containing the list, to use as an example. It is the one that comes by default in the demo screen. If you wish, I can also send it in a txt file for your ease of opening the file.

As the project title suggests, I require the upgrade of an existing arduino code. The desired updates to the code require modification rather than complete replacement. No additional materials are needed, however the updates will need to be tested extensively before being finalized. The desired outcome is to have the code updated and properly assembled with the right materials resulting in a good result. The necessary full testing must be done to guarantee the desired result. I think it's necessary to check the algorithm for the result of remaining life. that's it HERE the base project to understand : i re made this project with somes upgrades.

hi I wrote a programming code to control three pressure sensors with a Arduino Mega. I have 5 modi with different units like (mmhg,mbar ..) and 5 switches. I want to turn on each modi when the depending switch is flipped. So I put them in a aray. The idea being that the code in this example reads the voltage on a switch pin and determines whether that voltage is above or below a threshold. > If the voltage is above the threshold, the pin is turned on (1) and if the voltage is below the threshold, the pin is turned off (0). > The code will check the voltage on each pin of the switch and if it is greater than 3.0 volts, then that pin will be set to 1 (on) state. > If the voltage is less than 3.0 volts, then that pin will be set to 0 (off) state. At least that's the ...

I researched algorithms for canceling motion artifacts for ppg signals, and I found that most of them use algorithm that are beyond my scope of understanding. Therefore, I want you to write an Arduino code that includes an algorithm to accurately detect heart rate, SpO2, and temperature using the MAX30102 sensor while walking or doing other physical activities. Also, the MAX30102 should be placed on the index finger, not other parts of the body. Thank you.

I would like you to setup the lvgl and port the initial sqare line design to the arduino framework. The hardvare is esp8266 and st7735 128x160 lcd without any touch input. Also it would be nice that the code would have as much coments as possible so I understand what line is doing what. The idea is to make an scooter/ebike controler that will interface with vesc based controllers. The actual interfacing and logic (backend, if it can be called like that :D) I can write by myself. But the lvgl part is quite daunting for me at the moment. So far I have made preliminary sqare line studio designof the gui. The gui will not have any buttons or methods of input. It will only display info from the esc and other components. The gauges and other indicators should have float inputs.
