******* bid only if you have knowledge, if you speak Spanish it will be a plus ******* We need to make a program in python for a raspberry pi that will be connected to a telescopic crane, this raspberry will have a display where the information indicated in the attached file () will be shown, basically it will show the speed changes and an arrow up or down when needed to display it. Currently we are able to connect with the j1939 and the raspberry pi and it throws us a series of characters that we do not understand: can0 385 [8] FF FF FF FF 28 FE FF FF can0 386 [8] FF FF FF FF FF FF FF FF can0 22C [8] 04 00 00 13 3C 02 00 00 can0 22D [8] C0 3C A8 61 A8 61 00 00 We don't know what each line means, so we need to make the python program that...

we want to develop a firmware on Raspberry pi Connected to single screen via hdmi On display there are 4 values displayed, And a countdown timer (3 minutes for each round). the values are being sent form another software already built. Communication is local, and is still not set but will choose the easiest way, most probably RF, meaning raspberry pi should parse serial messages.

Firstly you must have some Pi Picos otherwise please don't bid. If you’ve run some Pico test programs you’ve probably noticed the compiled programs are located in Flash memory and run through the XIP port, a form of cache. You’ve probably also noticed the extensive use of CMake in the build system, a large number of embedded sub-directories and a at each level. If you go to the outermost level you should see it pulling in the SDK and checking the version used. Then below this after the add-compile-options statement there should be a pico-set-binary-type instruction. If you change this to : pico-set-binary-type(PROGRAM_NAME, copy-to-ram) it should attempt to load the code from Flash into RAM and run from there. Now it gets complicated. The system I&rsq...

...and supplied links before automatically bidding, as I will disregard those entries. What I'm needing is to create a "Canary" using a Raspberry Pi, but every guide I follow is older and I have a lot of problems getting them to work with trivial Linux issues like incorrect version of Python or some missing libraries etc, I've had various success but it's not what I need... What I need is a finished image that I can write to an SD card and boot, the rest I can do. This guide is exactly what I'm looking for: I have a Raspberry Pi 4. What I want delivered is exactly in the tutorial but as a img file or iso that I can write to an SD card and boot. Finished project

PLEASE DO NOT MESSAGE ME BEFORE READING THE WORD FILE! Today, we have a system that runs on a Rasberry pi running a fixed ML code that was trained on a regular PC. The system monitors a signal from 4 or 8 seismic sensors (geophone). We want something identical but a little smarter. You can not use anything from the current software as we don't have the source code. We need someone who can bring us a complete package of algorithms and software. I would like to use as the training mechanism for the unit. We are looking for a relationship to continue working on this product and others for an extended period. The system should be at least the same as the system shown in the following video which is our current solution

...is the number one reason for elephant deaths. We are a team of around 10 people. I am volunteering since one year for this project (The hardware guy) and hope you can help us to bring this project to reality. As a non profit organization our budget is limited. Hope you can consider that as well :) At the end (Not part of your job for now): The trained model should run on a solar powered microcontroller (ESP32) as an elephant detector while it is constantly listening in the jungle with a connected microphone. These detectors will be able to spot elephants before they reach a farm or village and warn rangers in that area who can deal with that situation. This will prevent human-elephant-conflict. As far as i know only Tensorflow (With Tesnorflow Lite) or PyTorch (with TinyML)are...

I have a project I need doing. It involves the following: 1) A RPi, 2) Waveshare Barcode scanner () 3) A 16x2 LCD screen 4) A weight sensor module () 5) An RFiD module I need help with making everything work first with the most basic code, so we have the circuit correct. I already have LCD and barcode scanner working (barcode scanner has UART data receiving issue, but we can discuss it later). I will then give a logic on how everything will work together and you will help write the code for it for me. As this is time sensitive, please do not bid if you 'can' work with RPi but don't normally do. I really need someone who is an expert on this please and has worked with sensors with different communication protocols. Look forward to see some talented people for this project.

Refer to attachment Gate Circuit I have two raspberry PI's connected to each other through the UART. There is a gate circuit in between the two RPI's. The purpose of the gate circuit is to pull the GPIO pins LOW during periods of no data transmission (this is necessary to protect an amplifier not shown in the circuit diagram and not hooked up for the purposes of this project). The attached uart_tx_V3.c program pulls the GPIO pin (pin 24) HIGH which opens the gate in the gate circuit to allow the signal to pass to the receiver raspberry pi. Once the file has been sent, the uart_tx_V3.c program pulls the GPIO pin LOW to close the gate and not allow voltage to pass to the receiving raspberry pi. So far, everything seems to work except uart_rx_V...

I would like to use a Raspberry Pi to monitor liquid levels of multiple tanks. Utilising TOF sensors to monitor the liquid levels inside tanks. I would like to be able to display the levels of the tanks using Node-Red as the interface. The TOF sensors will be using HART to communicate with the Raspberry Pi. They will be daisy chained to each other. Using the Node-Red interface I will need to be able to select how big the liquid tank is (LxWxD) for different size tanks. With a maximum amount of 8 tanks to be monitored at a time.
