Need to create a sketch for Arduino IDE for Atmega328 and 2 12segment level indicator (stereo)

i want to make a GPS tracker PCB that will connect to my server using either TCP or MQTT. To achieve this, I'm considering using a main chip like the ESP8266, ESP32, or ATmega328. Additionally, I'll need two other chips or modules: one for GNSS/GPS and another for the SIM data connection. My goal is to achieve accuracy comparable to the Chinese GPS trackers available on AliExpress. I've looked into Quectel and Simcom, but there are numerous options available,i want some combination that offer performance and cost-effectiveness. you can suggest different chips if u think that they should be used. pcb will have some other basic sensors but thats easiest part --only bid if u have experience with gps and gprs/lte

Dear sir or madam. I would need help with programming. I already have an arduino program for my design (pcb with atmega328 ic) - it is about temperature regulation and also I use 1.3inch lcd display with ST7789 board for showing data. The problem is that if the screen freezes, it doesn’t refresh automatically and stays freezed (I need to unplug and plug again the power). I would probably need separate program for the screen, which would recognize when the screen freezes and then refresh it. Or do you maybe know any other solution? I hope that someone could help me. Have a nice day! Gašper Vidmar

Thinking of a small project to first test on an Arduino and then move to a atmega328 or other chip that will need to sense a small micro switch that will be Normally open. . If micro switch shows closed continuously for 120 seconds then chirp sounder until the switch is made to be open again OR a momentary switch has been tripped manually which will reset the timer. Will also need help with being able to move this over to the chip instead of the Arduino and this bid will need to cover the process of what all is needed to make that happen.

The system I des...system I designed is called "FPV Combat", imagine to play a dogfight simulation game but in real life with real RC (radio Controlled) models with "real" danger and a great amount of adrenaline! Take a look at this demo video: This is designed to simulate fight with infrared system on RC models such as planes, drones cars... I'm moving this project from ATmega328 to ESP32. It was originally designed to work with analog FPV system I need somebody that can help me migrating the project to the newer hw and implement MSP communication (canvas mode) for the different digital FPV systems available now in the market (DJI, Walksnail and HDzero). Additional features might be needed now or in the future but we can discuss about it later on.

Develop transmitter and receiver circuit and pcbs for 900MHz radio that takes extremely small amount of current to preserve battery life. Must be designed using discrete components, and not using SIM900 chips. The radio will communicate digital data bits at 1000 to 10000 bits per second, using half duplex. The radio should be able to communicate at a distance of 500 meters or more. The transmitter/Receiver circuit must be developed with USA Fcc requirement in mind. Must be able to pass Fcc tests. Must have in-depth understanding and experience with wireless and antenna technology we need to incorporate this rx/tx radio in our cpu boards. so you will need to build sample demo units, perform testing and give us feedback on the results, send the samples to usa for our own testin...

RS485 with atmega328 with IO ports needs to be designed.

I have tried to add as many details as required to understand the scope but I can be available if more information is required. The Background: I have a product that uses HM10 as a Bluetooth communication device. It sends received commands to atmega328 which in turn turns a light on or off (and does a few other things based on commands). Commands are very simple we have added Arodino code to run commands and achieve the desired functionality. Mobile apps: We have two native mobile applications. One for Android and another for iOS. Both worked fine until recently. The right hardware: We were using HM10 which was working fine with both iOS and Android. When you run the AT+VERSION command on this one, you get a response:"MLT-BT05-V4.45". This hardware has the attached me...

The library should support USART with for example 9600 baud on one pin (interrupt for receiving and sending with timer) I tried to adapt for supporting one-pin mode, but it doesn't work. Maybe because of changing of pins out and in mode. It is needed for a study.

I have an AVR C code running on a Atmega328/Arduino Uno, which is connected to a 433MHz receiver RFM01. The data reception is ok. All I need, is the code modified such that the Data Received can be viewed on the serial Monitor. The person to do this must know AVR C properly Thanks

This project uses the design and code from OpenEVSE, designer and manufacturer of open source electric vehicle charging equipment. The ATMega328 microcontroller is used in the project, and the code is maintained in C++. A modification of the source code is required to repurpose the I2C functionality of the controller to control a third-party off-the-shelf LED controller. More information about the controllers, code and progress to date is provided in the attached document. Version 5.0.1 of the firmware is currently being used. There has been some attempts at getting it to work, but no success yet. The progress to date is described in the attached document. More information can be found at or at the provided links in the document.

Need to edit a fritz diagram to swap the arduino with an atmega328 chip along with essential components (iE capacitor, 16mghz chip etc etc ) to make it replace the arduino.

I want to be able to program an ATmega 328 with a new firmware stored on an esp32, using only the esp32. The code for this already exists. I only need the programmig code from one project integrated in...another project, and tested. The ATmega flashing code for esp32 exists in this project: The project which I need flashing integrated into is this: Requirements: - You must be familiar with platformio. - You must have basic understanding of ATmega flashing/programming - You must own esp32 and ATmega328 boards, so you can perform testing. The project is complete when the esp32 code is able to successfully flash an ATmega connected to the esp32 board with a firmware stored on the esp32 SPIFFS.

In addition to this I will need to have a fritz diagram for arduino and also atmega328 chip provided showing pin out etc.

Hi David, I am a colleague of Kristof from Futech. You are building some C++ code for an atmega328 and an ESP32 controller. We did already some expensions to your first code. But it's now not working like we expect. Could you maybe implement still a watchdog timer at the program? Kind of regards, Jens

Create circuit with ATmega328 and Simulation using Proteus. -> Make the SCH fit to our requirements. -> 5W LEDs, Diodes ->Arduino software

We have 2 devices (already existing): A master device (pcb) with an ESP32 with a CANBus on it. A slave device (pcb) with a ATmega328 also with a canbus on it. The canbus is linked together and can talk to each other. We want to have a bootloader / sw that can be used for updating the atmega328. The firmware can temporary be stored on the ESP32 spiffs and send over canbus to the ATmega. If possible written in platformio, Arduino code for the atmega328 and arduino-esp32 for the esp32. If you already have experience with this, please contact me. An NDA needs to be signed when you need additional info, like electrical diagrams etc...

System: Arduino Mega 2560 / ATmega2560 with GSM SIM900 attached Needed: FOTA Suggestion, what I would need: - Bootloader capable for FOTA (maybe most important part) - Firmware to integrate into my main project for handling the firmware download from the website via the SIM900 (the hex-file output by Arduino IDE) (medium important) - Rewrite the firmware with the downloaded new version (important) - Reboot to start the new firmware version Main development for Arduino Mega 2560 (ATmega 2560) is done with the Arduino IDE, so the output HEX file from this site would be the file to download and update.
