I am looking for a talented freelancer to help me out with a project involving coding in Microchip Studio ATMega4808. The purpose of this project is to create firmware for a product design. The development environment for this project will be the Microchip Studio ATMega4808. Programming language of choice is C or C++. I'm expecting a freelancer with deep knowledge and experience with C programming language. If you think your skills might be a good match for this project, please get in touch.

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

We are in the end phase of developing several new tabletop products for the professional food industry. We want to create a great user experience for the interface. The first project would be to take over the software from one of our R&D partners - he makes the PCB prototypes and some of the mechanical solutions. Originally we just wanted to use DWIN but as he changed to a Raspberry screen, he programmed something in Python PyQT just as a method of controlling the product. It works, but it needs a talented UX developer to create a far more intuitive and more attractive interface. We would also like to add a language pack. Originally we just wanted to use DWIN but as he changed to a Raspberry screen, he programmed something in Python PyQT just as a method of controlling the produ...

PLEASE DO NOT BID IF YOU DO NOT KNOW BECKHOFF PLC AND TWINCAT C++. I need a project which has following features: 1. Get a byte[] package from UDP (if you have any PLC or access any real-time network card). 2. If you do not have any PLC or real time network card, you can use a simple ADS application by using C# which send sample data to PLC by using ADS library. 3. Read byte[] from PLC after that convert and save "protobuf" object. This part should written by using C++ in TwinCAT. You should you Visual Studio 2019. Important Note: No place holder bids! Thank you.

I'm looking for a freelancer to help me connect a Windows 11 PC to an unknown USB device and dump the firmware. It is a handheld device and a USB connection will be needed. The freelancer will need to be able to read and write the firmware from the device. All details should be carefully handled and no malicious data or code should be written to the device or sent over the network. The device should not be damaged or modified in any way. The output of the project will be the firmware for the device which must be isolated and kept secure with the capability to rewrite the firmware back again (or after modification). An ability to decompile/analyse the firmware once downloaded would generate another project of similar worth. At the moment I cannot find any USB drivers for this unit. ...

Therefore, experience in debugging and unit testing is preferred. I have the electronics ready to go to test the driver, etc.

Is there any posible way of measuring moisture in grain with arduino? What sensor to use? Are there any cheap sesor which can do that?

We have a bottle stickering line where bottles go over a Assembly line where the bottle goes through a product sticker (marked with a laser sensor). when the laser sensor has been triggered a new label will be pushed foward for the next bottle. This system is now broken. This works with a HMI touchscreen. The manufacturer does not respond back, so we need to make a new solution. I am thinking about a arduino/esp32 for the coding. We have relais, the wave a plc controller type: DVP-14SS2 (if even needed) We have a large steppenmotor and a label reading unit (that can be ignored if we use the sole steppenmotor). Can someone help us with this so that the sticker unit can work again. We have many more projects within our company, so it will be a longer cooperation.

We are an office with countless files. To make it easier to find these files in the future, each of them is to be fitted with an RFID sticker. About five rooms are to be equipped with a UHF reader on a Raspberry Pi. At one workstation, it should be possible to assign RFID stickers to files; this should be made possible via a web interface. It must also be possible to search for files via this web interface. This includes the name of the file, the file number and the RFID code. All UHF readers should then be addressed via a "Find file" button and search for the file (or the RFID sticker). The reader that receives the strongest signal should report that the file is in its vicinity. also we need to use a reader with a wide range, probably at lease 5 meters indoors

Hi, I need to program the LILYgo 7000G board to communicate via MQTT via LTE and wifi. It is also required to read the GPS position. Regarding the power part, it is necessary that the board goes into deep sleep consuming in general less than 50 ua/hour. To achieve that it should be possible to turn off the SIM7000G via software through the ESP32 and put the ESP32 into deep sleep. It would be necessary to see the rest of the electronic components and their power consumption.

However, instead of physically designing the board, the designer will create a digital representation of the PCB using specialized software. This digital file will contain all of the information necessary for the manufacturer to fabricate the physical board. During the design process, the designer must consider factors such as signal integrity, power distribution, thermal management, and manufacturability. These factors can have a significant impact on the performance and reliability of the final product. Once the digital PCB design is complete, the designer will generate manufacturing files that provide the necessary information for the manufacturer to produce the board. This includes information on the size and shape of the board, the location of components, and the routing of electric...
