    I am in need of someone to copy data from an EEPROM. The data I need to copy is configuration data, firmware data, user data such as BIOS, NVRAM and firmware, etc. I do not have the necessary equipment to complete this project, so somebody with the tools required for the job is essential. Additionally, after the EEPROM data has been copied, I will need it to be physically delivered to me via a storage device. If you think you have the tools and knowledge to complete this task, please feel free to submit a bid for the project. Thanks!

Due to the current global chip shortage, we need an alternative that can work as a replacement. We want a drop-in replacement so no changes will be needed to the circuits that interface with the chip. If a few basic additional support components are needed to achieve this, that's OK, but we don't want to add a huge amount of complication and cost to the circuit.

    Javed! You did an excellent work setting up WiFiManager and AsyncHTTRrequest for my ESP32 project. The project is now almost finished and I have added a lot of new code. But there are two small features I would like your help with: * A user should be able to edit URL used for the HTTP request through WifiManager. * The code should save the last result received from the HTTP request in the EEPROM, in case WiFi goes down.

    ...electronic device is exclusively done via Near Field Communication (NFC). The electronic device is equipped with an ST25DV64K dynamic NFC Tag (Type 5 Tag). The commands to operate the electronic device are written in NFC Data Exchange Format (NDEF), in particular ‘NDEF text records’. A different method/protocol could be agreed as well, most important is that the App is able to write data to the EEPROM of the NFC Tag. The main function of the App is to display measurement data. The measurement data is provided by the electronic device via NFC. This data needs to be presented on the mobile (phone) in a graph. The X and Y axis of the plot are given in the same unit and the plot needs to be true to scale. Landscape format and a zooming function might become essential. Th...
