...project that I am working on. What I want you to do is to check the files that I have already made using Nextion Editor and Arduino to talk to each other. I'd like you to check them, improve them in terms of looks, operation and help me with what's undone. Basic idea is we have a display and Arduino and we want them to talk to each other all time and make the changes on Arduino side, I also have an I2C based battery fuel gauge IC so I'd like you to help me to track it's SOC as well. If you are someone who has worked with Nextion Displays and can do this, kindly bid. I'd prefer it if you have the display at your end and can test the firmware on Arduino and test the HMI interface on the display parallely. Looking forward to hear from you. If possible, ...

Write a code for implement a digital vacuum sensor with RPi4 I2C. Already exists a ST32 dedicated code, so it could be converted into RPi4 format. Also I have my prior version that doesn't work, and can share for just correct it. Code shall use RPi4's SDA and SCL to get raw data. Attached is STM32 code for sensor. If you're not RPi4 I2C coding expert, please don't bid.

...with some I2C peripherals. Existing design includes PCF8574 IO expander which is based on I2C. Due to some technical reason It is required to replace PCF8574 with MCP23017. This is a part of the ongoing project. So for the moment my requirement is to do replacement of PCF8574 with MCP23017 (Will hire for next stages and other projects too only if work is appropriate). So for this replacement you have to do following... 1. Make required changes in existing schematic with all necessary components (such as strong pull-up/pull-down). 2. Do layout changes according to the updated schematic(as per step 1). Layout changes has to be done as minimum as possible, so that existing layout won't change much. Note: - Existing design has been done in PSPICE. - You must have knowle...

We need to design a battery-powered Raspberry Pi Zero realtime linux system that reads SMPTE timecode from audio in (when available) and display it on a 7-segment display - When there is no audio on the input, it generates timecode to audio out using Si5351A board or a DS3231 RTC There needs to be a startup loop that reads the audio input for signal, a 4-way switch for type of timecode, checks status of an open/closed circuit, and a push-button for user input. Once the push-button has not been triggered for two seconds and the circuit is open, then the timecode needs to start generating with the
