I have a temperature sensor that reports temp_object & temp_ambient over I2C. I have a 128x64 OLED display that runs over I2C. I have an Arduino Nano with Datalogger shield that contains a real-time-clock & micro-SD card. I want the temperatures logged in the micro-SD card and time stamped. I also want the display to update the temp_object in real-time so I can visually confirm the device is recording and get a sense of temp increase/decrease (not sure how long my batteries will last). I have patched together various codes and confirmed individually that: 1) code to report temperatures is correct (ta & to) 2) code to print time-stamp is correct (#include RTClib.h) 3) code to create & refresh display is correct (#OLED_SSD1306_Chart.h) 4) code to write data to micro-SD card is correct (SDFat.h) I am having trouble bringing it all together in a single file. The sketch uses 95% of program storage space on my Nano. I have already set USE_LONG_FILE_NAMES to zero in my SDFatConfig.h library to reduce library size. I may need to use Fat16.h if SDFat.h memory space is causing stability problems. Looking for someone who can study, modify, and comment lines 1-40 & lines 890-1030 so that I can get it running and understand how to modify it in the future. I understand that you will not have the specific hardware to debug on your end. I will need to execute the code on my side, so I hope that loop works for you.

I have great experience in creation, modification and remote debug of the code for Arduino I may need a copy of all of your libraries. In the most cases, I don't need to use remote debug for this job, it can be done at my side. We may need to use TeamViewer only at the final stage, but that's not mandatory. I have made more than 200 Arduino-based projects on different freelance stocks. I work with Arduino since 2010 and have more than 25 years of experience in programming and electronics.

I can compile your Arduino program, and noticed that (like you mentioned) the program memory usage for an Arduino Nano is almost 100%. The code is well written. Did you write some of the MLX90632 routines yourself? I think - rather than opening and closing the log-file on every single iteration of the loop - it would make sense to leave it open in the setup() function. Then just ensure to call flush() on the filehandle after every write (as you are already doing) - to avoid data-loss. Aside from the memory usage problem, what other problems are you facing? Although I do not have MLX90632 sensors to test, the logging functionality looks like it should work (although you are missing a new-line when logging the temperature). Regarding the memory usage ... It seems that switching to the u8g2 library instead of the SSD1306 chart library might save program memory - although it could use more dynamic memory. (You also would not have the convenient graph/chart functions if you use u8g2.) One of the other bidders suggested using an ESP8266 or ESP32 instead of an Arduino Nano. I think this is worth considering also. (It could be an ongoing battle with memory usage on the Nano.) I would also be able to assist you if you chose that route. I am based in Ireland. Please note the timezone difference.

Hi there, I am ANSAR an electronics engineer and enthusiast, expert in embedded system design and programming. I have done many projects on arduino including interfacing with sensors, communication with various ports UART, SPI, I2C etc, also have worked on various wireless modules including RF, nRF24, wifi, bluetooth and SIM module SIm800, SIm900, SIM7600 4G module etc. I have gone through your requirements and think I am able to serve you, You can further reduce the size of program by storing constants in progra flash memory, moreover prefer to use local variables instead of global variables, use functions for the repeated execution. I can optimize the code and will make it as small as I can. WIll complete your project with great perfection and complete testing prior to delivery with full commented code. Will also provide any online assistance with all the circuit diagram and schematics. Looking forward to get in touch.
