I need stm32f103 configured has 4 analogue inputs, also conncted to i2c ac1115 , 2 PWM output with variable freq and duty cycle also controlling buck converter through pwm top set a voltage from 3 to 12 vdc to test the operation of a small dc motor where i can take the voltage and current reading to send it to the esp32 working as access point server , i need nice gui from chart gauges and sliders to control the 3rd pwm and set the voltage also be able to record fixed samples of reading can be preset and save the readings on a file on the spiff storage of the esp32 also i need to be able to retrieve the saved file/data and show it on the web server to compare it with current testing dc motor, i need all the load on the stm32 so u can free the esp32 just to work as web server, similar project as u can see in this link. time is not an issue but this code must be done with arduino official cores as far the stm32f103 or esp32 [login to view URL]

Hello, thank you for your job posting. I read your description about your project I am a senior electrical engineer. I have plenty of experience in firmware development and micro-controller developments. I can write the firmware based on Arduino, Raspberry Pi, Pic, Atmega, FPGA, ARM, DSP, PLC and so on. And I can design the circuit by the Altium, Eagle, KiCAD, Allegro & OrCAD, PADs. I provide the services - Gerber files, Netlist generation, BOM generation and 3D Models of PCAD and ECAD. I am also good at AutoCAD, Solidworks. And I can simulate all circuits with Proteus, LT-spice, Matlab, Simulink, Multisim, and Labview as well. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I will also give you a detailed explanation of the process. Looking forward to hearing from you soon Thanks
