I need the firmware in Afro electronic speed controller to be customized. It should read a temperature&humidity sensor using I2C and run a brushless DC (BLDC) motor when the temperature & humidity is at a certain level. -The microcontroller should be in standby mode and check the sensor once a minute. -It should keep the last 10 temperature&humidity value in memory. If the average temperature<T1 and average humidity>H1 and battery voltage>V1, it should run the motor at RPM0 until battery voltage is <V0. -Since we will use supercapacitors to power the motor, voltage drops very quickly (half the voltage in 20sec), and the default firmware cannot keep up to it. The firmware should be optimized to compansate for it as the voltage drops. -Temperature sensor is SHT20. Here is the ESC: [login to view URL] This is the firmware: [login to view URL]

Hi, I am a final year electronics and computer engineering student, having worked with companies and as freelancer I acquired solid embedded systems experience, which allow me to deliver a result that is up to your expectations. Add to that, electronics background, can help me go from calculations (circuit wise) to simulation, and eventually to test it physically. I have also worked with ardupilot open source project before. Looking foward to working with you. We can talk more about this, agree on milestones and start to work. Regards, Nabil PS: check my reviews for an idea on my work ethics and the quality I deliver to my clients...

Hello, I would like to help with your project, bringing the required skills and experience. I believe to be expert in sensory, analog, RF, digital and power electronics design as well as embedded firmware for many microcontrollers. My usual design targets are formal correctness, manufacturabilty, lowest power and cost. Swiss citizen, having spent 8 years in Silicon Valley working first for Steve Wozniak (of Apple fame), I now reside in Italy and routinely solve multi-disciplinary challenges for clients in diverse industries. Please see my portfolio on Freelancer for recent accomplishments. These have been designed from scratch, electronics and firmware, using PSPICE, Protel/Altium, ARM Cortex, C8051, plus some exotics. Specifically, I am very familiar with the 8051F series from Silabs, using both assembly and "C". I have read the firmware on Github and am ready to start working on it once we have set the objectives. Likewise for the required hardware modifications. I have managed prototyping, interaction with ID, design reviews, end-user tests, certification, sourcing, documentation, production set-up and following at CMs both local and Asian. I would welcome your contact via PM or skype (alfredinok) for further discussion about this project. Thank you for the opportunity, Best Regards Alfredo Knecht

Hi, I already read the description, It is not clearly to me. maybe it is a hardware problem.I think we need ensure it is only the firmware's problem first. Please answer some questions: 1. Normal voltage of supercapacitors and the voltage when firmware stop? 2. There have 3 firmwares. Which firmware is used? Please contact me and discuss it. Personal description: I am expert in Circuit Design/PCB layout/Micro Controller program(PIC16/PIC32/MSP430/STM32/ARM7/ARM9 etc). I have more than 19 years experiences. I have developed a lot of products, some of these is used in China High-Speed rail system.
