What I am looking for is a skeleton of a firmware for a Nordic NRF52 device. The firmware should: On boot, sets up the pins and peripherals. Has functions to read/write I2C data to/from the IR Thermometer, Heart Rate & Pulse, Accelerometer, Gyro, Compass, ECG Clock, and Battery Charger. Has functions to read/write 4-wire SPI to/from the ECG sensor Has functions to read I2S data from MEMS microphone Has functions to read ADC value for Glucose Monitor Has functions to set a PWM output value for Red, Green, and Blue LEDs. Only used for human indication. 8bit resolution would be fine on the PWM as long as the strobe is kept higher than 30Hz. Want to be able to adjust the clock a bit it is on in case there is an alias with the IR thermometer or heart rate/pulse sensor SD Card is not used ADC will not actually be used but it would be useful to have code in there as an example Go to sleep when idle and shut down the non-used power supplies. Wake them back up coming out of sleep I like the idea of using your round-robin style scheduler for these tasks That would be the extent of the hardware to/from the module on the PCB itself. Then for the actual BLE magic, looking for code that can Report back IR Temp in degrees C as the sensor reports it Report back the heart rate and pulse as the sensor reports it Report back 9 axis worth of data from the accel/gyro/compass as it reports it Report back the ECG data as the sensor reports it Ideally be able to stream the audio data live over the BLE connection in a way that the phone could play it on its audio output channel (speaker / headphone) Report back an ADC value for the glucose monitor even though it won't be used Report back battery voltage as read from the TI battery controller Has an interface to send data chunks from the app to the BLE module such that Configuration registers in any of the sensors can be changed. Something simple like a few bytes of data being passed back and forth is fine. We can make up a proprietary encoding that allows the one stream to talk to all sensors' config. One configuration register would be some ram on the ble module itself to say what state it is in or what the user is expecting the hardware to do (like wake up and read the ECG or become a stethoscope)

Hello, How are you? I am very interested in your project since I have practical experience in use of nRF52832 Nordic firmware programming. This year I have finished Nordic project, which built local BLE networks using BMD350 modules. Also, I have experience in car diagnostic system design where nRF52840 was key component. I have fully checked your project description and quoted price and estimated time with my experience. Looking forward to having opportunity to discuss on your project in detail via chat or call. Thank you. Alexander

I am an Electrical Engineer having specialization in Electronics Control and Power, teaching at well known University in Pakistan. I have done my BS degree in Electrical Engineering with specialization in Power. Also i hire many persons in my Company for freelancing. They know many skills like Graphic designer, Logo Designer, Video Editing and Data entry. I have taught the followings courses, and also done many projects related to these subjects as well as related to consumer electronics products. 1. Control System Design & Modelling (Continuous, Discrete, Linear, Non-Linear, Optimal, Fuzzy Logic + Matlab & Simulink) 2. Digital System/Logic Design (Verilog, VHDL, Logisim) 3. Digital Signal Processing (MATLAB) 4. Micro-controllers (8051, Arduino, PIC) 5. Power Electronics (PSIM, MATLAB, PSpice) 6. Control of Electric Machine Drives 7. Circuit Analysis and Designe etc 8. PCB Design (Proteous + Ultiboard + Altium Designer) I assure you, if you assign your project to me, you surely gonna work with me in future. Note: I also provide the services in Mechanical Engineering and Computer Science related projects.
