This Project is for voice recording . Have a schematics design and need source in "C" (Prefer MikroC ) language for feature upgrades. Project diagram : Need to use ADC with starting interrupt for a specific time and record data and time to SPI Flash Memory. When finished recording CPU and memory will going to low energy mode and wait for interrupt . in boot section need to check serial connection for PC. when connected to PC need to wait command from PC (Data transfer , clear memory, and same other commands) Purpose in this project is to use very low energy

Hi, I am very much interested in your project as I believe I have the expertise, knowledge, skills and tools to do your project. I am embedded software developer with more than 8 years of experience of professional embedded software development. Please take a look onto my profile to know more about me. I have quite a lot experience of ARM processors specifically Cortex M0/M3/M4. I have written and used low level, middleware as well as higher level code. I have J-link debuggers, couple of STM32 development boards (STM32F107, STM32F446, STM32F429, STM32F405 and STM32F407). I have quite a lot experience with IAR, ARM GCC and Keil compilers. My recent projects that might tell you my knowledge, 1. STM32F407 Discovery based CAN Data logger to log CAN data into SD Card (SDIO mode) and emulate USB MSC Class to read/write SD Card data and Custom HID Class implementation to send/receive interrupt data. 2. STM32F405 based FATFs to read/write SD Card (both SDIO and SPI) 3. STM32F407 discovery board to read via I2C BNO055 9 DOF IMU senor and save readings as CVS file using ChanFs (FATFs) in SD card in SDIO mode. I would recommend to use STM32 processor as it is supported by ARM GNU compiler. Also STM has good Audio codec library for it. I hope that I will be able to write the source code exactly as per your requirements. Let me know if you have questions. Regards, Ibrahim
