The STM32 F7-series is a group of STM32 microcontrollers based on the ARM Cortex-M7F core. Many of the F7 series are pin-to-pin compatible with the STM32 F4-series. Core: ARM Cortex-M7F core at a maximum clock rate of 216 MHz. Many of STM32F76xxx and STM32F77xxx models have a digital filter for sigma-delta modulators (DFSDM) interface. [31]

A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in personal computers , servers and embedded systems , RTCs are present in almost any electronic device which needs to keep accurate time of day .
It is fitted with a Lipo charge controller and 12 Grove sockets for plug and play prototyping. It runs at 3.3 V and 8 MHz. It also comes with a DS3231 Real Time Clock and 16 Mbit serial flash for data logging. Its "bee" socket can use a range of different modules, like Xbee, RFbee, Bluetoothbee and GPRSbee to make the board communicate.
The frequency of the clock tick depends on the desired tick resolution of an application. Tick sources can be obtained by dedicating a hardware timer, or by generating an interrupt from an alternating current (AC) power line (50 or 60 Hz) signal. This periodic time source is termed a clock tick. [18] After a clock tick is determined, tasks can be:
This is a list of real-time operating systems (RTOSs). This is an operating system in which the time taken to process an input stimulus is less than the time lapsed until the next input stimulus of the same type.
Real-time clocks are electronic devices designed to provide system time, and thereby wall-clock time, to a computer system. (Contrast this with clock signals, designed to provide timing for electronics themselves.)
ChibiOS/RT is designed for embedded applications on microcontrollers of 8-, 16-, and 32-bits.Size and execution efficiency are the main project goals. [3] As reference, the kernel size can range from a minimum of 1.2 KiB up to a maximum of 5.5 KiB with all the subsystems activated on a STM32 Cortex-M3 processor.
