A filter is a useful tool for removing unwanted signals from a sensor measurement. There is complicated math behind how they work, but you just need to know a simple formula to use them in many embedded designs.
Get the CoAction Hero with Stratify OS pre-installed
The CoAction Hero is an ARM Cortex M3 development board. It has Stratify OS pre-installed which gives you easy-to-use multi-threading, hardware abstraction and debugging all by simply connecting a USB cable.
What's a Microcontroller
A microcontroller is a microprocessor with integrated hardware peripherals (such as SPI, UART, I2C, ADC) and memory (usually RAM and flash). Compared to microprocessors, they boot instantly, consume less power and are easier to integrate into products but typically present firmware development challenges.
Building and Installing a Cortex-M Compiler on Mac, Windows or Linux
GCC is a open source C compiler which can be downloaded, compiled, and installed on Mac OS X. It is the compiler of choice for Stratify OS, and an excellent general purpose ARM Cortex-M3 compiler.
Applications without an MMU
One of Stratify OS’s biggest software challenges is providing the ability to install applications separately from the OS–without an MMU. Overcoming this challenge contributes to both ease-of-use and portability. By installing just the application, you save the programmer the work of integrating and compiling the OS with the application. The programmer can also distribute the binary file to other devices running Stratify OS. In the MMU-free world, these features are only available on uCLinux and now Stratify OS.
Order of Operations Reference
The following is a list of the C order of operations from highest precendence to lowest.
Operators within the same group have equal precendence and evaluate lefto-to-right or right-to-left as indicated.
