STM32F4Discovery Board STM32 L Discovery Board



General Information

The STM 32 Discovery board come with a large number of connection pins and are a family of microcontrollers from STMicroelectronics.

The STM32 Discovery boards are powerful and inexpensive, compared to other boards (like the ATMega), but the lack of free available programmers makes them less attractive. A free setup requires quite a bit of tinkering to get it to work Eclipse Example here. Commercial so-called development toolchains (a toolchain is a set of tools used to create a program, consisting of a compiler and a linker, etc.) that are supported are (from the official manual):

The STM32F4 comes with an accelerometer and a digital microphone, and the STM32 L Discovery Board comes with a linear touch sensor and a 6 character LCD display for numbers and letters.
