STM32 Variant HAL

Name

CYGPKG_HAL_CORTEXM_STM32 -- eCos Support for the STM32 Microprocessor Family

Description

The ST STM32Fxxxx series of Cortex-M microcontrollers is supported by eCos with an eCos processor variant HAL and a number of device drivers supporting most of the on-chip peripherals. These include device drivers for the on-chip flash, serial, I²C, SPI, MMC/SD, Ethernet, CAN, USB OTG HS and FS, ADC, RTC/wallclock and watchdog devices. In addition it provides common functionality and definitions that STM32 based platform ports may require, as well as definitions useful to application developers.

This documentation covers the STM32 functionality provided but should be read in conjunction with the specific HAL documentation for the platform port. That documentation will cover issues that are platform-specific and are not covered here, and may also describe differences that override or supersede what the STM32 variant HAL provides. The areas that are specific to platform HALs and not the STM32 variant HAL include:

  • memory map and related configuration and setup

  • Clock parameters

  • GPIO setup

  • Any special handling for external interrupts, or additional interrupts

  • Diagnostic I/O baud rates

  • Additional diagnostic I/O devices, if any

  • LED/LCD control
