Easy-to-use firmware libraries for STM32

The standard firmware library for the STM32 ARM™ Cortex-M3™ core-based microcontrollers is complete package consisting of device drivers for all of the standard device peripherals. Each device driver includes a set of functions covering full peripheral functionality. The source code, developed in C language, is highly documented and thoroughly tested.

Links below connect to example folder. The package contains the following examples:

Note: These examples run on STMicroelectronics STM3210B-EVAL board and can be easily tailored to any other hardware.

       
ADC Example1 Use the ADC and DMA to transfer continuously converted data from ADC to a data buffer.
  Example2 Convert ADC regular group channels continuously using TIM1 external trigger and injected group channels using the auto-injected feature.
  Example3 Use the ADC analog watchdog to guard continuously an ADC channel.
  Example4 Trigger ADC regular and injected groups channel conversion using two external line event.
  Example5 Use ADC1 and ADC2 in regular simultaneous dual mode.
       
BKP Example1 Write/read data to/from Backup data registers and demonstrates the Tamper detection feature.
  Example2 Store user data in the Backup data registers.
       
CAN Example1 Set a communication with the bxCAN in loopback mode
ARM7 STR7 Software Library Folder Example
CortexM3 Example1 Use CortexM3 Bit-Band access to perform atomic read-modify-write and read operations on a variable in SRAM.
  Example2 Modify CortexM3 Thread mode privilege access and stack.
       
DEBUG Example1 Demonstrates the STM32F10x Firmware Library DEBUG mode. When the Debug mode is selected, the assert macro is expanded and run time checking is enabled in the firmware library code. The run-time checking allows checking that all the library functions input value lies within the parameter allowed values.
       
DMA Example1 Use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM).
  Example2 Use two DMA channels to transfer a data buffer from memory to I2C2 through I2C1.
  Example3 Use four DMA channels to transfer a data buffer from memory to SPI2 through SPI1 and a second data buffer from memory to SPI1 through SPI2 in full-duplex mode.
  Example4 Use a DMA channel to transfer continuously a data from a peripheral (ADC) to another (TIM1) supporting DMA transfer.
       
EXTI Example1 Configure an external interrupt line.
       
FLASH Example1 Program the STM32F10x FLASH.
  Example2 Enable and disable the write protection for the STM32F10x FLASH.
       
GPIO Example1 Use the GPIO BSRR (Port bit set/reset register) and BRR (Port bit reset register) for IO toggling. These registers allow modifying only one or several GPIO pins in a single atomic write access.
  Example2 Use the JTAG IOs as standard GPIOs and gives a configuration sequence.
       
I2C Example1 Transfer a data buffer from I2C1 to I2C2 using interrupts.
  Example2 Transfer two data buffer from I2C1 to I2C2 through its two addresses in the same application.
  Example3 Send an ARP command from I2C1 to I2C2 in SMBus mode.
  Example4 Transfer a data buffer from I2C1 to I2C2 in 10-bit addressing mode..
  Example5 Use the I2C firmware library and an associate I2C EEPROM driver to communicate with an M24C08 EEPROM.
       
IWDG Example1 Reload at regulate period the IWDG counter using the SysTick interrupt.
       
NVIC Example1 Use of the Nested Vectored Interrupt Controller (NVIC) and priority mechanism (PreemptionPriority , SubPriority)
  Example2 Use of the Nested Vectored Interrupt Controller (NVIC) and IRQ Channels configuration
  Example3 Use of the Nested Vectored Interrupt Controller (NVIC) and system handlers
  Example4 Use the NVIC firmware library to demonstrate the Cortex-M3 low power modes capabilities (WFE and WFI).
  Example5 Enter the system to WFI mode with DMA transfer enabled and wake-up from this mode by the DMA End of Transfer interrupt.
  Example6 Use the NVIC firmware library to set the CortexM3 vector table in a specific address other than default.
This can be used to build program which will be loaded into Flash memory by an application previously programmed in the sector0 of the Flash memory. Such application can be In-Application Programming (IAP, through USART) or Device Firmware Upgrade (DFU, through USB).
       
PWR Example1 Enter the system to STOP mode and wake-up using EXTI Line interrupts. The EXTI Line sources are PB.09 and RTC Alarm.

SPI Example1 Set a communication between the two SPIs in full-duplex mode and performs a transfer from Master to Slave and then Slave to Master in the same application with software NSS management.
  Example2 Set a communication between two SPIs in simplex mode and performs a data buffer transfer from Master to Slave
using TxE interrupt for master and RxNE interrupt for slave.
  Example3 set a communication between two SPIs in full-duplex mode and performs a transfer from Master to Slave and
Slave to Master followed by CRC transmission.
  Example4 Set a communication between the two SPIs in simplex mode and performs a transfer from Master in polling mode to the Slave in DMA receive mode. The NSS pin is managed by hardware.
