STM32L1x standard firmware library configuration

The stm32l1xx_conf.h file of the STM32L1x standard firmware library allows you to

configure the library by enabling the peripheral functions used by the application.

The header files of library modules are included in the stm32l1xx_conf.h file as listed bellow.

#include stm32l1xx_adc.h

#include stm32l1xx_exti.h

#include stm32l1xx_flash.h

#include stm32l1xx_gpio.h

#include stm32l1xx_syscfg.h

#include stm32l1xx_lcd.h

#include stm32l1xx_pwr.h

#include stm32l1xx_rcc.h

#include stm32l1xx_rtc.h

#include "misc.h"

The corresponding library modules has to be present in the project for successful

compilation and linking.

Application software flow

2.3.1

Main application

After powering up the STM32L1xx DISCOVERY, the initialization of the peripherals and LCD

display is performed and then the application immediately checks whether the USER push-

button is pressed. If pressed, then the application goes to the Bias current record operation.

the user presses the USER key for more than 3 seconds, then the application enters

manufacturing test. To exit manufacturing test, the application needs to be restarted by

pressing the RESET button.

2.3.2

When Demo mode is launched, it starts displaying a welcome message and then, after a

the USER pushbutton (as described in Section 1.5.1).

These functions are mainly divided in 2 steps:

•

Configuring the device according to the selected power mode

•

The Demo mode sequence is as follows:
