CMSIS-Compliant Device Files
|
||
|
|
============================
|
||
|
|
The code also includes the CMSIS-compliant interface to the
|
||
|
|
STM32L053xx MCU files:
|
||
|
|
|
||
|
|
stm32l1xx.h
|
||
|
|
system_stm32l1xx.h
|
||
|
|
system_stm32l1xx.c
|
||
|
|
arm\startup_stm32l1xx.s
|
||
|
|
gcc\startup_stm32l1xx.c
|
||
|
|
iar\startup_stm32l1xx.s
|
||
|
|
|
||
|
|
|
||
|
|
Adjusting the CPU Clock Speed
|
||
|
|
=============================
|
||
|
|
The current setting is to run at 2MHz from the MSI (internal oscillator),
|
||
|
|
but the CPU clock speed can be modified by editing the file
|
||
|
|
system_stm32l1xx.c. Ther file system_stm32l1xx.c.pll provides an example
|
||
|
|
of clock setting using the PLL driven from the MSE.

|
|
NOTE:
|
||
|
|
The NUCLEO boards have a wide range of possible clock selections, depending
|
||
|
|
on the solder bridge configuration. Please see Chapter 5.7 "OSC clock" in
|
||
|
|
the STM32 NUCLEO Boards User Manual (ST document UM1724) for more information.
