Clock configuration tool for STM32F4xx microcontrollers update History


For more information about this tool please refer to "AN3988 Clock configuration tool for STM32F4xx microcontrollers"  available for download from the STMicroelectronics website at www.st.com.

V1.1.0 / 11-January-2013

Main Changes

  • Support STM32F40xx/41xx devices RevZ, i.e. allow configuration of the Prefetch Buffer
  • Add reference to STM32F427x/437x devices and STM324x7I_EVAL board
  • Support fractional value of HSE (ex. 14.7456MHz) 
  • Support PLL input value below 1 MHz, to be in line with PLL characteristics in latest version of STM32F4xx datasheet
  • system_stm32f4xx.c
    • License disclaimer text update and add link to the License file on ST Internet
    • Prefetch Buffer enabled
    • SystemInit_ExtMemCtl() function
      • Add configuration of missing FSMC address and data lines
      • Change memory type to SRAM instead of PSRAM (PSRAM is available only on STM324xG-EVAL RevA) and update timing values
    • Miscellaneous Text update

V1.0.1 / 11-November-2011

Main Changes

  • Bug fix: when selecting HSE as system clock source, in the generated system_stm32f4xx.c file the PLL is enabled and used instead as system clock source.

V1.0.0 / 05-October-2011

Main Changes

  • First official release for STM32F4xx devices
