STM3240_41_G_EVAL Evaluation Board Drivers update History

Important Note: stm324xg_audio_recorder.c/.h, stm324xg_audio_codec.c/.h and stm324xg_clk_synthesizer_cs2200.c/.h drivers are customized for the purpose of the "STM32 USB Device Audio Streaming" Example and intended for use ONLY in this scope.

V1.2.0 / 13-February-2012

Main Changes

  • stm324xg_clk_synthesizer_cs2200.c/.h
    • Update the CS2200 external clock synthesizer configuration to have the reference clock input set to 42 MHz instead of 40 MHz, ans thus can run at STM32F4 maximum frequency 168 MHz. The reference clock input is generated from STM32F4 MCO1 clock which is equal to PLLCLK / 4 =  168 MHz / 4 = 42 MHz

V1.1.0 / 27-January-2012

Main Changes

  • Add drivers to manage Audio components provided within STM324xG-EVAL evaluation board
    • stm324xg_audio_recorder.c/.h: driver for audio recording using ADC and TIM timer
    • stm324xg_audio_codec.c/.h: driver for CS43L22 Audio Codec
    • stm324xg_clk_synthesizer_cs2200.c/.h: driver for CS2200 external clock synthesizer controller
    • Note: These drivers are customized for the purpose of the "STM32 USB Device Audio Streaming" Example and intended for use ONLY in this scope.

V1.0.1 / 28-December-2011

Main Changes

  • All source files: update disclaimer to add reference to the new license agreement
  • stm324xg_eval_lcd.c
    • Remove “static” from TextColor and BackColor variables declaration (need to be changed from other application modules) 
  • stm324xg_eval_ioe.h
    • Add conditional compilation on the default DMA stream(s) used for I2C1 Tx and Rx transfers, to allow user to change them from application level.
  • stm322xg_eval_sdio_sd.h
    • SD_CardInfo structure, define CardCapacity variable as 64-bit long (instead of 32-bit)  to support SDHC memory cards with capacity greater than 4 GB.
  • stm324xg_eval_fsmc_sram.c
    • Add IOs config of missing FSMC address lines (FSMC_A21, FSMC_A22 and FSMC_A23).

V1.0.0 / 30-September-2011

Main Changes

  • First official release for STM3240_41_G_EVAL board RevB drivers
  • stm322xg_eval_lcd.c: increase FSMC AddressSetupTime value from 4 to 5 to be compliant with some LCD access timing

V1.0.0RC1 / 26-September-2011

Main Changes

  • Official version (V1.0.0) Release Candidate1 for STM3240_41_G_EVAL board RevB drivers
