# Release Notes for STM322xG_EVAL Examples Copyright 2017 STMicroelectronics
## Update History ### V1.1.3 / 17-March-2017 Main Changes General examples projects update to be aligned with new HAL SD and BSP Drivers implementation Update system_stm32f2xx.c file in all projects to be aligned with latest version of CMSIS STM32F2xx device implementation Update stm32f2xx_hal_conf.h file in all projects to be aligned with new conf_template.h Update DMA_FLASHToRAM example to use FIFO mode instead of direct mode for memory to memory transfer Update FMC_SRAM example to enhance implementation ### V1.1.2 / 01-July-2016 Main Changes stm32f2xx_hal_conf.h: Adjust the HSE Start-up Timeout value: 100ms instead of 5s Add new define USE_SPI_CRC for code cleanup when the CRC calculation is disabled Add new define for the LSE start-up Timeout: LSE_STARTUP_TIMEOUT HAL_TimeBase Update to use new HAL TimeBase driver template stm32xxx_hal_timebase_time Add two new time base examples Update HAL_TimeBase example to use TIM HW as time base source instead of Systick Update IWDG example to be in line with latest updates done on HAL IWDG drivers Remove the HAL_IWDG_Start function in the main.c file Update WWDG examples to be in line with latest updates done on HAL WWDG drivers Remove the HAL_WWDG_Start and update the HAL_WWDG_Refresh functions in the main.c file Remove HAL_WWDG_MspDeInit function from stm32f2xx_hal_msp.c file Update DMA_FLASHToRAM example to use HAL_DMA_RegisterCallback() function Rework I2C_TwoBoards_AdvComIT example following changes in latest HAL version Update to allow master to restart communication when slave doesn't acknowledge its address Update SPI DMA example to manage SPI peripheral errors during DMA process ### V1.1.1 / 20-November-2015 Main Changes ADC_TripleModeInterleaved example: update to use ADC triple mode instead of ADC dual mode ### V1.1.0 / 09-October-2015 Main Changes Add the support System Workbench for STM32 (SW4STM32) toolchain All projects updated following changes in latest version of HAL and Middlewares Add 29 new Examples: ADC\ADC_InjectedConversion_Interrupt ADC\ADC_RegularConversion_DMA ADC\ADC_RegularConversion_Interrupt ADC\ADC_TripleModeInterleaved CAN\CAN_LoopBack CRYP\CRYP_AES_DMA CRYP\CRYP_TDES_DMA DCMI\DCMI_SnapshotMode DMA\DMA_FIFOMode HAL\HAL_TimeBase HASH\HASH_HMAC_SHA1MD5 PWR\PWR_BOR PWR\PWR_PVD RTC\RTC_Alarm RTC\RTC_TimeStamp SMARTCARD\SMARTCARD_T0 TIM\TIM_6Steps TIM\TIM_7PWMOutput TIM\TIM_CascadeSynchro TIM\TIM_ComplementarySignals TIM\TIM_DMABurst TIM\TIM_Encoder TIM\TIM_ExtTriggerSynchro TIM\TIM_InputCapture TIM\TIM_OCActive TIM\TIM_OCInactive TIM\TIM_OCToggle TIM\TIM_ParallelSynchro UART\UART_Hyperterminal_IT Common update for all Examples Update EWARM startup file for all projects to cope with compiler enhancement of the V7.x version Update “stm32f2xx_hal_conf.h” to be in line with HAL V1.1.0: add new defines LSI_VALUE, LSE_VALUE and TICK_INT_PRIORITY Update “stm32f2xx_it.c”: add the include of “main.h” before the “stm32f2xx_it.h”, in order to provide access to CMSIS device file via “stm32f2xx_hal.h” Miscellaneous source code comments update Force initialization of all PPP Init structure's field before calling HAL_PPP_Init() API CRYP examples: update to initialize the new filed 'Instance' ADC_TriggerMode: update to set ADC_EOC_SEQ_CONV value instead of ENABLE as EOCSelection parameter BSP Example: remove the call of BSP_EEPROM_WaitEepromStandbyState() function, it's not useful to be called by the application code (now it's declared as static function within the EEPROM BSP driver) FLASH_EraseProgram: Add a note about the need to flush the data and/or instruction cache after Sector Erase operation, if they was previously enabled Update to reset data and instruction cash memories after flash erase CORTEXM_ModePrivilege: add ISB instruction to flush the pipeline after MSR instruction to modify CONTROL register I2S_Audio Retrieve audio data from a storage unit (Internal Flash for Instance) through an explicit GetData method. Can be easily adapted to use data from any storage unit (USB, uSD...) Use an elastic buffer to manage double buffer mechanism using the DMA circular mode and the half and complete transfer callbacks Use the buffer size in byte instead of half-word when calling the BSP_AUDIO_OUT_Play() function Miscellaneous update UART_HyperTerminal_DMA update following the change done in UART driver to fix the DMA transmit process (the code has been updated to avoid waiting on TC flag under DMA ISR, UART TC interrupt is used instead): in stm32f2xx_hal_msp.c file, configure and enable the USART IRQ in HAL_UART_MspInit() function In stm32f2xx_it.c file, USARTx_IRQHandler() function: add a call to HAL_UART_IRQHandler() function Add display on the Hyperterminal of the actions that need to be done by user PWR_STANDBY Update to avoid configuring the RTC each time the device resumes from Standby mode, since the RTC configuration is kept in Standby mode. Add safety wake up sequence by following errata sheet recommendation Add enable backup domain before clearing RTC flags PWR_CurrentConsumption: update following latest change in HAL V1.2.0 SleepMode_Measure(): add HAL_SuspendTick() function before entering in Sleep mode and add HAL_ResumeTick() after exit from this mode StandbyMode_Measure(), StandbyRTCMode_Measure() and StandbyRTCBKPSRAMMode_Measure(): update STANDBY mode entry sequence as follows: Disable all used wakeup sources Clear all related wakeup flags Re-enable all used wakeup sources Enter the standby mode Update to call the BSP_PB_Init() function outside the waiting loop RCC_ClockConfig In main.c file : add the default HSI calibration value “RCC_OscInitStruct.HSICalibrationValue = 0x10;” in function SystemClockHSI_Config() TIM_PWMInput: change the name of example from “TIM_PWMIntput” to “TIM_PWMInput” TIM_TimeBase: In main.c file: initializes the LEDs before using them In main.c file: remove the following duplicated line “uwPrescalerValue = (uint32_t)((SystemCoreClock /2)/10000)-1;” Miscellaneous update on BSP, MPU and RTC Tamper examples Development Toolchains and Compilers IAR Embedded Workbench for ARM (EWARM) toolchain v7.40.1 RealView Microcontroller Development Kit (MDK-ARM) toolchain v5.16 Atollic TrueSTUDIO STM32 (TrueSTUDIO) toolchain v5.3.1 System Workbench for STM32 (SW4STM32) toolchain V1.3.0 + ST-Link Supported Devices and EVAL boards STM32F217xx/215xx/207xx/205xx devices and STM322xG_EVAL board RevC Known Limitations None ### V1.0.0 / 07-March-2014 Main Changes First official release ## License Licensed under MCD-ST Liberty SW License Agreement V2, (the "License"); You may not use this package except in compliance with the License.
