HAL to StdPeriph_Lib list of changes

3.3

HAL peripheral driver update

This section provides the compatibility guideline for the standard STM32W108xx IP drivers

between the HAL and the StdPeriph_Lib.

3.3.1

ADC

In addition to the high-level ADC API provided in the Hardware Abstraction Layer (HAL),

some additional/basic ADC APIs are provided by the STM32W108xx standard library

drivers. These APIs are summarized in the following table:

Table 8. STM32W108xx ADC driver overview

StdPeriph_Driver API

Functionality description

ADC_DeInit()

Deinitializes ADC peripheral registers to their default

reset values

ADC_Init()

Initializes the ADC peripheral according to the specified

parameters in the ADC_InitStruct

ADC_StructInit()

Fills each ADC_InitStruct member with its default value

ADC_Cmd(FunctionalState NewState)

Enables or disables the specified ADC peripheral

ADC_ChannelConfig(uint32_t

ADC_Channels)

Configures the ADC channels

ADC_DMA_ChannelLoadEnable(void)

Enables specified ADC DMA Channel

ADC_DMA_ChannelReset(void)

Resets specified ADC DMA

ADC_DMA_Config(uint32_t

ADC_DMABeg, uint32_t ADC_DMASize)

Selects the specified DMA configuration

ADC_DMA_GetNextAddress(void)

Gets the location that will be written next by the DMA

ADC_DMA_GetCounter(void)

Gets the number of 16-bit conversion results that have

been written to the buffer

ADC_ITConfig(uint32_t ADC_IT,

FunctionalState NewState)

Enables or disables the specified ADC interrupts

ADC_DMA_GetFlagStatus(uint32_t

ADC_DMA_FLAG)

Checks whether the specified ADC interrupt has

occurred or not

ADC_GetITStatus(uint32_t ADC_IT)

Checks whether the specified ADC pending interrupt

has occurred or not

ADC_ClearITPendingBit(uint32_t ADC_IT) Clears the ADC’s interrupt pending bits
