ADCs

In the same way, Medium-density devices feature two ADCs (ADC1 and ADC2) that share

the same IRQ channel. High-density devices have an additional ADC (ADC3) with a

separate IRQ channel.

For this reason, the ADC1 and ADC2 IRQ channel names were modified in

stm32f10x_nvic.c

/stm32f10x_nvic.h, as detailed in Table 2 below.

The example below shows how to configure and enable the ADC1 (or ADC2) IRQ channel

using FWLib V1.0:

/* Configure and enable ADC1 IRQ channel */

NVIC_InitStructure.NVIC_IRQChannel = ADC_IRQChannel;

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;

NVIC_Init(&NVIC_InitStructure);

In V2.0, you simply need to change “ADC_IRQChannel” by “ADC1_2_IRQChannel”.

/* Configure and enable ADC1 IRQ channel */

NVIC_InitStructure.NVIC_IRQChannel = ADC1_2_IRQChannel;

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;

NVIC_Init(&NVIC_InitStructure);

Note:

The corresponding DMA and ADC ISR names have also been modified in

stm32f10_it.c

/.stm32f10_it.h.

2.2.2

TIM

In FWLib V1.0 the timer peripherals are covered by two drivers:

●

stm32f10x_tim.c

/stm32f10x_tim.h: they cover the functionality of general-

purpose timers (TIM2, TIM3 and TIM4). The function format in this driver is as follows:

TIM_FunctionName(TIMx, param1, param2,...)

e.g.: TIM_ITConfig(TIM_TypeDef* TIMx, u16 TIM_IT, FunctionalState NewState)

●

stm32f10x_tim1.c

/stm32f10x_tim1.h: they cover the functionality of the

advanced-control timer (TIM1). This driver provides the same set of functions as

stm32f10x_tim.c

/stm32f10x_tim.h plus dedicated functions to cover addtional

TIM1 features (PWMI mode, complementary PWM with dead-time insertion, etc.). The

function format in this driver is as follows:

TIM1_FunctionName(param1, param2,...)

e.g.: TIM1_ITConfig(u16 TIM1_IT, FunctionalState NewState)

In FWLib V2.0, these two drivers have been merged into a single driver,

stm32f10x_tim.c

/stm32f10x_tim.h, that covers all the timers available in High-

density and Medium-density devices: general-purpose timers (TIM2, TIM3, TIM4 and TIM5),

advanced-control timers (TIM1 and TIM8) and basic timers (TIM6&7).

This change affects only application code based on the

stm32f10x_tim1.c

/stm32f10x_tim1.h driver. The set of functions for TIM1 are the

Table 2.
