TIM4 do not work in STM32F103V8T6

Posted on May 17, 2011 at 12:31

hy!

i know, my fault, i copied the wrong part of my code.

I tried to initialize all 4 timers.

1 - 3 worked fine, only 4th doesn't work.

I took a look at the registers of TIM4 with the debugger when this line appears

Code:

TIM_TimeBaseInit(TIM4, &TIM_TimeBaseStructure);

and nothing happens there.

it looks like TIM4 isn't there!

whole code is now:

Code:

// TIM4 clock enable 24MHz

RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM4, ENABLE);

// Time base configuration

TIM_TimeBaseStructure.TIM_Period = TIM4_Freq_16kHz;

TIM_TimeBaseStructure.TIM_Prescaler = 1;

TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;

TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;

TIM_TimeBaseInit(TIM4, &TIM_TimeBaseStructure);

TIM_ITConfig(TIM4,TIM_IT_Update, ENABLE);

// Enable TIM4 global Interrupt

NVIC_InitStructure.NVIC_IRQChannel = TIM4_IRQChannel;

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;

NVIC_Init(&NVIC_InitStructure);

// TIM enable counter

TIM_Cmd(TIM4, ENABLE);

Take a look at this line of your code

NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQChannel;

You have enabled the TIM3 interrupt not Timer 4

This could be a problem....

Hy!

i try to use timer 4 (TIM4) in my project, but it doesn't work.

Till now i tried all other timers (Timer1, Timer2&3) and they are working fine.

I used the same initialization routines for Timer4 as for the others:

Code:

// TIM4 clock enable 24MHz

RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM4, ENABLE);

// Time base configuration

TIM_TimeBaseStructure.TIM_Period = TIM4_Freq_16kHz;

TIM_TimeBaseStructure.TIM_Prescaler = 1;

TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;

TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;

TIM_TimeBaseInit(TIM4, &TIM_TimeBaseStructure);

TIM_ITConfig(TIM4,TIM_IT_Update, ENABLE);

// Enable TIM4 global Interrupt

NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQChannel;

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;

NVIC_Init(&NVIC_InitStructure);

// TIM enable counter

TIM_Cmd(TIM4, ENABLE);

Timer 4 should be available in this device (described in the datasheet).

µC: STM32F103V8

JLINK for ARM processors

Does anybody knows this issue or knows what happens with TIM4 in this device???

i tried the example 8 with the ''GettingStarted'' workspace for IAR Workbench, and it works!

i also checked the registers for TIM4 with debugger and the output pin channel1 of tim4.

it worked fine.

so i checked all my project settings, and did changes at the DEBUGGER -> DOWNLOAD -> Flash loader file.

this was set to ''$TOOLKIT_DIR$\config\flashloader\ST\FlashSTM32F10x.d79'' manually.

i changed it to the ''Default'' setting like in the working workspace (TIM4 example), and now i get crazy errors:

When i try to change to the settings before, the same error occurs.

i don't know what to do now.

i tried 2 boards with my described processor type, and the IAR kickstart kit board, nothing helps!!!

Hy!

Today i did some other tests with my software.

i took another (unflashed) board, and tried my software without enabling the ADC with DMA.

the flashing and debugging with ''IAR workbench'' worked fine!

i repeated that procedure several times without any problem.

Than i tried to enable the ADC with DMA.

The first programming (flashing) was done correctly and all works fine.

but when i try to flash again the same software the described errors appear.

What could be the problem???

my ADC init routine:

Code:

void Analog_Init(void)

{

// Enable DMA clock

RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA, ENABLE);

// Enable ADC1 and GPIOC clock

RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1 | RCC_APB2Periph_GPIOC, ENABLE);

// DMA channel1 configuration ----------------------------------------------

DMA_DeInit(DMA_Channel1);

DMA_InitStructure.DMA_PeripheralBaseAddr = (u32)ADC1_DR_Address;

DMA_InitStructure.DMA_MemoryBaseAddr = (u32)ADC_ConvertedValueTab;

DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;

DMA_InitStructure.DMA_BufferSize = 6;

DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;

DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;

DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_Word;

DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_Word;

DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;

DMA_InitStructure.DMA_Priority = DMA_Priority_High;

DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;

DMA_Init(DMA_Channel1, &DMA_InitStructure);

// Enable DMA Channel1

DMA_Cmd(DMA_Channel1, ENABLE);

// ADC1 configuration ------------------------------------------------------

ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;

ADC_InitStructure.ADC_ScanConvMode = ENABLE;

ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;

ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;

ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;

ADC_InitStructure.ADC_NbrOfChannel = 6;

ADC_Init(ADC1, &ADC_InitStructure);

// ADC1 regular channels configuration

ADC_RegularChannelConfig(ADC1, ADC_Channel_10, 1, ADC_SampleTime_239Cycles5);

ADC_RegularChannelConfig(ADC1, ADC_Channel_11, 2, ADC_SampleTime_239Cycles5);

ADC_RegularChannelConfig(ADC1, ADC_Channel_12, 3, ADC_SampleTime_239Cycles5);

ADC_RegularChannelConfig(ADC1, ADC_Channel_13, 4, ADC_SampleTime_239Cycles5);

ADC_RegularChannelConfig(ADC1, ADC_Channel_14, 5, ADC_SampleTime_239Cycles5);

ADC_RegularChannelConfig(ADC1, ADC_Channel_15, 6, ADC_SampleTime_239Cycles5);

// Enable ADC1 DMA

ADC_DMACmd(ADC1, ENABLE);

// Enable ADC1

ADC_Cmd(ADC1, ENABLE);

// Enable ADC1 reset calibaration register

ADC_ResetCalibration(ADC1);

// Check the end of ADC1 reset calibration register

while(ADC_GetResetCalibrationStatus(ADC1));

// Start ADC1 calibaration

ADC_StartCalibration(ADC1);

// Check the end of ADC1 calibration

while(ADC_GetCalibrationStatus(ADC1));

// Start ADC1 Software Conversion

ADC_SoftwareStartConvCmd(ADC1, ENABLE);

}

hy!

in principle its the same code like in the ''getting started'' example, only with the Example 8 files included.

with my company project i started also with the ''gettingStarted''.

Following peripherals are in use:

ADC with DMA

I2C for Display

I2C for Flash

TIM1 to 3

and some GPIO for keyboard etc.

i recognized the first problems since i included the ADC with DMA!

i don't know if this could be the problem

Thanks, but it didn't work with this settings, because they are already set.

i tried the ''software reset'' and it works!

is it ok to set to ''software reset''?
