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 IAR Embedded Workbench IDE JLINK for ARM processors Does anybody knows this issue or knows what happens with TIM4 in this device???

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 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);

can you try the TIM example 8 from the ''ARM-based 32-bit MCU STM32F101xx and STM32F103xx firmware library''. It uses the TIM4 and it works fine.

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: Fri Apr 25 15:20:26 2008: DLL version: V3.80c, compiled Apr 9 2008 18:56:00 Fri Apr 25 15:20:26 2008: Firmware: J-Link ARM V6 compiled Mar 3 2008 18:04:42 Fri Apr 25 15:20:26 2008: JTAG speed is initially set to: 32 kHz Fri Apr 25 15:20:26 2008: TotalIRLen = 9, IRPrint = 0x0011 Fri Apr 25 15:20:26 2008: Found Cortex-M3, Little endian.

Can you share your project

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

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); }

To avoid this problem try to reconfigure your project as in the attached image
