TIM1_CH1 is configured +to generate a PWM signal on its output. +The dedicated DMA1 channel5 is configured to transfer in circular mode the last ADC +channel14 converted value to the TIM1_CCR1 register. The DMA channel request is driven +by the TIM1 update event. The duty cycle of TIM1_CH1 output signal is then changed +each time the input voltage value on ADC channel14 pin is modified. +The duty cycle variation can be visualized on oscilloscope on the TIM1_CH1 pin +PA.08 while changing the analog input on ADC channel14 using the potentiometer. + +@par Directory contents + + - DMA/ADC_TIM1/stm32f10x_conf.h Library Configuration file + - DMA/ADC_TIM1/stm32f10x_it.c Interrupt handlers + - DMA/ADC_TIM1/stm32f10x_it.h Interrupt handlers header file + - DMA/ADC_TIM1/main.c Main program + - DMA/ADC_TIM1/system_stm32f10x.c STM32F10x system source file + +@par Hardware and Software environment + + - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density, + XL-Density, High-Density Value line, Medium-Density Value line, Low-Density + and Low-Density Value line Devices. + + - This example has been tested with STMicroelectronics STM32100B-EVAL (Medium-Density + Value line), STM3210C-EVAL (Connectivity line), STM3210E-EVAL (High-Density and + XL-Density) and STM3210B-EVAL (Medium-Density) evaluation boards and can be easily + tailored to any other supported device and development board. + + - STM32100B-EVAL Set-up + - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin + PC.04 (potentiometer RV2) + - Connect an oscilloscope to TIM1_CH1 (PA.08) pin + + - STM3210C-EVAL Set-up + - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1) + - Connect an oscilloscope to TIM1_CH1 (PA.08) pin + + - STM3210E-EVAL Set-up + - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1) + - Connect an oscilloscope to TIM1_CH1 (PA.08) pin + + - STM3210B-EVAL Set-up + - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1) + - Connect an oscilloscope to TIM1_CH1 (PA.08) pin + + - STM32100E-EVAL Set-up + - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1) + - Connect an oscilloscope to TIM1_CH1 (PA.08) pin + + +@par How to use it ? + +In order to make the program work, you must do the following : + - Copy all source files from this example folder to the template folder under + Project\STM32F10x_StdPeriph_Template + - Open your preferred toolchain + - Rebuild all files and load your image into target memory + - Run the example + +@note + - Low-density Value line devices are STM32F100xx microcontrollers where the + Flash memory density ranges between 16 and 32 Kbytes. + - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx + microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. + - Medium-density Value line devices are STM32F100xx microcontrollers where + the Flash memory density ranges between 64 and 128 Kbytes. + - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx + microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. + - High-density Value line devices are STM32F100xx microcontrollers where + the Flash memory density ranges between 256 and 512 Kbytes. + - High-density devices are STM32F101xx and STM32F103xx microcontrollers where + the Flash memory density ranges between 256 and 512 Kbytes. + - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where + the Flash memory density ranges between 512 and 1024 Kbytes. + - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers. + + *
