The ADC1 is configured to convert continuously channel14. Each time an end of conversion occurs the DMA transfers, in circular mode, the converted data from ADC1 DR register to the ADCConvertedValue variable. The ADC1 clock is set to 12 MHz on Value line devices and to 14MHz on other devices. @par Directory contents - ADC/ADC1_DMA/stm32f10x_conf.h Library Configuration file - ADC/ADC1_DMA/stm32f10x_it.c Interrupt handlers - ADC/ADC1_DMA/stm32f10x_it.h Interrupt handlers header file - ADC/ADC1_DMA/system_stm32f10x.c STM32F10x system source file - ADC/ADC1_DMA/main.c Main program @par Hardware and Software environment - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density, XL-Density, 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) - STM3210C-EVAL Set-up - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin PC.04 (potentiometer RV1) - STM3210E-EVAL Set-up - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin PC.04 (potentiometer RV1) - STM3210B-EVAL Set-up - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin PC.04 (potentiometer RV1) @par How to use it ? In order to make the program work, you must do the following : - Create a project and setup all project configuration - Add the required Library files : - stm32f10x_adc.c - stm32f10x_dma.c - stm32f10x_gpio.c - stm32f10x_rcc.c - Edit stm32f10x.h file to select the device you are working on. - Use STM32F10x system source file "system_stm32f10x.c" provided with this example. @b Tip: You can tailor the provided project template to run this example, for more details please refer to "stm32f10x_stdperiph_lib_um.chm" user manual; select "Peripheral Examples" then follow the instructions provided in "How to proceed" section. - Link all compiled 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 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. * <h3><center>&copy; COPYRIGHT 2010 STMicroelectronics</center></h3> */
