The 32bits conversion +result is then stored on ADC1 DR register. The DMA will transfer this data which +will be stored ADC_DualConvertedValueTab table. Consecutively to those conversion, +channel17 is converted on ADC1 and channel12 on ADC2. The combined conversion +result is also transferred by DMA to the same destination buffer. + +The same procedure is repeated until the specified number of data to be transferred +by DMA is reached. + +The ADCs clocks are set to 14 MHz. + +@par Directory contents + + - ADC/RegSimul_DualMode/stm32f10x_conf.h Library Configuration file + - ADC/RegSimul_DualMode/stm32f10x_it.c Interrupt handlers + - ADC/RegSimul_DualMode/stm32f10x_it.h Interrupt handlers header file + - ADC/RegSimul_DualMode/system_stm32f10x.c STM32F10x system source file + - ADC/RegSimul_DualMode/main.c Main program + +@par Hardware and Software environment + + - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density, + XL-Density and Low-Density Devices. + + - This example has been tested with STMicroelectronics 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. + + - STM3210C-EVAL Set-up + - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1), ADC Channel11 mapped on pin PC.01 and ADC + Channel12 mapped on pin PC.02. + + - STM3210E-EVAL Set-up + - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1), ADC Channel11 mapped on pin PC.01 and ADC + Channel12 mapped on pin PC.02. + + - STM3210B-EVAL Set-up + - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1), ADC Channel11 mapped on pin PC.01 and ADC + Channel12 mapped on pin PC.02. + +@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 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>© COPYRIGHT 2011 STMicroelectronics</center></h3> + */
