Discontinuous mode is enabled for regular +group channel conversion and configured to convert one regular channel on each +external trigger. + +ADC1 is configured to start regular group channel conversion on EXTI11 event. +On detection of the first rising edge on PE.11 pin (PF.11 pin for High-Density Value line), +the conversion of the first regular channel (ADC channel4) is done and its converted +value is transferred by DMA to ADC_RegularConvertedValueTab table. On the following edge +detection, the second regular channel (ADC channel14) is automatically converted and +its converted value is stored by DMA in the same table. The number of transmitted data +by DMA, in this example is limited to 64 data. + +The procedure is repeated for both regular channels on each EXTI11 event. +ADC1 is configured to start injected group channel conversion on EXTI15 event. +On detection of the first rising edge on PE.15 pin all selected injected channels, which +are two in this example (ADC channel11 and channel12), are converted and an interrupt +is generated on JEOC flag rising at the end of all injected channels conversion. +Both injected channels converted results are stored in ADC_InjectedConvertedValueTab +table inside the interrupt routine. +The procedure is repeated for injected channels on each EXTI15 event. +The ADC1 clock is set to 12 MHz on Value line devices and to 14MHz on other +devices. + +@par Directory contents + + - ADC/ExtLinesTrigger/stm32f10x_conf.h Library Configuration file + - ADC/ExtLinesTrigger/stm32f10x_it.c Interrupt handlers + - ADC/ExtLinesTrigger/stm32f10x_it.h Interrupt handlers header file + - ADC/ExtLinesTrigger/system_stm32f10x.c STM32F10x system source file + - ADC/ExtLinesTrigger/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 known voltage, between 0-3.3V, to ADC Channel14 mapped on pin + PC.04 (potentiometer RV2), ADC Channel4 mapped on pin PA.04, ADC Channel11 + mapped on pin PC.01 and ADC Channel12 mapped on pin PC.02. + - Connect a push-button to pin PE.11 (EXTI Line11) and another push-button + to pin PE.15 (EXTI Line15). + @note Make shure that jumper JP3 is open. + + - STM32100E-EVAL Set-up + - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1), ADC Channel4 mapped on pin PA.04, ADC Channel11 + mapped on pin PC.01 and ADC Channel12 mapped on pin PC.02. + - Connect a push-button to pin PF.11 (EXTI Line11) and another push-button + to pin PE.15 (EXTI Line15). + + - STM3210C-EVAL Set-up + - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1), ADC Channel4 mapped on pin PA.04, ADC Channel11 + mapped on pin PC.01 and ADC Channel12 mapped on pin PC.02. + - Connect a push-button to pin PE.11 (EXTI Line11) and another push-button + to pin PE.15 (EXTI Line15). + + - STM3210E-EVAL Set-up + - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1), ADC Channel4 mapped on pin PA.04, ADC Channel11 + mapped on pin PC.01 and ADC Channel12 mapped on pin PC.02. + - Connect a push-button to pin PE.11 (EXTI Line11) and another push-button + to pin PE.15 (EXTI Line15). + + - STM3210B-EVAL Set-up + - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin + PC.04 (potentiometer RV1), ADC Channel4 mapped on pin PA.04, ADC Channel11 + mapped on pin PC.01 and ADC Channel12 mapped on pin PC.02. + - Connect a push-button to pin PE.11 (EXTI Line11) and another push-button + to pin PE.15 (EXTI Line15). + +@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. + + *
