其实是可以工作的, 我用的是标准库, 范例用的是官网下载的 ADC 范例 STM32F0xx_StdPeriph_Examples<-- 这一包 无论是 ADC_BasicExample或者 ADC_DMA的ˋ范例 我都能从 Livewatch 来看到我转动 VR 的数值由 0 ~ 3300 做变化 于是我复制了可以工作的范例去到 ST 官网的电机驱动方案的 FOC 4.3的 SDK -STSW-STM32100 这包 (目前已更新到 5.0, 而我用的是 4.3) 但在范例可以工作的ADC-PA5, 却无法在电机库里面运作 ADC1ConvertedValue和 ADC1ConvertedVoltage都是 100 ~ 130 左右跳动, 不会像范例一样有 0 ~ 3300的变化 以下是我贴上来的main.c 其中 PA8,PA9,PA10,PA7,PB0,PB1 用做电机库 PWM工作 PA3 电机库电压采样 PA4 电流采样 在麻烦高手指点一下是否有什么地方需要注意 /* Includes ------------------------------------------------------------------*/ /* Pre-compiler coherency check */ #define PROJECT_CHK #include "CrossCheck.h" #undef PROJECT_CHK #include "MCTuningClass.h" #include "MCInterfaceClass.h" #if defined(PFC_ENABLED) #include "PFCInit.h" #include "PFCApplication.h" #endif #include "MCTasks.h" #include "Parameters conversion.h" #ifdef DUALDRIVE #include "Parameters conversion motor 2.h" #endif #include "Timebase.h" #include "UITask.h" #include "MCLibraryISRPriorityConf.h" #include <stdio.h> #include "stm32f0xx_adc.h" #include "RevupCtrlClass.h" __IO uint16_t ADC1ConvertedValue = 0, ADC1ConvertedVoltage = 0; __IO uint16_t RegularConvData_Tab[4]; #define ADC1_DR_Address 0x40012440 #if (defined(USE_STM32303C_EVAL)) #include "stm32303c_eval.h" #elif USE_EVAL #include "stm32_eval.h" #endif #ifdef USE_STGAP1S #include "GAPApplication.h" #endif #ifdef STSPIN32F0 void STSPIN32F0_Init(void); #endif #define INTERNAL 0 #define EXTERNAL 1 #define STM32F3_64MHZ_INT ((CLOCK_SOURCE == INTERNAL) && defined(STM32F30X) && defined(CPU_CLK_64_MHZ)) #if STM32F3_64MHZ_INT void STM32F3_64MHz_Internal(void); #endif #define FIRMWARE_VERS "STM32 FOC SDK\0Ver.4.3.0" const char s_fwVer[32] = FIRMWARE_VERS; #ifdef __GNUC__ /* With GCC/RAISONANCE, small printf (option LD Linker->Libraries->Small printf set to 'Yes') calls __io_putchar() */ #define PUTCHAR_PROTOTYPE int __io_putchar(int ch) #else #define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f) #endif /* __GNUC__ */ #if defined(EXAMPLE_SPEEDMONITOR) void speedmonitor_start(void); #endif #if defined(EXAMPLE_POTENTIOMETER) void potentiometer_start(void); #endif #if defined(EXAMPLE_RAMP) void ramp_start(void); #endif #if defined(EXAMPLE_PI) void NewPIval_start(void); #endif #if defined(EXAMPLE_CONTROLMODE) void TqSpeedMode_start(void); #endif /* Private function prototypes -----------------------------------------------*/ void SysTick_Configuration(void); static void ADC_Config(void); static void DMA_Config(void); static uint32_t PA5_ADC; /* Private variables ---------------------------------------------------------*/ CMCI oMCI[MC_NUM]; CMCT oMCT[MC_NUM]; uint32_t wConfig[MC_NUM] = {UI_CONFIG_M1,UI_CONFIG_M2}; /* Private macro -------------------------------------------------------------*/ /* Private variables ---------------------------------------------------------*/ /** * @brief Main program. * @param None * @retval None */ int main(void) { /*!< At this stage the microcontroller clock setting is already configured, this is done through SystemInit() function which is called from startup file (startup_stm32f10x_xx.s) before to branch to application main.
