用STM32进行4通道ADC转换,采用DMA方式。基准源为2500mv,12位AD采样, 采样电压使用范围为120-750mv,...
模拟采样数据,采样数据中包含3种频率正弦波:50Hz,2500Hz,2550Hz, lBUFIN数组中,每个单元数据高字(高16位)中存储采样数据的实部,低字(低16位)存储采样数据的虚部(总是为0)。 其中dsp_asm_init()函数的作用是产生采样信号,实际工程应用中我们使用的是ADC采样的处理值。dsp_asm_test()函数的作用是进行FFT变换,...

On 64-pin packages and packages with less pins The VREF+and VREF-pins are not available, they are internally connected to the ADC voltage supply (VDDA) and ground (VSSA). 4.1.2 Battery backup domain To retain the content of the Backup registers and supply the RTC function when VDD is ...
In applications, this consumption occurs only while the ADC is on (ADON bit is set in the ADC_CR2 register). 3. External clock is 8 MHz and PLL is on when fHCLK > 8 MHz. Table 19. Typical current consumption in Sleep mode, code running from Flash or RAM Typ(1) Symbol Parameter ...
