Purpose: STM32 learning to use internal DAC Hardware resources: 1, DS0 (connected PA8) 2, 1 serial port (baud rate: 9600, PA9/PA10 connected to the onboard USB to serial chip CH340 above) 3, ALIENTEK 2.8/3.5/4.3/7 inch TFTLCD module (via the GPIO driver, see the connection between lcd.h) 4, button KEY0 (PC5)/KEY_UP (PA0, also known WK_UP) 5, DAC (STM32 internal DAC channels 1 through PA4 output) 6, ADC (STM32 internal ADC1_CH1, connected PA1). Experimental phenomena: In this study, the key (KEY0/KEY_UP two buttons, or USMART) control channel STM32F1 internal DAC module 1 to the output voltage by the ADC1 Channel 1 of the DAC output voltage acquisition, display ADC acquired voltage value and the set value of the DAC output voltage is above the LCD module and other information. And can pass Over usmart call Dac1_Set_Vol function to directly set the DAC output voltage.
