STM32ADC_Arduio

The STM32 is a family of microcontroller ICs based on the 32-bit RISC ARM Cortex-M7F, Cortex-M4F, Cortex-M3, Cortex-M0+, and Cortex-M0 cores.[1]STMicroelectronics licenses the ARM Processor IP from ARM Holdings. The ARM core designs have numerous configurable options, and ST chooses the individual configuration to use for each design. ST attaches their own peripherals to the core before converting the design into a silicon die. The following tables summarize the STM32 microcontroller families.

Pins for STM32F103 series

64 Pins

100Pins

144 Pins

STM32F103ZET6 PINS FOR ADC

Second : The ADC for STM32 by Arduino

Step 1: Seek the list about pins ,get your choice of pin for ADC. I get the PA3. 

Step 2: Begin your coding.

       I will list two ways to get the pot’s voltage by ADC.

       The first one’s code: 

The second code:

About the second one , I get the example of Github’s package.

There are six Arduino projects

      Open the file called STM32ADC.c, I find the functions for coding . Using    these API we should make some change ,like the pins .We should find the pins than we choose named PA3 .Don’t care the D23 ,D33 and so on ,you can find the at boards.h ,so just named the pins as usual cause computer knows those .The function you can also know from the notes .

To get the ADC knowledge you can seek them in internet . They will sure you better than me . You’d must know some key words ,like channel ，sample rate … and better to get how ADC work and working process.
