Interfacing of ADC With STM32F1 (ARM CORTEX) Microcontroller

Analog-to-digital converter (ADC)

is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal.

The STM32F103xx medium-density performance line family incorporates the high-performance ARM Cortex-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 20 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer two 12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, an USB and a CAN.
