![]() The STM32F103C8 (Blue Pill) & STM32F432KC have a 12-bit ADC which is a successive approximation analog-to-digital converter. The ADC Tutorial down below is a complete introductory guide for this topic and highly recommended. And the flexibility also to make a lot of decisions like sacrificing resolution in exchange for a higher resolution or having the ADC to trigger on an internal timer signal to periodically sample the analog channels, and much more as we’ll see in this tutorial.įor those who like to have a solid introduction in ADC, how it works at the low level, different types of ADCs, ADC errors, equations, and all other details. Therefore, it’s a valuable resource in microcontrollers and different manufacturers provide us (the firmware engineers) with various features so as to make the best use of it. The ADC is one of the most expensive electronic components especially when it does have a high sampling rate and high resolution. The ADC does the counter operation that of a DAC, while an ADC (A/D) converts analog voltage to digital data the DAC (D/A) converts digital numbers to the analog voltage on the output pin. And it performs a process called quantization so as to decide on the voltage level and its binary code that gets pushed in the output register. The ADC samples the analog input whenever you trigger it to start conversion. And let’s get right into it!Īnalog-To-Digital Converters (ADC) PrefaceĪn ADC (Analog-To-Digital) converter is an electronic circuit that takes in an analog voltage as input and converts it into digital data, a value that represents the voltage level in binary code. We’ll get into the functional description for the ADC in STM32 microcontrollers, how it works, and how to configure it and make the best use of it. Starting with an introduction for the ADC as a digital circuit and then shifting the attention to the STM32 ADC hardware and its features. In this tutorial, we’ll discuss the STM32 ADC (Analog-To-Digital Converter) module.
