In the ADC configuration, Enable SCAN CONVERSION and Continuous Conversion, If you don’t know what they are, please go to the links in the first paragraph.
Pulse Width Modulation is one of the important functions of timer. PWM is a technique to control analogue circuits with digital output from microcontroller.
As you all know that an Analogue signal is the one whose value varies continuously with time whereas digital signals can only be either high or low.
LM35 is an integrated-circuit temperature device with an output voltage linearly proportional to the centigrade temperature. As LM35 is not calibrated in Kelvin, user does not require to subtract large constant voltage from the output to obtain convenient centigrade scaling.
So here I am starting I2C tutorial in STM32. I know it’s early because we still need to go through some basic things before jumping to I2C but the problem is LCD. It takes a whole lot of efforts to interface LCD using conventional methods, but by using I2C, we can do it really easy. I will cover other ways to interface LCD later in upcoming tutorials. Before using I2C to interface LCD, let’s first write a simple code to know about I2C functions.
