ADC conversion Time/Frequency Calculation in STM32
ADC Conversion Time = Sampling Time + 12.5 Cycles. Here Sampling Time is something that you can choose during the setup in the CubeMX.
How to LOG Sensors data into SD card
We will read the data from Potentiometre, which is connected via ADC, also read from DHT11 temperature sensor, and we will write this data to the SD card
DS18B20 and STM32
The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with non-volatile user-programmable upper and lower trigger points.
