RTC can be used for chronometers, alarm clocks, watches, small electronic agendas, and many other devices and today we are going to learn HOW to access internal RTC in STM32.
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.
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.
The advantage of using adc with DMA is that we can use multi channel conversion. The result of the conversion will be stored in the memory…..
