Analog-to-digital conversion is the primary means by which analog signals are converted into digital data that can be processed by. In the real world, most of the signals sensed and processed by humans are analog signals. Before down voting this question, I request, please take some time to tell me why you have down voted, so I can improve my question. An analog-to-digital converter, or simply ADC, is a module that is used to convert an analog signal into a digital code. You can use a simple MCP3008 analog to digital converter (ADC) to read up to 8 channels of. If func_val() is executed and thenĮvalProx(), is the value of proxval influenced by the val? (when both the values depend on ADCRH and ADCRL) By connecting a small analog to digital converter (ADC) chip to the Pi you can open up the world of analog signals to your Raspberry Pi programs This guide will show you a couple great options for reading analog values from Python with a Raspberry Pi. So does the value of proxval influence the value of val when accessed? i.e. Question: The ADCRL/ ADCRH are same for the two different setting of the ADCSC i.e. My question is about the concept of Analog to Digital Converters in MCU.ĪDCRL and ADCRH are the registers in which the converted values are stored.ĪDCSC is the status control register in which I have specified two different channels to be used. Now both the samples are snippets from a bigger code, which compiles and works. While(!ADCSC1_COCO) //check for conversion complete flag.ĪDCSC1 = 0x02 // sets the required channel. Please consider the following codes: //Code Sample 1ĪDCSC1 = 0x00 // sets the required channel.
