What are the 7 steps to be followed when setting up the PIC16F877A ADC?

In summary, here are the steps to be followed when setting up the PIC16F877A ADC:

  1. Configure the A/D module:
  2. Configure A/D interrupt (if desired):
  3. Wait the required acquisition time.
  4. Start conversion:
  5. Wait for A/D conversion to complete by either:
  6. Read A/D Result register pair (ADRESH:ADRESL), clear bit ADIF if required.

How do you program ADC in PIC16F877A?

How do I use ADC in Mplab?

To read an ADC value the following steps has to be followed.

  1. Initialize the ADC Module.
  2. Select the analog channel.
  3. Start ADC by making Go/Done bit high.
  4. Wait for the Go/DONE bit to get low.
  5. Get the ADC result from ADRESH and ADRESL register.

Which code is used for ADC?

Sampling and quantization are important concepts because they establish the performance limits of an ideal ADC. In an ideal ADC, the code transitions are exactly 1 least significant bit ( LSB ) apart. So, for an N-bit ADC, there are 2N codes and 1 LSB = FS/2N, where FS is the full-scale analog input voltage.

How many pin is PIC16F877A?

It has a total number of 40 pins and there are 33 pins for input and output. PIC16F877A is used in many pic microcontroller projects.

How do I generate PWM with PIC16F877A?

Steps to Configure PWM

  1. Configure the CCP1 module for PWM operation.
  2. Set the PWM period by writing to the PR2 register.
  3. Set the PWM duty cycle by writing to the CCPR1L register and CCP1CON<5:4> bits.
  4. Make the CCP1 pin an output by clearing the TRISC<2> bit.

How many ADC channels are available in PIC16F877A?

It is a 10 bit ADC module. ADC module of the PIC16F877A controller has a 10-bit resolution output. That means an analog input converted into a corresponding 10-bit digital output and 7 channel ADC.

How do I use MCC code configurator?

Just follow the simple steps below to see all the available plug-ins and install MPLAB Code Configurator (MCC).

  1. Select the “Tools” menu and click on “Plugins”
  2. In the MPLAB X IDE Plugins window, click the “Available Plugins” tab.
  3. Select MPLAB Code Configurator and click “Install”

How is ADC calculated in microcontroller?

The ADC reports a ratiometric value. This means that the ADC assumes 5V is 1023 and anything less than 5V will be a ratio between 5V and 1023. If your system is 3.3V, you simply change 5V out with 3.3V in the equation. If your system is 3.3V and your ADC is reporting 512, what is the voltage measured?

What do I need to program a pic18f4550?

All you need is a Microcontroller, An IDE and a Microcontroller programmer Like pickit2 or JDM. For our hardware C programming tutorial we are going to use a PIC18F4550 microcontroller. PIC18F4550 is a 40 pin microcontroller by microchip and it has been a favorite microcontroller in between microcontroller hobbyist.

How PIC18F ADC works?

How PIC18F ADC Works? What is Resolution? How to increase Resolution? Firstly, all PIC18F series has a built-in 10-bit ADC module. Each microcontroller can accept up to 16 analog inputs. In other words, it can have up to sixteen ADC channels. But the actual number of channels depends on the microcontroller, you are using.

What are the features of PIC18F452?

Pic18f452 microcontroller based projects features a ā€˜Cā€™ compiler friendly development environment, 256 bytes of EEPROM, Self-programming, an ICD, 2 capture/compare/PWM functions, 8 channels of 10-bit Analog-to-Digital (A/D) converter,

How many channels can a PIC18F microcontroller accept?

Each microcontroller can accept up to 16 analog inputs. In other words, it can have up to sixteen ADC channels. But the actual number of channels depends on the microcontroller, you are using. However, control and configurations registers are the same for every PIC18F series microcontrollers.
