What is the use of ADCON1 register in PIC 4550?
ADCON1 (A/D control register 1) ADCON2 uses to select voltage reference and selection of port pins for analog inputs. PCFG0: PCFG3 bits in ADCON1 determines which pins of the controller should be configured as analog inputs.
What is significance of ADCON0 and ADCON1 register?
The ADCON0 register, shown in Figure 23-1, controls the operation of the A/D module. The ADCON1 register, shown in Figure 23-2, configures the functions of the port pins. The port pins can be configured as analog inputs (AN3 and AN2 can also be the voltage references) or as dig- ital I/O.
What is ADCON1 used for?
ADCON1 is the register that defines which PORTA pins are used for digital input/output and which are used by the A/D module. As you are only using the port in digital IO mode, set ADCON1 to a value of either 0x06 or 0x07 which makes all the pins digital.
Does PIC microcontroller have ADC?
Most of the PIC Microcontrollers have built in ADC Module. ADC of PIC Microcontrollers have 5 inputs for 28 pin devices and 8 inputs for 40/44 pin devices. It is a 10-bit ADC, ie the conversion of analog signal results in corresponding 10-bit digital number.
Which register is used to setup the ADC clock in PIC microcontroller?
ADCON2 is last a register used to configure ADC of pic microcontroller. This register selects A/D module conversion clock input. In other words, it selects conversion frequency. Furthermore, this register defines the format of 10-bit digital value either as a left-justified or right-justified.
How does ADC work in photos?
ADC of PIC Microcontrollers have 5 inputs for 28 pin devices and 8 inputs for 40/44 pin devices. It is a 10-bit ADC, ie the conversion of analog signal results in corresponding 10-bit digital number. This A/D Converter module can also operate in sleep mode in which clock is derived from its internal RC oscillator.
What is the difference between ADC0804 and MAX1112?
What is the difference between ADC0804 and MAX1112? Explanation: ADC0804 is used for parallel ADC and MAX1112 is used for serial ADC. Explanation: INTR pin tells about the end of the conversion (output) and WR pin tells us to start the conversion (input).
Which compiler is used for PIC controller?
MPLAB XC8 C pic microcontroller Compiler:The MPLAB XC8 C Compiler is the best compiler of top series complier and it only supports the 8 bit pic microcontrollers such as PIC 10, PIC 12 and PIC 18. It is also knowing as ANSI C compiler. It is developed by microchip for program the pic microcontrollers.
What is the function of the adcon1 Register in Pic?
ADCON1 register has two functions. First, all GPIO ports of pic microcontroller have multiple functions. For example, we can use the same port either as a digital pin or analog pin. But we can use only one function at a time. Therefore, we can select pins functionality either as a digital or ADC pin with this register.
What is the ADC module of a PIC microcontroller?
Most of the PIC Microcontrollers have built in ADC Module. Here we are using PIC 16F877A for demonstrating the working. ADC of PIC Microcontrollers have 5 inputs for 28 pin devices and 8 inputs for 40/44 pin devices. It is a 10-bit ADC, ie the conversion of analog signal results in corresponding 10-bit digital number.
How many bits does the adcon0 microcontroller have?
ADCON0 has 8 bits and 2 bits (bit 6-7) have no connection or unused. Firstly, it selects the analog input channel from CH0-CH15 with the help of CHS3: CHS0 bits. We configure these four bits ( from bit 2-5) to select a specific channel.
What are the registers of a PIC microcontroller?
The PIC microcontroller has the registers ADCON0 and ADCON1 that control the conversion. The PIC16F877A has a 10-bit ADC whose results are stored in two registers: ADRESH and ADRESL. The ADCON0 and ADCON1 registers with their corresponding bits are shown:
