What is Gpio in ARM?
General-purpose input/output (GPIO) is a pin on an IC (Integrated Circuit). It can be either input pin or output pin, whose behaviour can be controlled at the run time. A group of these pins is called a port (Example, Port 0 of LPC2148 has 32 pins).
What is PINSEL0?
PINSEL0 : – PINSEL0 is used to configure PORT0 pins P0.
What is difference between microcontroller and microprocessor?
Brief overview: Microprocessor consists of only a Central Processing Unit, whereas Micro Controller contains a CPU, Memory, I/O all integrated into one chip. The microprocessor is useful in Personal Computers whereas Micro Controller is useful in an embedded system.

How many number of steps are there for ADC in LPC1768?
LPC1768 has an inbuilt 12 bit Successive Approximation ADC which is multiplexed among 8 input pins. The ADC reference voltage is measured across VREFN to VREFP, meaning it can do the conversion within this range.
How do you program ADC?
Steps for Configuring ADC
- Configure the GPIO pin for ADC function using PINSEL register.
- Enable the CLock to ADC module.
- Deselect all the channels and Power on the internal ADC module by setting ADCR.
- Select the Particular channel for A/D conversion by setting the corresponding bits in ADCR.SEL.
- Set the ADCR.
What is Cmsis arm?
CMSIS enables consistent device support and simple software interfaces to the processor and its peripherals, simplifying software reuse, reducing the learning curve for microcontroller developers, and reducing the time to market for new devices.
What does GPIO mean?
General Purpose Input/Output
General Purpose Input/Output (GPIO)
What is GPIO register?
The GPIO provides general-purpose input and output signals that are connected to J20. Each GPIO line has a 10KΩ pullup resistors to 3.3V. The GPIO registers are shown in Table 4.1.
What is difference between GPIO and GPIO?
A GPIO pin is a generic pin whose value consists of one of two voltage settings (high or low) and whose behavior can be programmed through software. A GPIO port is a platform-defined grouping of GPIO pins (often 4 or more pins).
Is GPIO analog or digital?
digital
A general-purpose input/output (GPIO) is an uncommitted digital signal pin on an integrated circuit or electronic circuit board which may be used as an input or output, or both, and is controllable by software.
Is arm a processor or controller?
ARM is the latest technology which replaced by microcontrollers and microprocessors. Basically ARM is a 16 bit/ 32 bit Processors or Controllers. ARM is the heart of advanced digital products like mobile phones automotive systems digital cameras and home networking and wireless technologies.
Are GPIO pins analog or digital?
All 17 of its GPIO pins are digital. They can output high and low levels or read high and low levels. This is great for sensors that provide a digital input to the Pi but not so great if you want to use analogue sensors.
