How to Start Programming for ARM7 Based LPC2148 Microcontroller

This article is about how to start programming for LPC micro-controller. Part and Inventory Search.

Writing 1s produces highs at the corresponding port pins. Writing 1s produces lows at the corresponding port pins.

Distorted Sine output from Programjing 8. Ports are named as P0 and P1. Hierarchical block is unconnected 3. PV charger battery circuit 4. Each pin can perform alternate functions also.


Once the use of above all registers is perfectly understood, you are good to go with programming. How reliable is it? Can u pls help me qrm7.

Configuring GPIO to use different function is out of the scope of this tutorial. The current state of the GPIO configured port pins can always be read from this register, regardless of pin direction.


Group all Htabs ARM. Dear Umesh Thanks a lot. Program to demonstrate the LED blinking. Please don’t make requests for help in programminy using PM.

Dear Umesh sir, This is Balaji, I am doing my project on gas detection. Register Username Email Yes, add me to your mailing list. How do you get an MCU design to market quickly? As mentioned earlier every pin has a max of four functions.

led interfacing with ARM7 ( LPC2148 )

As there can be up to 4 functions associated with lpc218 GPIO pin, two bits for each pin are available to select the function. Each pin can have multiple functions. Port 0 has 32 pins P0.


Here is the pin diagram of LPC Every GPIO pin has a minimum of one function and max of four functions.

LPC Led Blinking – Tutorials

Dec 248: Just keep in mind that by default: All the readers are supposed to write this program in specific software. Input port and input output port declaration in top module 2.

Virgin Galactic — Commercial Space Flight. The below sample code shows how to use the GPIO functions. Writing to this register lpc214 corresponding values in all bits of the particular PORT pins.

This is the GPIO direction control register.
