By Aaron Bauch, Senior Field Application Engineer, IAR Systems Design specifications require the ability to update a device’s firmware in the field dynamically. This is done commonly via a bootloader. Designing a bootloader, however, is challenging as it must meet various requirements. For example, the mechanism for getting the new application into the MPU is…

Setting up the Environment for the development of ARM cortex M3 is well discussed in this article.

A pair of new demos running GeForce RTX technologies on the Arm platform recently unveiled by NVIDIA show how advanced graphics can be extended to a broader, more power-efficient set of devices. The two demos, shown at the recent Game Developers Conference, included Wolfenstein: Youngblood from Bethesda Softworks and MachineGames, as well as The Bistro from the Open…

This project is extension to the previous tutorial which explains how to interface the SD card with an LPC1768. Here we will program to log the temperature reading from a LM35 sensor to a text file periodically. The ARM Cortex M3 runs on 3.3V power supply with a built in crystal frequency of 16 MHz. A 32GB SDSC card from Transcend is used in this particular project, but the code will work with most of the SD cards. The SD card is formatted with FAT32. The ultimate aim of this project is to create a file in the FAT32 file system of the SD card. For setting up the Environment for the development of ARM cortex M3 is well discussed in this article.Insert an SD card into the card holder and upload the sketch to your LPC1768. If the sketch is able to write to the SD card OK, it will create a text file called ‘Temperature.txt.

This project demonstrates the operation and interfacing of a servo motor, where the control signals for the rotation of the motor are provided by LPC1768 (ARM Cortex M3). The servo arm rotation is controlled by a potentiometer interfaced to the ADC of LPC1768. Starting from 0° as initial position it rotates to 180° as the potentiometer rotated from one position to other. For ADC interfacing with LPC1768 refer this article. For basic concepts and know-how of a servo motor, refer to the article Servo Motor. For setting up the Environment for the development of ARM cortex M3 is well discussed in this article.
