FreeRTOS is a real-time operating system (RTOS) for embedded systems. It has been ported to 35 microprocessor architectures. Since 2017, it has been distributed under the MIT license. Prior to 2017, it was distributed under a modified GPL license with an exception allowing the developer to assign mo...

Part 8 of the tutorial deals with UART in LPC2148. In this, we will understand some basics of UART in general and in LPC2148. The Pins associated with UART are explained and also the list of registers used for UART. The next topic will be about baud rate generation in the UART module and calculation...

In the seventh part of the series, we will discuss a new topic called Pulse Width Modulation (PWM). Here, we will see the uses of PWM, types of PWM signals in LPC2148 and also the pins that are capable of generating PWM. We will understand how PWM is generated in LPC2148 and the registers related to...

In this tutorial, we will see the concept of interrupts in microcontrollers and the use of interrupts in embedded systems. Then, we will see how the interrupts are handled in LPC2148 and the registers associated with them. We will also see how to initialize the interrupts and configure interrupts in...

The next part of the ARM7 tutorial series is the concept of Timers in LPC2148. We will discuss some basics of timers and counters in LPC2148 and the registers with respect to Timers in LPC2148. Then, we will see how to configure the Timers as per our needs. Finally, we will once again blink the LEDs...

We will develop a small project in this part of the tutorial involving LPC2148 MCU and LCD display. As LCD is an important component in the world of embedded systems, we will see some basics about LCD modules and the pin configuration of the typical 16 x 2 LCD display. We will then interface the LCD...

Part 3 of the tutorial will be about Phase Locked Loop (PLL) in LPC2148. It gives an introduction to PLL in general, the use of PLL in LPC2148 and types of PLLs. After the basic introduction, the next topic will be understanding different registers that are related to PLL and also setting up the PLL...

This part gives an introduction to the Pin Configuration of the LPC2148 MCU. It acts as a guide to understanding the general purpose input / output (GPIO) pin, different registers associated with the GPIO operations and different ways to initialize the registers. Finally, we will see a real time exa...

The first part of the tutorial is a basic introduction of the ARM Processors, features of ARM processors, explaining the features of the ARM processors, different families of ARM processors and their corresponding architectures, general nomenclature used in ARM processors. It also gives a brief idea...

Dear forum members! All necessary materials and guides for installing Keil, CubeMX, Arduino IDE, and configuring the Izbuschka constructor are available on our forum in the "Guides" (registration required for viewing). In this topic, you can ask questions that arise during your learning p...
