Import JSON file in TypeScript

In this example, I will show you a simple way to import JSON files in TypeScript code. It requires just two simple steps. The first is to change the tsconfig.json file by adding the line: , "resolveJsonModule": true in "compilerOptions" section. { "compilerOptions": { ... , "resolveJsonModule": true ... } ... } After that, you have

An Introduction to USB Communication (Part 2)

In this article, we will introduce the USB protocol layer. Please see our previous article for information regarding the physical layer and network topology: An Introduction to USB Communication (Part 1). USB is a polled bus where the host initiates all transactions. For the host to receive information from USB devices, it must request it

An Introduction to USB Communication (Part 1)

USB (Universal Serial Bus) is an industry-standard used to specify cables, connectors, and protocols that are used for communication between electronic devices. Advantages: Self-configuring interface, no need for user configuration of speed, data protocol, etc.Capable of supplying power to small auxiliary devicesVarious communication speeds are supportedStandard connectorsError checking increases the communication reliability Limitations: Limited cable

FreeRTOS: Using MCU Peripheral Drivers

Communication interfaces (I2C, SPI, UART, etc.) are some of the most commonly used microcontroller peripherals in embedded systems. In this introductory article, we will look at how low-level drivers for such peripherals can be used in FreeRTOS. Polled Drivers vs Interrupt-driven Drivers Based on the method used for getting information on events (e.g errors, operation

FreeRTOS: Using Software Timers

In this article, we will take a look at the software timers in FreeRTOS. A software timer allows a function to be executed at a set time in the future.FreeRTOS - RTOS software timer functionality and features description The function that is executed is referred to as a timer's callback function. The interval between starting

Toolset for Debugging Embedded Programs

Writing programs that just work would make the development of embedded systems a lot easier. In practice, however, a considerable amount of time is devoted to finding and removing bugs from the code. This process is commonly known as debugging and there is no way of avoiding it. In this article, we will give an

FreeRTOS: LED Blinking And Button Polling

FreeRTOS is one of the most widely used open-source real-time operating systems (RTOS). In this article, we will look at a very simple FreeRTOS program: a push-button will enable/disable the blinking of an LED. The program is developed and tested using the LPCXpresso54102 board with NXP's LPC54102 microcontroller. The program can be easily adapted for

Using Callbacks in Firmware Development

In its classic form, a callback (aka callback function) is a function that is passed as an argument to another function. The function that accepts the callback as an argument is expected to call back on it (execute it) at a certain point in time. The callback mechanism allows a lower-level software layer to call

Bubble Sort Algorithm

Bubble sort is a simple comparison-based sorting algorithm. It is named like that because it sorts elements similar to the water bubble rising to the surface, i.e. after all iterations are completed, either lower or higher values bubble up towards the top index of the given array. By making multiple passes through an array with
