Embedded Programming in ALGOL: Hardware Interfaces and Real-Time Systems Introduction ALGOL (Algorithmic Language) is a historic programming language that, although less popular today compared to languages like C and Python, played a significant role in the development of computer science. This article will introduce how to use ALGOL for embedded programming, particularly in the application … Read more
Author | strongerHuang WeChat Official Account | Embedded Column Generally speaking, programming on microcontrollers is done in either assembly or C language, and it is rare to use C++ for development. So, can we really use C++ for microcontroller development? The answer is definitely yes! Below, I will discuss some content about writing a LED … Read more
Basic Concepts of Program Design 1、int i=1; void main(){ inti=i; //i is an undefined value } 2、Type Conversion C++ defines a set of standard conversions between built-in type objects: If one operand’s type is long double, the other operand will be converted to long double If neither is long double, if one is double, the … Read more
Introduction Today, we will not cover the Zigbee protocol, but rather some operations of the timer in the CC2530 microcontroller. This article uses 8-bit Timer 3 for experimentation, and other timers can be similarly applied. Through this article: You will learn some basic knowledge about timers. You will see configuration instructions for some timer registers. … Read more
Regarding the idea of layered design, a detailed design process was explained in a previous article titled “Embedded Hardware Communication Interface Protocol-SPI (Part 2) Layered Architecture Design Simulation Interface” when discussing SPI interface design, so I won’t elaborate further here. Now, using the BSP layer design approach of SPI as a reference, we will use … Read more
Implementing a DAC0832 to Output a Sawtooth Wave – Understanding Digital to Analog Conversion from Scratch Today we will implement an interesting case: using the DAC0832 to output a sawtooth wave. Through this case, not only will we learn the basic principles of DACs, but we will also master the methods for waveform generation. Introduction … Read more
