1. Development Experience The BSP engineers from device manufacturers mainly focus on root filesystem/driver porting/system integration/hardware debugging. It is important to note the distinction from the driver engineers at chip manufacturers. After graduation, the opportunities to write drivers from scratch are few and far between; most of the time, drivers are provided by the chip … Read more
Today, we will learn what a BSP engineer is. Embedded Systems To understand what an embedded software engineer is, we first need to discuss embedded systems (embedded devices). According to Wikipedia, an embedded system is defined as follows: An embedded system is a computer system that is embedded within a mechanical or electrical system, designed … Read more

However, due to the lack of public source … Read more
1 BSP Design Example (Taking STM32 Hardware Platform as an Example) 2 Summary of Hardware Abstraction Layer Design 2.1 Key Points in Module Header File Design 1. Only include definitions of data types and descriptions of interface functions provided for external calls. 2. Generally, do not define variables or describe hardware-related resources, nor include any … Read more
1 Introduction The Hardware Abstraction Layer (HAL) is an interface layer located between the operating system kernel and the hardware circuitry, aimed at abstracting the hardware. It hides the hardware interface details specific to a platform, providing a virtual hardware platform for the operating system, making it hardware-independent and portable across various platforms. The HAL … Read more
During the National Day holiday, NVIDIA published an article on its developer blog: This means that starting from CUDA 11.8, developers can install new versions of the CUDA development package on Jetson just like on PCs! This is indeed a good thing. Why do I say that? Originally, there were two types of systems on … Read more
DNA methylation is one of the earliest discovered forms of gene epigenetic modification. In eukaryotes, methylation occurs only at cytosine, where DNA methyltransferases (DNMTs) convert the 5′ end cytosine of CpG dinucleotides to 5′-methylcytosine. Numerous studies have shown that DNA methylation can induce changes in chromatin structure, DNA conformation, DNA stability, and the interaction patterns … Read more
UNC: Unified Coarse Thread 5/16: Nominal size of the thread, in inches 18: Pitch of 1/18, meaning 18 threads per inch 3A: Tolerance grade, level 3, external thread (B is for internal thread) R.H: Right-hand What Are the Differences Between Metric Threads and Imperial Threads? Metric threads are represented by pitch, while American and British … Read more
Recently, RT-Thread engineers completed the BSP adaptation based on the Renesas CPK-RA2L1 development board, supporting drivers for peripherals such as GPIO, UART, I2C, SPI, ADC, DAC, PWM, CAN, on-chip Flash, Watchdog, RTC, etc. With the support of Renesas engineers, the power component (low power LPM) adaptation was completed. Actual measurements show that the chip can … Read more
In a previous article, we discussed the prediction of CpG islands. Once a CpG island is identified, it is necessary to detect the methylation status of the corresponding region. There are various methods to detect methylation status, but the currently recognized gold standard is the bisulfite sequencing PCR (BSP). BSP Principle Genomic DNA is treated … Read more
