1. Design Concept For controlling the LED light, we can imagine the functions of the LED light. The first is the switch, brightness, and color, which are the main three functions. How can we abstract these three functions? Regardless of what the underlying LED device is, we can abstract it using this structure. As shown … Read more

Before use, please supply the small board with a sufficiently powered adapter. At this point, the power indicator light on the small board will light up. Insert the small board into the IDC10 interface of the RT809H programmer in the correct direction. The programmer needs to have a programming socket inserted; at this time, the … Read more
The JTAG online read/write board for inverter air conditioners, G-Matrik TMS320F28035, requires the installation of a QFP80 programming seat on the programmer. The RT809H programmer is suitable for this purpose. For online read/write, please enter the following in the software: TMS320F28035 #ISP Be careful not to select the wrong option; for online read/write, choose the … Read more
Following the previous article, we learned about the erase, write, and read functions of FLASH, but there is still a lack of understanding regarding the relationship with JTAG. This article supplements the JTAG part. First, let’s take a look at the hierarchical structure of JTAG programming FLASH, as shown in the figure below: The physical … Read more
Embedded Systems: The “Invisible Heroes” Around Us In today’s digital age, embedded systems are like “behind-the-scenes heroes,” quietly yet omnipresently integrated into our daily lives. When you are gently awakened by a smart alarm clock in the morning, it is the embedded system running in an orderly manner behind its precise timing function; stepping into … Read more
Setting breakpoints is a very effective way to debug programs online. Combined with step-by-step debugging, it can quickly locate problems. However, sometimes manually setting breakpoints is not very convenient. For example, if you want to stop at the Nth iteration of a loop, you would have to keep clicking step run until the loop reaches … Read more
Introduction It is common for users of KEIL to encounter the issue of needing to run part or all of the program code in RAM. This article summarizes several methods to run programs in RAM using an example from the STM32F411 Nucleo. We will start with the ToggleLED function executing in Flash. Below is the … Read more
