According to a report from Electronic Enthusiasts (by Li Ningyuan), in the current motion control field, bus technology and drive technology complement each other. In traditional motion control systems, the control methods are relatively singular. Generally, pulse or analog signals are used as control signals, which are sent to the motor driver, and then the … Read more
The kernel time of Zephyr is driven by sys_clock_announce. Regardless of the SOC type, the system timer is driven by interfacing with this API. For details, refer to the Zephyr Tick Clock Introduction. All system timer drivers for Zephyr are located under zephyr/drivers/timer. How Zephyr Chooses Which Driver to Use All system timer drivers supported … Read more
The startup of the ECU definitely begins with the chip’s BootROM. I have previously written about the startup process of the Infineon Tricore series (if interested, click back to —>What Does Infineon TC27X Need to Do to Start). After the main chip kernel is initialized, what needs to be done for software initialization? In today’s … Read more

Follow+Star Public Number, don’t miss wonderful content Author | strongerHuang WeChat Public Account | Embedded Column Although Keil is often criticized, especially for its interface that feels like it’s from the last century (actually, IAR is similar), but its debugging features should be above reproach, especially for debugging Cortex-M core microcontrollers. Keil MDK supports a … Read more
1. Introduction This is a module for signal acquisition and computation built a couple of days ago using the H7B0 microcontroller, which uses its 16-bit ADC to capture signals and perform spectrum analysis, with results displayed on an OLED screen. Calculating a 2048-point FFT takes about 10 milliseconds. Next, let’s test if the computation speed … Read more
