Qt Company recently announced a new toolkit: Qt for MCU. Qt for MCU can run on devices without an operating system, allowing developers to create smooth user interfaces on cost-effective microcontrollers. Qt-based applications can now be deployed on traditional operating systems and microcontrollers based on ARM Cortex M7. How is Qt for MCU implemented? The … Read more

1. Introduction Currently, most microcontrollers come with built-in AD converters that are typically between 10 to 12 bits. In general applications, how much does the bit depth of AD conversion affect measurement errors? Is a 12-bit ADC sufficient? We will discuss the impact of AD conversion bit depth on measurement error through practical measurements. 2. … Read more

To avoid missing my updates, remember to check the public account in the upper right corner and set it as a star, take a star and give it to me. Have you noticed that most microcontrollers operate at 3.3V instead of 3V or 3.5V? Why is that? If you know the reason, please tell us … Read more
To master the STM32 microcontroller, one cannot do without serial communication. Serial communication uses a protocol called the serial communication protocol to manage data transmission, which controls the data flow during transmission, including data bits, baud rate, parity bits, and stop bits. Due to its simplicity and ease of use, serial communication is widely applied … Read more
