Comprehensive Official Resources on STM32 IAP
ISP uses communication interfaces for programming, and the boot code is written by the manufacturer and cannot be changed. IAP (In-Application Programming) refers to the ability of an MCU to obtain new code and reprogram itself, allowing a program to change the program. In application programming (IAP), the user’s application code erases/programs the internal Flash … Read more

Official Training Materials for STM32F0 Cortex-M0: 19 Lectures Shared
The Cortex-M0 is part of the M0 series within the Cortex-M family. Its main feature is a low-power design. The Cortex-M0 is a 32-bit, 3-stage pipeline RISC processor, with a core architecture based on the von Neumann structure, meaning that instructions and data share the same bus. As a next-generation processor, the design of the … Read more
Using ADC Measurement: Internal STM32 ADC Pins vs. External ADC7606-like ADC Chips
In embedded system design, selecting an ADC chip requires a comprehensive consideration of performance, application scenarios, and development costs. The STM32’s ADC and dedicated ADC chips like the AD7606 exhibit significant differences in core parameters, functional features, and applicable scenarios. Below is a comparative analysis and selection advice for both: 1. Performance Parameter Comparison 2. … Read more

Microsecond-Level Delay Made Easy! Precise Timing Control Using STM32 Hardware Timers
In embedded development, precise delay control is crucial for many applications, especially in scenarios such as sensor sampling and protocol timing control. Traditional methods of implementing delays often rely on simple for loops; however, this approach not only lacks precision but also wastes a significant amount of CPU resources during long delays. To improve delay … Read more
