STM32-Based Dual-Loop Servo Control System with Encoder Feedback
High-precision motion control demands robust feedback architectures, and the dual-loop servo system stands as a proven solution. By cascading a position control loop (outer) with a velocity loop (inner), this architecture enables precise trajectory tracking while effectively rejecting disturbances and minimizing steady-state error. Unlike singl ...

STM32 Standard Peripheral Library Technical Reference for Basic Peripherals
1. Memory and Bus Architecture
The STM32 architecture is built around a multi-layer bus matrix that facilitates communication between the Cortex-M3 core and various peripherals. Key components include:
I-Code Bus: Fetches instructions from the Flash memory.
D-Code Bus: Accesses data (constants) in Flash or variables in SRAM.
System Bus (S-Bus) ...

Configuring Timer Interrupts on STM32 Microcontrollers
The timer's period is determined by the values in the Auto-Reload Register (ARR) and the Prescaler (PSC). The formula for calculating the interrupt period is as follows:
Timer Period = (ARR + 1) * (PSC + 1) / Timer Clock Frequency
The ARR value sets the maximum count before the counter resets, generating an overflow event and potentially an int ...

Using RViz to Visualize Robot Trajectory on Local Machine
A robot is equipped with an STM32 microcontroller and a Jetson Nano. The STM32 handles motor control and reads data from global positioning sensors, transmitting this information to the Jetson Nano. On the Nano, a node publishes global coordinates, while a subscriber node runs on a local computer to visualize the robot's movement path via RViz. ...

Configuring Interrupt Priority Groups and Preemption on STM32F1 Microcontrollers
Overview of STM32F1 Interrupt Architecture
The STM32F1 series, built on the ARM Cortex-M3 core, supports a significant number of interrupts. While the Cortex-M3 architecture theoretically supports 240 external interrupts, the STM32F103 line simplifies this by implementing 60 maskable interrupts alongside 16 internal exceptions. These interrupts ...
