Click the blue text Follow us 1. Overview CAN stands for Controller Area Network, which is an ISO standardized serial communication protocol and one of the most widely used field buses internationally. CAN communication uses only two signal lines, namely CAN_High and CAN_Low. The CAN controller determines the bus level based on the potential difference … Read more
32 Single Chip Microcontroller I O When it comes to the IO of the 32-bit microcontroller, taking the F1 series as an example, we first need to mention: 1 initialization function: void GPIO_Init(GPIO_TypeDef* GPIOx, GPIO_InitTypeDef* GPIO_InitStruct); 2 functions to read input levels: uint8_t GPIO_ReadInputDataBit(GPIO_TypeDef* GPIOx, uint16_t GPIO_Pin); uint16_t GPIO_ReadInputData(GPIO_TypeDef* GPIOx); 2 functions to read output … Read more
This guide covers hardware selection, model optimization, toolchain operations, code implementation, and debugging techniques, using the STM32 series microcontrollers as an example: 1.Hardware Selection and Configuration (1)Clarify Requirements Computational Requirements: Simple classification tasks (e.g., binary classification of sensor data):Cortex-M0+/M3 (e.g., STM32G0/F1) are sufficient. Complex tasks (image recognition, speech processing): Choose models with hardware acceleration (e.g., … Read more
