Peripheral Driver Implementation for ARM Cortex-M4 Using HAL Library

Peripheral Driver Implementation for ARM Cortex-M4 Using HAL Library

1. Memory Mapping In the memory mapping diagram of the STM32F429 chip, it can be seen that the peripherals are allocated 512M of space; however, the actual peripherals do not utilize the entire 512M of memory. When operating peripherals, it is sufficient to manipulate their corresponding memory addresses. For more detailed peripheral memory addresses, refer … Read more
