STM32F103RET7 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the STM32F103RET7 is 72 MHz, but it can be overclocked to 90 MHz with some limitations.
  • The clock settings can be configured using the Clock Control Register (RCC) and the Power Control Register (PWR). The RCC_CR register is used to select the clock source, and the RCC_CFGR register is used to configure the clock prescalers.
  • The BOOT0 and BOOT1 pins are used to select the boot mode of the microcontroller. BOOT0 is used to select between the internal flash and the system memory, while BOOT1 is used to select between the internal flash and an external memory.
  • The USART peripheral can be used for serial communication. To use it, you need to configure the USART_CR1 register to enable the USART, set the baud rate using the USART_BRR register, and configure the USART_CR2 register to select the word length and stop bits.
  • The NVIC is used to handle interrupts generated by the peripherals. It allows you to prioritize interrupts and handle them efficiently. You need to configure the NVIC_ISERx registers to enable interrupts and the NVIC_IPRx registers to set the interrupt priority.
