Instructions for Use
Power Supply:
- Ensure the supply voltage (VDD) is within the range of 2.0 V to 3.6 V.
- Connect the VDD pin to a stable power source and the VSS pin to ground.
Clock Configuration:
- Configure the internal high-speed oscillator (HSI) or external high-speed oscillator (HSE) as the system clock.
- Use the System Configuration Tool (STM32CubeMX) to set up the clock tree and generate initialization code.
GPIO Configuration:
- Set the mode (input, output, alternate function) and configuration (pull-up, pull-down, open-drain) for each GPIO pin using the appropriate registers or HAL functions.
Peripheral Initialization:
- Initialize peripherals such as ADC, DAC, timers, and communication interfaces using the HAL library or direct register manipulation.
- Refer to the datasheet and reference manual for specific register settings and configurations.
Interrupt Handling:
- Enable and configure interrupts for the desired peripherals in the NVIC.
- Write interrupt service routines (ISRs) to handle the interrupts.
Low Power Modes:
- Enter low power modes (Sleep, Stop, Standby) by configuring the power control registers.
- Use the appropriate wake-up sources to exit low power modes.
Debugging:
- Connect a debugger (e.g., ST-LINK) to the JTAG/SWD interface for programming and debugging.
- Use an Integrated Development Environment (IDE) like STM32CubeIDE to write and upload code.
Software Libraries:
- Utilize the STM32 HAL (Hardware Abstraction Layer) library for simplified peripheral control.
- Follow the examples and documentation provided in the STM32CubeMX and STM32CubeF1 packages.
Development Tools:
- Use STM32CubeMX to configure the microcontroller and generate initialization code.
- Compile and upload code using an IDE like STM32CubeIDE or Keil uVision.
Documentation:
- Refer to the STM32F101xx datasheet and reference manual for detailed information on registers, timing, and electrical characteristics.
- Consult the STM32CubeF1 package for application notes, user manuals, and example projects.
