Instructions for Use
Power Supply:
- Ensure the supply voltage is within the operating range of 1.65 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 or external clock source as per application requirements.
- Use the System Configuration (SYSCFG) and Clock Control (RCC) registers to set up the clock tree.
Reset and Boot:
- The device can be reset using the NRST pin.
- After reset, the device starts executing code from the bootloader or user flash memory based on boot configuration.
Peripheral Setup:
- Initialize required peripherals using the appropriate initialization functions provided in the HAL or Standard Peripheral Libraries.
- Refer to the Reference Manual for detailed register configurations.
Power Management:
- Utilize low-power modes such as Sleep, Stop, and Standby to minimize power consumption.
- Manage transitions between these modes using the Power Control (PWR) peripheral.
Debugging:
- Use SWD (Serial Wire Debug) interface for debugging via the PA13 (SWDIO) and PA14 (SWCLK) pins.
- JTAG interface is also available but shares pins with other functions.
Programming:
- Program the flash memory using an ST-LINK programmer/debugger or other compatible tools.
- Follow the programming guidelines specified in the Programming Manual.
For detailed information, refer to the STM32L100R8T6 datasheet and reference manual available on the STMicroelectronics website.
