okay, let's dive into a detailed tutorial on using the stm32g4 series on-chip loader (olt), watchdog timers (wdg), and high-resolution timer (hrtim), specifically focusing on generating a complex pwm waveform with advanced features. we'll cover the theoretical background, practical considerations, and provide a code example to get you started.

*i. overview of stm32g4's peripheral landscape*

before diving into the individual components, let's understand how they fit together in the stm32g4 ecosystem:

*stm32g4 series:* the stm32g4 is a family of microcontrollers based on the arm cortex-m4 core with fpu. they are known for their high-performance analog peripherals, advanced motor control capabilities, and digital power conversion features. they are well-suited for applications like digital power supplies, motor drives, solar inverters, and high-performance industrial control.

*on-chip loader (olt):* the olt is a built-in bootloader in the stm32g4. it allows you to program the flash memory of the microcontroller through various interfaces like uart, spi, i2c, and usb (dfu – device firmware upgrade). it's the initial programming method, and you usually replace it with your own bootloader later in the development lifecycle.

*watchdog timers (wdg):* watchdog timers are crucial safety features in embedded systems. they are independent timers that, if not "kicked" (reset) periodically by the application code, will trigger a system reset. this is a safeguard against software crashes, deadlocks, or any other unexpected behavior that could compromise the system's operation. the stm32g4 typically has two types of watchdog timers:

*independent watchdog timer (iwdg):* the iwdg runs from its own dedicated low-speed clock (usually lsi - low speed internal). this makes it very robust against issues that might affect the main system clock.
*window watchdog timer (wwdg):* the wwdg allows you to define a "window" of time in which the w ...
