Power Supply Setup: Ensure the power supply voltage is within the specified range of 1.7 to 3.6V. Connect VDD and VSS appropriately.
Clock Configuration: Configure the system clock using the internal high-speed RC oscillator, external crystal, or PLL as needed. The maximum frequency is 170 MHz.
Flash Programming: Use a programmer compatible with the STM32 series to load firmware into the flash memory. Ensure programming tools are configured for the correct memory size and address ranges.
Peripheral Initialization: Initialize peripherals like ADC, DAC, timers, and communication interfaces according to your application requirements. Refer to the datasheet for specific initialization routines.
Power Management: Implement low-power modes such as Sleep, Stop, or Standby to optimize power consumption based on the operational needs of your application.
Debugging: Utilize the SWD interface for debugging purposes. Connect to a debugger tool that supports the STM32G4 series.
Capacitive Touch Sensing: For applications requiring touch sensing, configure the capacitive sensing channels through software libraries provided by STMicroelectronics.
Electrostatic Discharge (ESD) Protection: Handle the device with care to avoid ESD damage. Follow proper anti-static protocols during assembly and handling.
Thermal Considerations: Ensure adequate heat dissipation if operating near the upper temperature limit. Check thermal resistance specifications in the datasheet.
For detailed configuration and more specific instructions, refer to the official STM32G474VET6 datasheet and reference manual available from STMicroelectronics.
