WeAct Studio STM32G474CEU6 Core Board Demo Board

You can program this board using STMicroelectronics' STM32CubeIDE or STM32CubeMX with the HAL/LL libraries. It is also compatible with the Arm Keil MDK and IAR Embedded Workbench professional toolchains. For open-source options, you can use PlatformIO with the STM32 platform or Arduino IDE with the STM32duino core, though full peripheral access is best achieved through the official STM32Cube ecosystem.

The board's pins for the five 12-bit DAC outputs and six op-amp inputs/outputs are broken out to the 100-pin header. Consult the STM32G474 reference manual and the board's pinout diagram. Configure the DAC channels and internal op-amp routing using STM32CubeMX's graphical pinout and peripheral configuration tool, which generates initialization code to set up the analog signal chain, including gain settings and buffer modes for the integrated amplifiers.

Yes, the STM32G474CEU6 supports CAN FD (Flexible Data-rate). You need to connect the board's CAN_TX and CAN_RX pins (specific to the chosen CAN instance, e.g., CAN1) to an external CAN FD transceiver chip, such as a TJA1042 or TJA1051. The transceiver then connects to the CAN bus network via its CANH and CANL terminals. Ensure proper termination (120-ohm resistor) at both ends of the bus and configure the baud rates for arbitration and data phases in your firmware.

The board typically operates from a 3.3V supply, which can be provided via a regulated external power source connected to the appropriate pins or a USB connection if the board includes a USB-to-serial bridge with power delivery. Ensure your power supply can deliver sufficient current for the core and all active peripherals. Use decoupling capacitors close to the MCU's power pins as per the STM32G474 datasheet recommendations for optimal noise immunity and stable analog performance.
