The Star School (GD) development board is a GD32 development board launched by Flagpoint Technology. The onboard GD32F303ZET6 chip can directly replace the STM32 F103 and GD32F103 series.
Support RT-Thread operating system, etc., support WiFi, 4G, loRa and other IoT communication interfaces. Onboard Flash, eeprom, etc., support 3.2-inch TFT-LCD screen. All IO ports are exported, which can be used for complete peripheral development, including: JTAG, RTC, I2C, UART, SPI, SDIO, EXMC, DAC, ADC, USB, TFT-LCD, etc.
2. Introduction of GD32F303 chip:
The GD32F303 pin is pin to pin with STM32F103 and GD32F303, which can directly replace the chip and upgrade product performance.
GD32F303 has ultra-high computing performance, the highest processor frequency can reach 120MHz, and provides a complete DSP instruction set, parallel computing capability and dedicated floating-point unit (FPU) to meet advanced computing needs. Directly execute code in flash memory at high speed and zero wait, the code execution efficiency at the same main frequency is 10%-20% higher than that of similar Cortex-M4 products in the market, and has completely surpassed Cortex-M3 products, with a performance improvement of more than 40%.
The GD32F303 series integrates a wealth of innovative peripheral resources on-chip, including:
· Cortex®-M4 core @ 120 MHz
·Support software and hardware DSP instructions
· Zero wait state for flash memory access
Built-in 256 KB to 3072 KB flash memory
·Built-in 48KB to 96KB SRAM
·EXMC interface supports external SDRAM
·Up to 5 UARTs (9Mbit/s)
·Up to 3 SPI (30Mbit/s)
·Up to 2 I2C (400Kbit/s)
·Up to 2 CAN2.0B
· Up to 2 I2S
·Support SDIO, Ethernet MAC
·Support USB OTG FS
· Up to three 12-bit, 2.6M SPS ADCs (up to 24 channels)
· Up to 2 DACs
·Standby current is 2uA
3. Performance improvement:
It can be seen that GD32F303 is ahead of STM32F103 and GD32F103 in various performances. At the same time, the pins of GD32F303, STM32F103 and GD32F103 are pin to pin, which can be directly replaced.
