Since Zhaoyi Innovation Technology has been involved in the microcontroller field, it is quite rapid, recently, and recently launched a new series of high-cost enhanced microcontroller GD32F2 series, with oneself The original technology in the Flash is combined with the Cortex-M3 processor. In addition to the industry's largest flash capacity, the GD32F2 microcontroller has strengthened support for video images, liquid crystal display, storage expansion, and high-speed signal acquisition. The enhanced hardware encryption module and security architecture can be said to provide comprehensive enhanced processing capabilities and new peripheral interface resources based on the previous generation GD32F1 product. At the same time, Zhaoyi innovation also provides a simple and easy-to-use evaluation board for the new series of microcontrollers. Engineers can evaluate the performance and peripherals of GD32F2 series microcontrollers through it. resource.
GD32 Colibri-F207ze Development Board
The pavilion network is fortunate to get the engineering board for the GD32 Colibri-F207ze development board. As shown in the figure below, this is similar to the GD32 Colibri-F150R8 development board that we have touched before, the size is similar to a credit card, it is very Conveniently carrying "Pocket Labs".
It is worth mentioning that the GD32 Colibri-F207ZE card acquired is equipped with a Maguo innovative GD-LINK debugger, which is also equipped with a CH340-based USB to serial handle, making the board directly through the ordinary miniusb. You can get serial port function, which greatly facilitates the development time of engineers in serial debugging, while also saving costs.
Advantageously, the increase in the onboard USB serial port function also makes the design of the GD32 Colibri-F207ZE panel type unlike the GD32 Colibri-F150R8, it can be used by GD-Link, a bit regret.
The GD32 Colibri-F207ZE development board basically still can also be seen as the minimum system board based on the GD32F207Zet6 microcontroller, the onboard resource is clear, as shown in the figure below.
GD32 Colibri-F207ze Main onboard resources:
GD32F207ZET6 microcontroller, based on ARM Cortex-M3 processor, maximum frequency is 120MHz
3 mechanical buttons: a reset button, two user buttons
Two miniusb interfaces: a use in GD-LINK, one for serial communication
Arduino Uno3 expansion interface
The GD32 Colibri-F207ze development board is as simple as possible, mainly including LED, Key, serial port, and also supports more peripherals by compatible with the current ARDUINO UNO3 interface. Of course, if the GD32 Colibri-F207ze development board is the biggest advantage, the onboard GD32F2 series microcontroller product can be compatible with ST and the product of the GD32F1 series on the pin and code, This allows engineers to transplant the code from the previous product to the latest GD32F2 platform.
GD32F207Zet6 microcontroller
In the above, the GD32 Colibri-F207ZE development board main controller is equipped with Zhaoyi innovative GD32F2zet6. In fact, we are not strange to this master, this and love board network evaluation GD32207i-Eval development board The microcontroller (GD32F207ikt6) is partially affiliated with the same series, which is basically consistent, but is only castrated on the storage of the microcontroller. GD32F207zet uses LQFP144 packages, up to 114 IO extensions, is very rich, as shown in the following figure.
GD32F207ZET6 microcontroller characteristics:
Based on ARM Cortex-M3 processor, main frequency 120MHz, integrated 512KB Flash, 128KB SRAM
General Timer * 10, ADV. TM * 2, Basic TM * 2, System Clock * 1, Watch Dog * 2, RTC * 1
USART * 4, UART * 2, I2C * 3, SPI * 3, I2S * 2, SDIO * 1, CAN2.0B * 2, USB2.0 OTG FS * 1, Ethernet Mac * 1
TFT-LCD * 1, Digital camera interface * 1, Crypro / haveh * 1, exmc / sdram * 1
ADC * 3, DAC * 2, up to 114IO expansion
According to the information provided by Zhaoyi official, the GD32F2 series microcontroller is currently 27 products, and maintains the perfect compatibility with GD32's existing products in software and pin packaging, in fact, Zhao Yi's product basics The function is consistent, but it is only increased on the number of Flash, SRAM, and peripheral interfaces.
The GD32F2 series microcontroller also supports Zhaofi-specific patented technology-kernel access flash high-speed zero waiting technology, which allows the processor to access Flash speed to achieve the fastest, no waiting time, greatly enhanced code execution efficiency; At the same time, both the GD32F2 series microcontroller has three power saving modes: sleep mode, deep sleep mode, standby mode, support 2.6V ~ 3.3V power supply, some IO can also withstand 5V level, prevent accidental damage under improper operating conditions chip.
We see the onboard GD32F207zet6 microcontroller belongs to the mid-end configuration in the GD32F2 series, 512KB Flash, 128KB SRAM, LCD interface, digital camera interface, Ethernet MAC interface, USB OTG interface, etc., the function is very rich, The maximum can support 114 IO ports, users can flexibly flexibly DIY, which can be highly flexible through the IO-mouth seat leading to the GD32 Colibri-F207ze development board. Super performance, rich features make GD32F2 series microcontrollers have a very broad application prospect in many applications, such as industrial control, human-machine interaction interface, alarm system, GPS, game and other fields.
