[Copy link]
About this activity
On August 22, 2019, GigaDevice announced that it was the first in the industry to introduce the open source instruction set architecture RISC-V into the field of general-purpose microcontrollers, and officially launched the world's first GD32V series 32-bit general-purpose MCU products based on the RISC-V core, providing complete tool chain support from chip negotiation to program code library, development kits, design solutions, and continuing to build a RISC-V development ecosystem.
The release of GD RISC-V has attracted great attention from people from all walks of life. Everyone is curious about the specific performance of this MCU. Our EEWorld forum has also followed up on this matter. This time, we have provided you with two boards for evaluation: the GD32VF103C-START entry-level development board and the GD32VF103V-EVAL full-function evaluation board.
The time requirement for the evaluation report of this evaluation activity is relatively tight. Please correctly estimate your time arrangement, arrange the evaluation plan and choose the evaluation development board reasonably.

5. Announcement of the List
The evaluation list will be announced on the event page and the forum awards area;
6. Evaluation Notice:
After the list is announced, the staff will notify the successful applicants by forum short message and email, and no reply within 3 days will be considered as giving up;
VII. Product delivery:
After the evaluation list is announced, the products will be delivered to everyone as soon as possible. They will be mailed to the address filled in by the applicants when submitting the form. Please make sure that the information is correct and can be received normally when filling in the form;
8. Evaluation Report:
The evaluation will start after receiving the product. Please submit the evaluation report in time according to the evaluation plan submitted by yourself. Please post the evaluation report in the EEWorld forum [GD32MCU] section with the title "GD32VF103C-START Evaluation" + subtitle. The report must be 100% original, and plagiarism will be banned;
IX. Awards
After the experience, you will be scored based on four aspects: timeliness (10%) + article quality (50%) + plan completion (30%) + interaction (10%). If you score well (80 points), you will get the tested development board.
10. Notes:
1. Applicants for the assessment must be EEWorld members with a level of One Grain of Gold Sand (Intermediate) or above.
2. All content shared by the reviewer must be original and first published on EEWorld. If you need to forward it on other sites after the review activity, please indicate the source as EEWorld and attach a link;
3. If the evaluation cannot be completed due to unexpected circumstances, please return the board to EEWorld so that other users can continue the evaluation;
4. If there is no updated content within 15 days of receiving the board, please return the board to EEWorld so that other netizens can continue to review it;
5. If any express delivery fee is incurred during the activity, please pay for it yourself;
6. During the activity, the ownership of the board belongs to EEWorld, and the evaluator only has the right to use the board. The evaluation board is a precision electronic product, so please take good care of it and avoid unnecessary damage. If the board is maliciously damaged during use, the evaluator must compensate according to the price.
7. EEWorld reserves the right to interpret this activity.
GD32VF103 Series RISC-V MCU
The GD32VF103 series RISC-V MCU provides a 108MHz operating frequency, 16KB to 128KB on-chip flash memory and 6KB to 32KB SRAM cache. The patented gFlash technology supports the core to access the flash memory at high speed with zero wait. The Bumblebee core also has built-in single-cycle hardware multipliers, hardware dividers and acceleration units to cope with the challenges of advanced computing and data processing.
The chip is powered by 2.6V-3.6V, and the I/O port can withstand 5V level. It is equipped with a 16-bit advanced timer that supports three-phase PWM complementary output and Hall acquisition interface for vector control, and also has up to 4 16-bit general timers, 2 16-bit basic timers and 2 multi-channel DMA controllers. The newly designed interrupt controller (ECLIC) provides up to 68 external interrupts and can nest 16 programmable priorities to enhance the real-time performance of high-performance control.
A variety of peripheral resources are equipped for a wide range of mainstream applications, including up to 3 USARTs, 2 UARTs, 3 SPIs, 2 I2Cs, 2 I2Ss, 2 CAN2.0Bs, and 1 USB 2.0 FS OTG, as well as an external bus expansion controller (EXMC). Among them, the newly designed I2C interface supports the Fast Plus (Fm+) mode, with a frequency of up to 1 MHz (1Mbit/s), which is twice the speed of the past. The SPI interface also supports four-wire system and adds multiple transmission modes, and can also easily expand Quad SPI NOR Flash for high-speed access. The built-in USB 2.0 FSOTG interface can provide multiple modes such as Device, HOST, OTG, etc. The external bus expansion controller (EXMC) makes it easier to connect external memories such as NOR Flash and SRAM.
The new product integrates two 12-bit high-speed ADCs with a sampling rate of up to 2.6M SPS, provides up to 16 multiplexed channels, supports 16-bit hardware oversampling filtering and configurable resolution, and has two 12-bit DACs. Up to 80% of the GPIOs have a variety of optional functions and support port remapping, continuing to meet the needs of mainstream development applications with flexible and rich connectivity.
