CH32V307V-EVT-R1 Top View

The CH32V307V-EVT-R1 is a development board for the CH32V307 RISC-V MCU. This page contains my initial notes on how to work with this board and the CH32V307 MCU. My initial experiments are also on Github here: https://github.com/lbthomsen/CH32V307V-EVT-R1.

As a development board, this one is clearly inspired by ST's Nucleo boards as it includes an Arduino header as well as a built-in flash/debug tool (they call it WCH-Link also inspired by ST-Link).

I never really understood why they (both this one and ST) choose to include an Arduino header. As far as I know, most - if not all - Arduino boards are running at 5V, which makes them possibly incompatible with the 3.3V used on boards such as this.

The CH32V307V-EVT-R1 board itself is readily availble from LCSC at around $12 (+ shipping).

Hardware Description

It is worth noticing that contrary to various ST development boards, the two user LED's and the user button are by default only wired to the header, not the MCU itself. This means that a jumper lead is necessary to use any of these.

MounRiver Studio

Installing

The MounRiver Studio community edition can be downloaded from http://www.mounriver.com/download (warning, insecure link).

Installing it (on Linux) is really quite simple. Unpack the downloaded archive: 

lth@ncpws04:~$ tar xvf Downloads/MounRiver_Studio_Community_Linux_x64_V110.tar.xz

After the archive has been unpacked a few tweaks are necessary. MounRiver provided a script for this: 

lth@ncpws04:~$ cd MounRiver_Studio_Community_Linux_x64_V110/beforeinstall/
lth@ncpws04:~/MounRiver_Studio_Community_Linux_x64_V110/beforeinstall$ ./start.sh

And that is about it. You can now run MounRiver Studio like this: 

lth@ncpws04:~$ ~/MounRiver_Studio_Community_Linux_x64_V110/MRS_Community/MounRiver\ Studio_Community

Creating first project

Once the MounRiver Studio has been started, a new project can be created:

File - New project.png

In the resulting dialog, first select the appropriate MCU, then give the project a name:

Create project.png

Notice that there is a bug which change the project name once a MCU is selected, so unless you want all your projects to be named after the MCU, do change the name after you select the MCU.

Pressing Ok will generate a source tree, including a main.c in the User directory:

int main(void)
{
	NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
	Delay_Init();
	USART_Printf_Init(115200);
	printf("SystemClk:%d\r\n",SystemCoreClock);

	printf("This is printf example\r\n");

	while(1)
    {

	}
}

As can be seen, the default application will print out a few statements and then do nothing.

By selecting Project/Build Project

Project-Build.png

The project should be successfully build. The Console window will show the result of the build process:

Getting Started

SysTick Timer

Coming from STM32, I like to have a counter running calibrated at ms resolution (HAL_GetTick() on STM32). By default that is not available on the CH32V307 using the provided SDK. Fortunately it is quite easy to implement: 

/*
 * systick.c
 *
 *  Created on: Jun 29, 2022
 *      Author: lth
 */

//#include "ch32v30x.h"
#include "systick.h"

uint32_t uwTick = 0;

/*********************************************************************
 * @fn      SysTick_Handler
 *
 * @brief   This function handles SysTick interrupt.
 *
 * @return  none
 */
__attribute__((interrupt("WCH-Interrupt-fast"))) void SysTick_Handler(void) {
        SysTick->SR=0;
        ++uwTick;
}

/*********************************************************************
 * @fn      Systick_Init
 *
 * @brief   Initializes Systick.
 *
 * @return  none
 */
void Systick_Init(void) {
    /*Configuration interrupt priority*/
    NVIC_InitTypeDef NVIC_InitStructure = {0};
    NVIC_InitStructure.NVIC_IRQChannel = SysTicK_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;//Seeing priority
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;//Response priority
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;//Enable
    NVIC_Init(&NVIC_InitStructure);

    /*Configuration timer*/
        SysTick->CTLR= 0;
    SysTick->SR  = 0;
    SysTick->CNT = 0;
    SysTick->CMP = SystemCoreClock / 1000; //The latter 1000 represents 1000Hz (that is, 1MS to interrupt once)
    SysTick->CTLR= 0xf;
}

*********************************************************************
 * @fn      GetTick
 *
 * @brief   Get current tick in ms resolution
 *
 * @return  Current tick
 */
uint32_t GetTick() {
        return uwTick;
}

Call the Systick_Init() at the beginning of main and GetTick() will return the number of milliseconds since startup (with wraparound after about 1 1/2 month).
