[ACM32G103RCT6 development board review] OLED multi-level menu based on tobudOS [Copy link]

 

[Purpose of the experiment] Implementation of a multi-level menu based on tobudOS

【experiment equipment】

1. ACM32G103RCT6 development board

2. Rotary encoder

3. OLED screen

【Development board software】

1. MDK5.38

2. TobudOS

【Realize step gathering】

1. Copy a tobudOS project template

2. Transplant the OLED display driver. Copy the OLED driver library, create a new project grouped as OLED, and add the .c and .h files to the project.

3. Modify the initialization, write bytes, write commands, and write data of OLED. I use the hardware I2C driver here (the driver is not given in detail, and I wrote a 10,000 OLED driver). I saw this driver on Bilibili and shared it with you.

void I2C_Init(void)
{
    I2C_Handle.Instance           = I2C1;
    I2C_Handle.Init.I2C_Mode      = I2C_MODE_MASTER;
    I2C_Handle.Init.Tx_Auto_En    = TX_AUTO_ENABLE;
    I2C_Handle.Init.Clock_Speed   = CLOCK_SPEED_STANDARD; 
    I2C_Handle.Init.Stretch_Mode  = STRETCH_MODE_DISABLE;   
    I2C_Handle.Init.filter_enable = FILTER_ALGO_DISABLE; 
    
    HAL_I2C_Init(&I2C_Handle);
}

/**
  * 函    数：I2C发送一个字节
  * 参    数：Byte 要发送的一个字节数据，范围：0x00~0xFF
  * 返 回 值：无
  */
void OLED_I2C_SendByte(uint8_t Byte)
{
	uint8_t i;
	HAL_I2C_Master_Transmit(&I2C_Handle, 0x78, &Byte, 1, 100);
}

/**
  * 函    数：OLED写命令
  * 参    数：Command 要写入的命令值，范围：0x00~0xFF
  * 返 回 值：无
  */
void OLED_WriteCommand(uint8_t Command)
{
	int8_t buff[2];
	buff[0] = 0x00;
	buff[1] = Command;
	HAL_I2C_Master_Transmit(&I2C_Handle, 0x78, buff, 2, 100);
}

/**
  * 函    数：OLED写数据
  * 参    数：Data 要写入数据的起始地址
  * 参    数：Count 要写入数据的数量
  * 返 回 值：无
  */
void OLED_WriteData(uint8_t *Data, uint8_t Count)
{
	uint8_t i;
	
	int8_t buff[Count+1];
	buff[0] = 0x40;
	for(i = 1; i<Count; i++)
	{
		buff[i] = Data[i];
	}
	HAL_I2C_Master_Transmit(&I2C_Handle, 0x78, buff, Count+1, 100);
}

4. Key drive. There is a key on the rotary encoder. I connected it to the onboard key PC13. The code is as follows:

int8_t Key_Enter_Get(void)
{
	if(Key_Enter)
	{
		Key_Enter = 0;
		return 1;
	}
	return 0;
}

void HAL_EXTI_LineCallback(uint32_t Line)
{
	if (Line == BSP_PB_PIN)
	{
		BSP_LED_Toggle();
		Key_Enter += 1;
	}
}

5. The encoder driver is described in detail in the post: [ACM32G103RCT6 Development Board Evaluation] TobudOS implements the initial test of multi-task encoder - Domestic chip exchange - Electronic Engineering World Forum (eeworld.com.cn) , so I will not go into details. The code is as follows:

#include "main.h"                  // Device header

TIM_HandleTypeDef TIM15_Handler;  // PA2 and PA3  
/************************************************************************
 * function   : TIM6_IRQHandler
 * Description: TIM6 Interrupt Handler 
 ************************************************************************/ 
void TIM15_IRQHandler(void)
{
	if (TIM15->SR & TIMER_SR_UIF)
	{
		
	}
	
	TIM15->SR = 0;   //write 0 to clear hardware flag  
}

void TIM15_MSP_Pre_Init(TIM_HandleTypeDef * htim)
{
	HAL_TIMER_MSP_Init(&TIM15_Handler);   
}

void TIM15_MSP_Post_Init(void)
{
	GPIO_InitTypeDef gpio_init; 
	__HAL_RCC_GPIOC_CLK_ENABLE();
    
	gpio_init.Pin = GPIO_PIN_1 | GPIO_PIN_2;  //TIM15_CH1 and TIM15_CH2  
	gpio_init.Mode = GPIO_MODE_AF_PP;          
	gpio_init.Pull = GPIO_PULLUP;    
	gpio_init.Alternate = GPIO_FUNCTION_1;    
    gpio_init.Drive = GPIO_DRIVE_LEVEL3;   
	HAL_GPIO_Init(GPIOC, &gpio_init);   	 
}

void TIM15_Init(void)  
{
    uint32_t timer_clock; 
    TIM_SlaveConfigTypeDef sSlaveConfig = {0};   
    
    timer_clock = HAL_RCC_GetPCLK2Freq();  
    
    if (HAL_RCC_GetHCLKFreq() != timer_clock )  // if hclk/pclk != 1, then timer clk = pclk * 2  
    {
       timer_clock =  timer_clock << 1;    
    }
    
	TIM15_Handler.Instance = TIM15;
	TIM15_Handler.Init.ARRPreLoadEn = TIM_ARR_PRELOAD_ENABLE;    
	TIM15_Handler.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; 
	TIM15_Handler.Init.CounterMode = TIM_COUNTERMODE_UP; 
	TIM15_Handler.Init.RepetitionCounter = 0;  
	TIM15_Handler.Init.Prescaler = 0;      
	TIM15_Handler.Init.Period = 0xFFFF;   
	
	TIM15_MSP_Pre_Init(&TIM15_Handler);       
	HAL_TIMER_Base_Init(&TIM15_Handler);    
	HAL_TIM_ENABLE_IT(&TIM15_Handler, TIMER_INT_EN_UPD); 
	TIM15_MSP_Post_Init();  
    
  sSlaveConfig.SlaveMode = TIM_SLAVE_MODE_ENC1;  
	sSlaveConfig.InputTrigger = TIM_TRIGGER_SOURCE_TI1FP1;  
	sSlaveConfig.TriggerPolarity = TIM_SLAVE_CAPTURE_ACTIVE_RISING;         
	sSlaveConfig.TriggerFilter = TIM_TI1_FILTER_LVL(0);  // no filter     
	HAL_TIMER_Slave_Mode_Config(&TIM15_Handler, &sSlaveConfig);   
    
	        
}




int16_t Read_Encoder(void)
{
	int16_t Encoder_TIM;
	Encoder_TIM = (int16_t) TIM15->CNT-65536;
	TIM15->CNT = 65536;
	return Encoder_TIM;
}


void Encoder_Init(void)
{
	TIM15_Init();
	HAL_TIMER_Base_Start(TIM15_Handler.Instance);  
}

int16_t Encoder_Get(void)
{
//	/*原样输出*/
//	int16_t temp;
//	temp = TIM_GetCounter(TIM1);
//	TIM_SetCounter(TIM1, 0);
//	return temp;
	
	/*除以4输出*/
	int16_t temp;
	temp = (TIM15->CNT+2)/2;
	if(temp)
	{
		TIM15->CNT = TIM15->CNT-(temp*2);
		return temp;
	}
	return 0;
}

void Encoder_Reset(void)
{
	TIM15->CNT = 0;
}

5. Migrate the menu. Find the open source code on the Internet and copy the menu to the project.

6. Schedule main_menu in a task to achieve the menu effect.

I learned a lot, thank you sir

Thank you for your attention. Tobudos is still in its early stages and I hope you can pay attention to it.

What operating system is this?

TobudOS is a domestic product donated by Tencent to the open source foundation. It has been out for a long time and has now changed its name.
