stm32hal库 控制tm1652

要控制TM1652，需要使用STM32HAL库中的GPIO和SPI模块。首先需要初始化SPI模块，然后通过SPI发送数据给TM1652，控制其显示。

以下是控制TM1652的示例代码：

#include "stm32f4xx_hal.h"

#define TM1652_CS_Pin GPIO_PIN_0
#define TM1652_CS_GPIO_Port GPIOA
#define TM1652_DIN_Pin GPIO_PIN_7
#define TM1652_DIN_GPIO_Port GPIOB
#define TM1652_CLK_Pin GPIO_PIN_6
#define TM1652_CLK_GPIO_Port GPIOB

SPI_HandleTypeDef hspi1;

void TM1652_Init(void)
{
  // 初始化SPI模块
  hspi1.Instance = SPI1;
  hspi1.Init.Mode = SPI_MODE_MASTER;
  hspi1.Init.Direction = SPI_DIRECTION_2LINES;
  hspi1.Init.DataSize = SPI_DATASIZE_8BIT;
  hspi1.Init.CLKPolarity = SPI_POLARITY_LOW;
  hspi1.Init.CLKPhase = SPI_PHASE_1EDGE;
  hspi1.Init.NSS = SPI_NSS_SOFT;
  hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_256;
  hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;
  hspi1.Init.TIMode = SPI_TIMODE_DISABLE;
  hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
  hspi1.Init.CRCPolynomial = 10;
  HAL_SPI_Init(&hspi1);

  // 初始化TM1652
  HAL_GPIO_WritePin(TM1652_CS_GPIO_Port, TM1652_CS_Pin, GPIO_PIN_SET);
  HAL_GPIO_WritePin(TM1652_DIN_GPIO_Port, TM1652_DIN_Pin, GPIO_PIN_SET);
  HAL_GPIO_WritePin(TM1652_CLK_GPIO_Port, TM1652_CLK_Pin, GPIO_PIN_SET);
}

void TM1652_Write(uint8_t addr, uint8_t data)
{
  uint8_t tx_data[2];
  tx_data[0] = addr;
  tx_data[1] = data;

  HAL_GPIO_WritePin(TM1652_CS_GPIO_Port, TM1652_CS_Pin, GPIO_PIN_RESET);
  HAL_SPI_Transmit(&hspi1, tx_data, 2, HAL_MAX_DELAY);
  HAL_GPIO_WritePin(TM1652_CS_GPIO_Port, TM1652_CS_Pin, GPIO_PIN_SET);
}

int main(void)
{
  HAL_Init();
  TM1652_Init();

  // 显示数字1
  TM1652_Write(0x68, 0x01);

  while (1)
  {
  }
}
