我想用新唐的硬件I2C驱动OLED模块，之前在STM32上做的是可以的。现在换成相同功能的新唐的函数发现失败了，不知道是不是我哪儿没有配置正确。void OLED_Write_cmd(uint8_t cmd)
{
// HAL_I2C_Mem_Write(&hi2c2, 0x78, 0x00, I2C_MEMADD_SIZE_8BIT, &cmd, 1, 0x100);
while(I2C_WriteByteOneReg(I2C0,OLED_ADDR,0x00,cmd));
}
void OLED_Write_data(uint8_t data)
{
// HAL_I2C_Mem_Write(&hi2c2, 0x78, 0x40, I2C_MEMADD_SIZE_8BIT, &data, 1, 0x100);
while(I2C_WriteByteOneReg(I2C0,OLED_ADDR,0x40,data));
}
初始化中跟I2C0时钟和管脚的配置为
/* Enable I2C0 peripheral clock */
CLK_EnableModuleClock(I2C0_MODULE);
/* Set I2C0 multi-function pins */
SYS->GPG_MFPL = SYS_GPG_MFPL_PG1MFP_I2C0_SDA | SYS_GPG_MFPL_PG0MFP_I2C0_SCL;
