答案对人有帮助，有参考价值 0 你需要什么样的处理器或语言驱动程序？ SPI接口非常易于使用。我正在尝试将它与Tiva LM4C129处理器一起使用，该处理器具有SPI硬件模块，但它几乎同样易于爆炸。以下是C中用于读写LSM303D寄存器的基本例程:(假设您的处理器具有SPI硬件） uint8_t read_LSM303D_reg（uint8_t reg） { uint8_t值; CLEAR_LSM303_CHIP_SELECT; SSI3_DR_R = reg \| 0x80; //发送带有'read'位设置的寄存器号 SSI3_DR_R = DUMMY_DATA; 而（SSIBusy（SSI3_BASE））; SET_LSM303_CHIP_SELECT; value = SSI3_DR_R; value = SSI3_DR_R; return（value）; } void write_LSM303D_reg（char name，uint8_t reg，uint8_t value） { uint8_t temp; CLEAR_LSM303_CHIP_SELECT; SSI3_DR_R = reg; SSI3_DR_R =值; 而（SSIBusy（SSI3_BASE））; SET_LSM303_CHIP_SELECT; temp = SSI3_DR_R; //清空FIFO temp = SSI3_DR_R; } 也许这有帮助吗？帕特里克我说''尝试''因为LSM303D不适合我们，我们无法从ST获得任何帮助！我可以很好地读写寄存器，大多数时候我都可以获得加速度计和磁力计的良好值。有一段时间，LSM303D中的加速度计似乎锁定，使得X和Z值是相同的值并且永远不会改变，Y值通常与X和Z的值相同但是变化+/- 1或2时不时。芯片的其余部分继续正常工作，但加速度计被锁定在这种状态，似乎没有人想要解决这个问题。希望你不要遇到同样的问题？以上来自于谷歌翻译以下为原文 What processor or language do you need the driver for? The SPI interface is very easy to use. I'm trying to use it with a Tiva LM4C129 processor, which has a SPI hardware module, but it's almost as easy to bit-bang. Here are the basic routines in C for reading and writing LSM303D registers: (assuming your processor has SPI hardware) uint8_t read_LSM303D_reg(uint8_t reg) { uint8_t value; CLEAR_LSM303_CHIP_SELECT; SSI3_DR_R = reg\|0x80; // send register number with 'read' bit set SSI3_DR_R = DUMMY_DATA; while (SSIBusy(SSI3_BASE)); SET_LSM303_CHIP_SELECT; value = SSI3_DR_R; value = SSI3_DR_R; return (value); } void write_LSM303D_reg(char name, uint8_t reg, uint8_t value) { uint8_t temp; CLEAR_LSM303_CHIP_SELECT; SSI3_DR_R = reg; SSI3_DR_R = value; while (SSIBusy(SSI3_BASE)); SET_LSM303_CHIP_SELECT; temp = SSI3_DR_R; // empty the FIFO temp = SSI3_DR_R; } Maybe that helps? Patrick I said ''trying'' because the LSM303D is not behaving for us and we can't get any help from ST! I can read and write the registers just fine, and I get good values for the accelerometer and magnetometer most of the time. Once in a while, the accelerometer in the LSM303D seems to lock up such that the X and Z values are the same value and never change, and the Y value is usually the same value as X and Z but varies by +/- 1 or 2 every now and then. The rest of the chip continues to work just fine, but the accelerometer is locked into this state, and it appears that no one at ST wants to address the issue. Hope you don't run into the same problems?
