请教大神怎样通过HAL I2C函数设置寄存器值呢？

问答对人有帮助，内容完整，我也想知道答案 0 我使用 unico GUI 将 .ucf 文件转换为 .h。但我无法通过 HAL I2C 函数设置寄存器值。我无法获得任何决策树结果。 /* ****************************************************************************** * @file LSM6DSOX_configuration.h * @author Sensors Software Solution Team * @brief This file contains the configuration for LSM6DSOX_configuration. * ****************************************************************************** * @attention * * © Copyright (c) 2020 STMicroelectronics. * All rights reserved. * * This software component is licensed by ST under BSD 3-Clause license, * the "License"; You may not use this file except in compliance with the * License.

答案对人有帮助，有参考价值 0 在寄存器中写入 MLC 配置之前，您是否在 EMB_FUNC_EN_B (05h) 寄存器中写入 MLC_EN 位来启用 MLC？供您参考，例如，在FP-SNS-ALLMEMS1驱动程序（附件）中可以找到 LSM6DSOX MLC 设置的一般过程： /** * @brief Enable Machine Learning Core.[set] * * @param ctx read / write interface definitions * @param val change the values of mlc_en in * reg EMB_FUNC_EN_B and mlc_init * in EMB_FUNC_INIT_B * / int32_t lsm6dsox_mlc_set(stmdev_ctx_t ctx, uint8_t val) { lsm6dsox_emb_func_en_b_t reg; int32_t ret; ret = lsm6dsox_mem_bank_set(ctx, LSM6DSOX_EMBEDDED_FUNC_BANK); if (ret == 0) { ret = lsm6dsox_read_reg(ctx, LSM6DSOX_EMB_FUNC_EN_B, (uint8_t)®, 1); } if (ret == 0) { reg.mlc_en = val; ret = lsm6dsox_write_reg(ctx, LSM6DSOX_EMB_FUNC_EN_B, (uint8_t)®, 1); } if ((val != PROPERTY_DISABLE) && (ret == 0)){ ret = lsm6dsox_read_reg(ctx, LSM6DSOX_EMB_FUNC_INIT_B, (uint8_t)®, 1); if (ret == 0) { reg.mlc_en = val; ret = lsm6dsox_write_reg(ctx, LSM6DSOX_EMB_FUNC_INIT_B, (uint8_t)®, 1); } } if (ret == 0) { ret = lsm6dsox_mem_bank_set(ctx, LSM6DSOX_USER_BANK); } return ret; } 另一件要检查的事情是 I2C 是否正常工作，例如读取 WHO_AM_I (0Fh) 寄存器并获得正确的 ID。
