# 1 - Introduction Sensor driver for ASM330LHH sensor written in C programming language. This repository contains the sensor driver files (.h and .c) to be included, or linked directly as a git submodule, in your project. The driver is MISRA compliant and the documentation can be generated using the [Doxygen](http://www.doxygen.org/) tool. In order to `clone` the complete content of the repository folder, use the command: ``` git clone https://github.com/STMicroelectronics/ASM330LHH-PID/ ``` Some examples of driver usage can be found [here](https://github.com/STMicroelectronics/STMems_Standard_C_drivers). ------ # 2 - Integration details The driver is platform-independent, you only need to define two functions for read and write transactions from the sensor hardware bus (ie. SPI or I²C). **A few devices integrate an extra bit in the communication protocol in order to enable multi read/write access, this bit must be managed in the read and write functions defined by the user.** Please refer to the read and write implementation in the [reference examples](https://github.com/STMicroelectronics/STMems_Standard_C_drivers/tree/master/asm330lhh_STdC/examples). ### 2.a Source code integration - Include in your project the driver files of the sensor (.h and .c) - Define in your code the read and write functions that use the I²C or SPI platform driver like the following: ``` /** Please note that is MANDATORY: return 0 -> no Error.**/ int32_t platform_write(void *handle, uint8_t Reg, const uint8_t *Bufp, uint16_t len) int32_t platform_read(void *handle, uint8_t Reg, uint8_t *Bufp, uint16_t len) ``` - Declare and initialize the structure of the device interface: ``` xxxxxxx_ctx_t dev_ctx; /** xxxxxxx is the used part number **/ dev_ctx.write_reg = platform_write; dev_ctx.read_reg = platform_read; ``` - If needed by the platform read and write functions, initialize the handle parameter: ``` dev_ctx.handle = &platform_handle; ``` Some integration examples can be found [here](https://github.com/STMicroelectronics/STMems_Standard_C_drivers/tree/master/asm330lhh_STdC/examples). ### 2.b Required properties > - A standard C language compiler for the target MCU > - A C library for the target MCU and the desired interface (ie. SPI, I²C) ------ **More Information: [http://www.st.com](http://st.com/MEMS)** **Copyright (C) 2021 STMicroelectronics**
