# Component: MCP3201 MCP3201 device is a successive approximation 12-bit Analog-to-Digital (A/D) Converter with on-board sample and hold circuitry. The device provides a single pseudo-differential input.Differential Nonlinearity (DNL) is specified at ±1 LSB, and Integral Nonlinearity (INL) is offered in ±1 LSB (MCP3201-B) and ±2 LSB (MCP3201-C) versions. Communication with the device is done using a simple serial interface compatible with the SPI protocol. The device is capable of sample rates of up to 100 ksps at a clock rate of 1.6 MHz. The MCP3201 device operates over a broad voltage range (2.7V-5.5V).Low-current design permits operation with typical standby and active currents of only 500 nA and 300 μA, respectively. ## Add component to your project Please use the component manager command `add-dependency` to add the `mcp3201` to your project's dependency, during the `CMake` step the component will be downloaded automatically ``` idf.py add-dependency "espressif/mcp3201=*" ``` ## Example of MCP3201 usage ```c static spi_bus_handle_t spi_bus = NULL; static mcp3201_handle_t mcp3201 = NULL; int16_t data; // Step1: Init SPI bus spi_config_t bus_conf = { .miso_io_num = SPI_MISO_IO, .mosi_io_num = -1, .sclk_io_num = SPI_SCLK_IO, }; spi_bus = spi_bus_create(SPI2_HOST, &bus_conf); TEST_ASSERT(spi_bus != NULL); // Step2: Init MCP3201 spi_device_config_t dev_cfg = { .mode = 0, .clock_speed_hz = SPI_FREQ_HZ, .cs_io_num = SPI_CS_IO, }; mcp3201 = mcp3201_create(spi_bus, &dev_cfg); // Step3: Read ADC value mcp3201_get_data(mcp3201, &data); ESP_LOGI(TAG, "MCP3201:%d,Convert:%.2f", data, 1.0f * data * (3.3f / 4096)); ```
