ADXL355 SPI ESP32-IDF
Sure, here is an example of how to use the ADXL355 sensor with SPI in ESP32-IDF:
1. First, make sure you have the ESP32-IDF environment set up and the necessary SPI driver installed.
2. Include the necessary header files:
```c#include <stdio.h>
#include <freertos/FreeRTOS.h>
#include <freertos/task.h>
#include <esp_system.h>
#include <driver/spi_master.h>
```
3. Define the SPI bus parameters:
```c#define PIN_NUM_MISO25#define PIN_NUM_CLK26#define PIN_NUM_CS27```
4. Initialize the SPI bus:
```cspi_bus_config_t bus_config = {
.miso_io_num = PIN_NUM_MISO,
.sclk_io_num = PIN_NUM_CLK,
.quadwp_io_num = -1,
.quadhd_io_num = -1,
};
spi_bus_initialize(VSPI_HOST, &bus_config,1);
```
5. Attach the ADXL355 device to the SPI bus:
```cspi_device_handle_t spi;
spi_device_interface_config_t dev_config = {
.mode =0,
.clock_speed_hz =1000000, // Adjust as per your requirement .spics_io_num = PIN_NUM_CS,
.queue_size =1,
};
spi_bus_add_device(VSPI_HOST, &dev_config, &spi);
```
6. Define a function to read the X, Y, Z values from the ADXL355 sensor:
```cvoid read_adxl355(spi_device_handle_t spi, int16_t* x, int16_t* y, int16_t* z) {
spi_transaction_t t;
memset(&t,0, sizeof(t));
uint8_t tx_data[5] = {0x0B,0x00,0x00,0x00,0x00}; // SPI command to read X, Y, Z values uint8_t rx_data[5] = {0};
t.length =40; // Number of bits to send/receive t.tx_buffer = tx_data;
t.rx_buffer = rx_data;
spi_device_queue_trans(spi, &t, portMAX_DELAY);
spi_transaction_t* completed_transaction;
spi_device_get_trans_result(spi, &completed_transaction, portMAX_DELAY);
*x = (rx_data[1] <<8) | rx_data[2];
*y = (rx_data[3] <<8) | rx_data[4];
*z = (rx_data[5] <<8) | rx_data[6];
}
```
7. Create a task to continuously read and print the ADXL355 values:
```cvoid adxl355_task(void* pvParameters) {
int16_t x, y, z;
while (1) {
read_adxl355(spi, &x, &y, &z);
printf("X: %d, Y: %d, Z: %d\n", x, y, z);
vTaskDelay(1000 / portTICK_PERIOD_MS); // Delay for1 second }
}
void app_main() {
xTaskCreate(adxl355_task, "adxl355_task",2048, NULL,5, NULL);
}
```
Make sure to connect the appropriate pins of the ADXL355 sensor to the ESP32 board's SPI pins (MISO, CLK, CS). Adjust the pin numbers and SPI settings in the code according to your setup.
This example sets up a task that continuously reads the X, Y, Z values from the ADXL355 sensor using SPI and prints them every second.
esp32-idf sx1268数据打包
ESP32-IDF是一个基于ESP32芯片的开发框架,支持多种通信协议和外设。SX1268是一款LoRa收发模块,可以用于长距离无线通信。
在ESP32-IDF中,可以使用SPI接口和SX1268进行通信。数据打包的方法取决于具体的应用场景和通信协议。在LoRa通信中,通常采用LoRaWAN协议,需要按照协议规范对数据进行打包和解包。
以下是一个简单的示例代码,演示了如何使用ESP32和SX1268进行数据打包和发送:
```c
#include "esp_system.h"
#include "driver/spi_master.h"
#define PIN_NUM_MISO 19
#define PIN_NUM_MOSI 23
#define PIN_NUM_CLK 18
#define PIN_NUM_CS 5
#define SX1268_PAYLOAD_SIZE 256
spi_device_handle_t spi;
void sx1268_send(const uint8_t* data, uint8_t length)
{
uint8_t payload[SX1268_PAYLOAD_SIZE];
memset(payload, 0, SX1268_PAYLOAD_SIZE);
// Pack data according to LoRaWAN protocol
// ...
// Send data via SX1268
spi_transaction_t t;
memset(&t, 0, sizeof(t));
t.length = 8 * length;
t.tx_buffer = data;
spi_device_transmit(spi, &t);
}
void app_main()
{
spi_bus_config_t buscfg = {
.mosi_io_num = PIN_NUM_MOSI,
.miso_io_num = PIN_NUM_MISO,
.sclk_io_num = PIN_NUM_CLK,
.quadwp_io_num = -1,
.quadhd_io_num = -1,
};
spi_device_interface_config_t devcfg = {
.clock_speed_hz = 10 * 1000 * 1000,
.mode = 0,
.spics_io_num = PIN_NUM_CS,
.queue_size = 1,
};
spi_bus_initialize(HSPI_HOST, &buscfg, 1);
spi_bus_add_device(HSPI_HOST, &devcfg, &spi);
uint8_t data[] = {0x01, 0x02, 0x03};
sx1268_send(data, sizeof(data));
}
```
在sx1268_send函数中,首先根据LoRaWAN协议对数据进行打包,然后通过SPI接口发送数据。具体的打包和解包方法可以参考LoRaWAN协议规范。
