Micropython SPI 驱动 ADXL355 寄存器读写示例

由于缺乏 ADXL355 设备，以下为示例代码，仅供参考：

import machine
import time

# 定义引脚
DRDY = machine.Pin(23, machine.Pin.IN)
INT1 = machine.Pin(16, machine.Pin.IN)
CS = machine.Pin(21, machine.Pin.OUT)
SCLK = machine.Pin(14, machine.Pin.OUT)
SDA = machine.Pin(13, machine.Pin.OUT)
MISO = machine.Pin(12, machine.Pin.IN)

# 初始化SPI
spi = machine.SPI(1, baudrate=1000000, polarity=0, phase=0)

# 定义读写寄存器函数
def write_register(address, value):
    CS.value(0)
    spi.write(bytearray([address, value]))
    CS.value(1)

def read_register(address):
    CS.value(0)
    spi.write(bytearray([address | 0x80, 0x00]))
    value = spi.read(1)[0]
    CS.value(1)
    return value

# 测试读写寄存器
write_register(0x2C, 0x01) # 设置寄存器 0x2C 为 0x01
print(read_register(0x2C)) # 读取寄存器 0x2C 的值
time.sleep(1)
write_register(0x2C, 0x02) # 设置寄存器 0x2C 为 0x02
print(read_register(0x2C)) # 读取寄存器 0x2C 的值
