这是我的程序
spi.send_recv(spi.SPI_1,string.fromHex(_WAKEUP))
sys.wait(100)
spi.send_recv(spi.SPI_1,string.fromHex(_RESET))
sys.wait(100)
spi.send_recv(spi.SPI_1,string.fromHex(_SDATAC))
while true do
spi.send_recv(spi.SPI_1,string.fromHex("20"))
spi.send_recv(spi.SPI_1,string.fromHex("00"))
spi.send_recv(spi.SPI_1,string.fromHex("00"))
sys.wait(100)
end
逻辑分析仪测得 发送的都是正确的数据
这是我接收到的数据
左侧是发送的数据 右侧是返回的数据

我的 CLKSEL, PWDN，RESET 引脚 都是硬件上拉
我测的电压
AVDD 3.1V
AVSS 0V
DVDD 3.1V
GND 0V
VCAP1 1.2V
VCAP2 1.6V
VCAP3 4.9V
VCAP4 235mV
VREFP，VREFN 都是0V
请帮我看下是什么问题
