from machine import Pin, SoftSPI

def ID(agreement):
    #txbuf 需要将16进制转换为10进制
    txbuf =bytearray([17])
    rxbuf = bytearray(3)      # create a buffer
    spi = SoftSPI(baudrate=100000, polarity=1, phase=0, mosi=Pin(4), miso=Pin(16), sck=Pin(2))
    spi.init(baudrate=125000) # set the baudrate
    p16 = Pin(17, Pin.OUT)    # create output pin on GPIO16
    p16.value(1)             # set pin to on/high
    time.sleep(1)
    p16.value(0)             # set pin to on/high
    #给芯片发送SDATAC
    spi.write(txbuf) # write to MOSI and read from MISO into the buffer
    txbuf =bytearray([32,0,0])
    #给芯片发送读取ID的指令并且读取ID
    spi.write_readinto(txbuf, rxbuf) # write to MOSI and read from MISO into the buffer
    p16.value(1)             # set pin to on/high
    return rxbuf

以上是MicroPython的代码，

以下是Python代码

使用ESP32+MicroPython 配合Pyvisa等完成自动化测试，最后收集数据即可，大大提升了工作效率

附上美照，记得要先发Sdatac先才可以读取Id

楼主大佬的手机强呀，拍的效果不错。这个是几路的采集，有没有多路的，我有个20*4的，有没有解决方案呀？

这个是8路的

lugl4313820 · 发表于2023-12-28 20:43

xutong 发表于 2023-12-28 16:00 这个是8路的

8路是spi接口还是i2c接口呀，要是i2c路，采集完需要多少个时间呀。

lugl4313820 · 发表于2023-12-28 20:44

看了一下，spi接口的，看来读取速还是非常的快吧。

对，96ksps 最高可以

强啊！

在用这个片子做蓝牙采样，这蓝牙协议设计的什么破玩意，看不明白啊

用micropython可能还好？
