我需要使用MAX31865 SPI通信读取温度数据。首先,我尝试读取4字节数据:
import machine
import ubinascii
spi = machine.SPI(1, baudrate=5000000, polarity=0, phase=0)
#baudrate controls the speed of the clock line in hertz.
#polarity controls the polarity of the clock line, i.e. if it's idle at a low or high level.
#phase cont
我试图使用这个将数据存储到ESP32闪存中。我特别使用这个来写入和读取浮点值。我刚刚在代码中添加了一个Serial.println(“错误”),如下所示-
for (uint8_t i = 0; i < arrayLen(floatAddr); i++)
{
if (flash.writeFloat(0x00, testFloat[i]))
{
Serial.print(testFloat[i]);
Serial.print(" written to 0x");
Serial.println(floatAddr[
在我的应用程序中,我需要包含来自的组件的依赖项。
当我构建项目时,工具套件检测到依赖项,但不能更新组件,因为它说组件管理器尚未启用。
