Example code for talking to aTMP102I2C thermometer, like those available from Sparkfun, for example. Rather heavily based on some code I found in the forums, some samples, and a bit of personal investigation to make it all work. Based on my testing, the sensor overreads by around 5 degr...
There are both 7- and 8-bit versions of I2C addresses. 7 bits identify the device, and the eighth bit determines if it's being written to or read from. The Wire library uses 7 bit addresses throughout. If you have a datasheet or sample code that uses 8 bit address, you'll want t...
Note the above code snippet.Press S1 LED1 turns on and stays on. Press S2 and LED1 turns off and stays off. (This could also be a motor control for example.) In each case pressing S1 or S2 returns a 1 or 0; the "if" command does the rest....
arduino+i2c的1602屏显示串口输入数据 笔记 所需尺寸不同(16x2)。 pcf8574模块蓝色选钮控制的字符灰度,不正确的灰度会导致液晶屏无显示,但是可以控制亮度(我遇到的1602不显示问题)。在非I2c显示器上使用LCD_I2c库,反之亦然...; A5这个sda scl口是固定的,所以在写程序时候都不用写管脚声明,只需要声明管脚i2c地...

bus compatible sensor but we can't change the address. So, I use the TCA9548a Adafruit board I2C multiplexer. I can run only one VL680 directly on my I2C bus but it won't work trough the multiplexer. Datasheet is not clear and I find only code for Arduino or bad Python example. ...
把esp32和mpu60插入面包板,用跳线连接二者,使用i2c通信协议,一共需要四根线,分别是电源正vcc,地gnd,数据sdl和时钟scl。 打开arduino ide,在库中搜索mpu6050,然后安装它。第一个库,我的已经安装好了,如下图。 打开file-example-mpu6050-mpu6050_raw,有现成的实例代码。
