configured as a PWM output. In this example. I will gpio0,gpio1. The GPIO2 is configured as a soft PWM output. The PIN assignment table for the Raspberry Pi is for example with what you see: The RGB LEDs I use are common cathode, with the Raspberry Pi connection method suc

not possible to have a pi3-miniuart-bt-overlay, this can also, probably because the raspberry dispatched factory date different module name different , I found someone on the internet to provide Pi3-miniuart-bt-overlay module)Comment out the other UART settings in/boot/config.txt, this is best commented out, uart_enable=1 also commented out! remember!sudo apt-get updatesudo apt-get upgradesudo rebootThe UART from the start of the

Gpio Library core function, of course, is the operation of Gpio, Gpio is the "general input/Output" interface, such as lighting a LED, relays, or through the IIC SPI 1-wire and other protocols, read, write data, this is the use of Gpio, can say no gpio, Raspberry Pi can only be used as a small computer, with a gpio, it is upgraded to a controller. First of all, how to operate a digital volume (high and low

Raspberry Pi advanced GPIO library, wiringpi2 for python using notes (4) practice DHT11 decoding, gpiodht11 DHT11 is a temperature and humidity sensor with calibrated digital signal output. Precision humidity +-5% RH, temperature +-2 ℃, range humidity 20-90% RH, temperature 0 ~ 50 deg C. The encapsulated modules I bought contain the pull-up resistor. After checking the

The DHT11 is a temperature and humidity sensor with calibrated digital signal output. Precision humidity +-5%RH, temperature +-2℃, range humidity 20-90%rh, temperature 0~50℃. I bought a good package of modules, the top with a pull-up resistor, directly to the Raspberry Pi can be gray, purple, blue respectively represents data, 3.3V, 0V, to the Raspberry

project, the entire framework of the program has been set up, we directly compile the program to tryCompile no problem, below we expand the left side of the forms file directory, double-click the Mainwindow.ui file, and then we add two buttons on this interface, two buttons respectively control the Raspberry Pi one pin output high and low level, as shown in:Modi

Before the text Because recently busy review exam, so did not pick up the Raspberry Pi car, until yesterday, finally empty time to put the code down and share with you. BodyIn the second of the Raspberry Pi Trolley series, there are two ways to define the pin o

Recently want to use Raspberry Pi control model of the ESC, so studied the next PWM, seemingly control the ESC is troublesome, because the ESC needs to send a few specific signals to start, and then to enter the control mode, today first understand PWM, slowly toss. The following program pro-test is available, I use the Raspberry
