What can I use instead of WiringPi?
There are alternatives, however, and Python programmers in particular prefer microPython, GPIO zero and PPi. GPIO. Of these GPIO zero seems to be the most popular but wiringPi, because of its familiarly to Arduino programmers, does have a significant place and presence.
What is WiringPi?
WiringPi is a Cpp library for Raspberry Pi. With this library you can use many of the functionalities provided by the GPIO header: digital pins, SPI, I2C, UART, etc. Communicate between a Raspberry Pi (master) and an Arduino (slave) via I2C. Communicate between a Raspberry Pi (master) and an Arduino (slave) via SPI.
How do I install WiringPi on Raspberry Pi?
Head to the Wiring Pi directory. Then pull the latest changes from the origin. Then enter the following command. The ./build is a script to build Wiring Pi from the source files.
Is WiringPi still supported?
No more public releases. I’ll still be maintaining it for my own uses and clients, but for everyone else, please look at for alternative GPIO library for on-going projects.
What does GPIO Readall do?
gpio readall This reads all the normally accessible pins and prints a table of their numbers (wiringPi, BCM_GPIO and physical pin numbers), so makes for a handy cross-reference chart), along with their modes and current values.
What does Gpio Readall do?
Is WiringPi deprecated?
Since the release of the original Raspberry Pi single board computer, the WiringPi library by [Gordon] has been the easy way to interface with the GPIO and peripherals – such as I2C and SPI – on the Broadcom SoCs which power these platforms.
What is RS232 cable wiring?
RS232 Cable Wiring Diagrams RS232 Cable Wiring Diagrams Normally the RS232 port is used by touch-panel controllers and similar devices. However, Wireless Designer can connect to a receiver frame over a PC’s RS232 port as well. Use a cable wired as shown in the diagrams below.
What kind of serial port does wiringpi use?
Serial Library. WiringPi includes a simplified serial port handling library. It can use the on-board serial port, or any USB serial device with no special distinctions between them. You just specify the device name in the initial open function.
