Switches to the next location in the navigation history. Goto the previous part of the current word. Goto the next marker in the current document. Goto the previous marker in the current document. Set a marker on the current line, or clear the marker if there already is one. If this keyboard shortcut is pressed again, the cursor is moved back to the first brace.
If the cursor is ahead or behind a brace, then it is moved to the brace which belongs to the current one. The cursor position and or an existing selection will not be changed.įocuses the Go to Line entry (if visible) or shows the Go to line dialog. Scrolls the current line into the centre of the view. If the line is not wrapped, it behaves like Go to End of Line. Move the caret to the end of the display line. If the line is not wrapped, it behaves like Go to Start of Line. This is useful when you use line wrapping and want to jump to the start of the wrapped, virtual line, not the real start of the whole line. Move the caret to the start of the display line. Behaves differently if smart_home_key is set. Just reinstall, no need to uninstall the old one.Move the caret to the start of the line. Upgrading to a newer version of the library #define LED_YELLOW(state) bcm2835_gpio_write(RPI_V2_GPIO_P1_26, !state) #define LED_GREEN(state) bcm2835_gpio_write(RPI_V2_GPIO_P1_24, !state) #define LED_GREEN(state) bcm2835_gpio_write(RPI_BPLUS_GPIO_J8_40, !state) //RPI1B+ & RPi2B See the header file for all of the functions. See here for a better solution if you need to avoid this. This is because the function allows the linux scheduler to know the process is sleeping and decide to move on to another process. Problems With The LibraryĭelayMicroseconds() is a handy function but if you use it a lot you’ll find operation takes much longer than it should. Use CTRL+Break or CTRL+SHIFT+C to stop the exe. If you connect the positive pin of a 5V LED to pin 11 of the P1 header it should be blinking. You can compile one of the examples using this:Īnd then run the blink exe with this command: Trying out an example project using the command line C compiler In a simple makefile for a project with a single file called main.c: When you compile you also need to include -lbcm2835 so the libraries object file is added to the final compilation.įor example at the command line: gcc clk.c -o clk -lbcm2835 Right click the project > Properties > Build > Linker > In the ‘Libraries’ section press the ‘…’ button > Add Option… > Other Option > Enter: -lbcm2835 Using the Library In A Geany Project
When you compile you also need to include -lbcm2835 so the libraries object file is added to the final compilation. Including the library header file #include (The sudo is needed to elevate permissions to the root user) (The following instructions are based on the instructions in the bcm2835.h file so if something doesn’t work check there to see if the instructions have changed)Ĭhange to the directory the files we’re unzipped into (Change the directory version number to match your downloaded version) cd bcm2835-1.XX The files will be unzipped into a folder called “/home/pi/bcm2835-#.#” where # is the version number. Unzip the downloaded file (Change the file version number to match your downloaded version) tar zxvf bcm2835-1.XX.tar.gz
#GEANY RASPBERRY PI INSTALL#
Install the library files using the following commands You can do this using wget on the command line: tar.gz file from the library page to your “/home/pi/” root directory. If you are using the GUI then open the command prompt using Menu > Other > LXTerminal XX to match the current library version number, e.g. This library also supports the RPi2 and upwards, with the bcm2836 and upwards chipsets Installing The Library
