Re: Ultibo core a bare metal environment for Raspberry Pi

It's best news for me in hardware development of ARM MCUs :D
I tested all examples. Very nice project.
It can change the game of embedded world.
I think about mixing FpGui with Ultibo.
Link: http://fpgui.sourceforge.net/
Is it possible?

In desktop file manager:
Right click on the executable file and click on Properties. Then go to Permissions Tab and check on Make the file executable.
Or
In Terminal go to your program folder and type below:
./executablename
or

Re: Lazarus and wiringPi

Hi Gordon Thanks for your great work. You are not very kind with PASCAL. Many hardware developers love PASCAL because it is fastest complement for their hardwares. Delphi or Lazarus is best RAD for anyone that don't want to be a full time software developer (same Gordon) :D For example, my projects ...

Re: Using wiringPiISR

As Paul said, Interrupts must be defined just in the begin of the program. Example: wiringPiISR (pinx, INT_EDGE_BOTH, &my_intr_function); Then, in the my_intr_function you can read pinx as normal GPIO to find its rising or falling. Example: if ( digitalRead(pinx) == 1) rising_edge_Interrupt_function...

Re: Using wiringPiISR

Unfortunately, I don't have an appropriate answer to your question. Still, it seems we are working on the same issue. I'm trying to trigger a photo flash bulb with a GPIO. The GPIO is connected to an opto coupler with triac output, the triac in its turn is connected to the input of the flash. Accor...

Now I try to use this function to analyze the transition from high to low and from low to high on the same pin. That means I w...

Re: wiringPiISR ISR.c example question

I want to test wiringPI ISR capability in this week.
For testing Edge triggered interrupts we cant use simple pushbutton switches, because they have bounced outputs that make several edges on gpio.
