2021.09.01. Low-cost Robotics Group at URJC

Starting this academic year, I focus my research on low-cost robotics, channeling my efforts into the Low-cost Robotics Group at Rey Juan Carlos University, which I lead and which aims to develop low-cost robotic systems that provide a real solution to the needs posed by society.

That is why, from this point on, my research will be published in the Low-cost Robotics Group's GitHub site, through the repositories of the different projects I lead, and this Research tab will no longer be maintained.

2021.07.08. Raspberry Pi SW interrupts through GPIO pins

Interrupts are a very important mechanism to be used to receive info from sensors. Otherwise, the CPU could be collapsed when polling the pin (to which the sensor is connected) status value.

Since Raspberry Pi doesn't support hardware interrupts (as Arduino does), they have to be simulated using software interrupts and the pull_up_down sw resistors. Using the example shown in this figure, the sw interrupts mechanism could be assimilated.

The code can be found in this GitHub repository.
