Arduino Tutorial #2 Multiplexing and Charlieplexing LEDs

WebThis unusual multiplex technique is used by the MAX6950, MAX6951, MAX6954, MAX6955, MAX6958, and MAX6959 LED display drivers. Charlieplexing reduces driver pin-count by using some pins alternately as cathode and anode drivers. This differs from the standard LED multiplex connection, which uses separate driver pins for anodes and cathodes. WebMay 5, 2024 · As the subject shows, I'm wondering about the benefits of charlieplexing a project I'm just beginning. I understand the methodology but have never used charlieplexing and wonder if I will get better results with one over the other. A description of what I want to accomplish will certainly be in order.

WebJul 23, 2024 · The PIOs built into the RP2040 microcontroller allow this refresh to be performed automatically, without processor intervention. This Arduino library uses the PIO (Programmable IO) module of RP2040 microcontroller for handling 5-leds and 6-leds charlieplexing: the 6-leds version requires 11 PIO instructions, and 3 consecutive GPIO … WebServo motors are used in remote control vehicles and robotics. Most servo motors are not continuous; that is, they cannot rotate all the way around but rather just over an angle of about 180 degrees. The position of the servo motor is set by the length of a pulse. The servo expects to receive a pulse at least every 20 milliseconds.
