I am developing a system that needs to drive 4 stepper motors through 4 dual H-bridges, for each phase of movement the AVR will receive SPI messages stating how many steps each motor should do and ...
I'm trying to take 3 common anode RGB LEDs and hook up the cathodes of each to three of the PWM outputs on an ATMega328p and then in an ISR, multiplex between them all. The problem I'm running into ...
I'm multiplexing 32 LEDs in a 4:8 configuration on an ATMega328 and am trying to dim them with what is probably a completely naive understanding of PWM. Note: I'm multiplexing them directly with 12 ...
This question builds upon this previous one How to interpret output of 3-pin computer fan speed sensor? which was asking about the 'sense' wire output from computer fans. I am designing a fan ...
In pseudocode I want to do following: ...
