mosfet zener
I am using MOSFET H-BRIDGE to control the motor. Motor voltage is 9V MAX. To
fight EMF I'll have to use Zener catch diodes.
I am not sure which diode to use... what kind of ratings are important here?
pwm sound generation
Dear friends,
I need to play 8-bit, 11kHz, mono .wav files using an MCU. The sound quality doesn't have to be great.
The idea is to generate a 11 kHz PWM with varying duty cycle proportional to the current sample's amplitude. The PWM will be generated by AT91SAM7S64 MCU...
I'm trying to write a program in C++ to communicate with an AVR microcontroller's SPI via the LPT port.
I have to generate a clock (SCK) signal on one of the pins of the LPT. I am using the WinIO library. I'd like to have way to create a square wave of a given frequency (within some limit of...
