I thought about the 555. The problem I thing is that probably I am not able to generate a variable frequency generator with 555 and that's why I am thinking to use a microcontroller (if I am wrong please tell me).
If I will use the 555 I will need and the differential driver in order the square...
This is how I was thinking to drive it...One more question. I am thinking of not using a timer. The way I am thinking is the following...
loop:setb Px.0 ;high pulse
delay ;delay for 12.5μsec
crl Px.0; low pulse
delay; delay for 12.5μsec
jmp loop
Will I need to connect a D/A...
I want to build an ultrasonic generator (variable frequency if possible-if not at 40kHz) with the use of a 89c51 for use in ultrasonic cleaning tank. The reason for the selection of the specific MCU is that i have some experience in programming it with Assembly language in other projects.
My...
PC-MCU communication
Hello to everyone,
I want to make a project with mcu's and i want to control it through my pc and i want to program an interface to control it through my laptop.But my laptop don't have serial port.So I have to built an interface that can read from usb port.Right?
But...
