Strange problem for me.. new territory. I appreciate every opinion and experience you have to offer on this topic.
I need to record a button click. This is for user-experience thing. I have Babyface Pro FS and a very good and expensive microphone. What are my options to automate this thing with...
I have never heard of this unit before. I have worked in many different tech things.. amateur tv, embedded systems, robotics. And now I am asked to measure a devices sound as "Sone" units. If somebody has experience about those unit... well I don't even know what exactly what to ask. What is...
I have this design for current measurements around uA to mA range.. maybe in the future few amps. Nice IC-chip amplifier for this purpose (INA21x). I have a relay to switch between different shunts to little bit change the range.
The problem is calibration. Could there be a design that I could...
Just a general interest.. studying. I have built an electric guitar from scratch, but never learned to play it. I like woodworking and electronics.. programming.
Do you know how a violin works? The bow is a random number generator and the violin resonates on a specific frequency.. but it needs...
No, you vary the compare value. The same way you do traditional pwm. Only difference is that the counter values do not come in order. They come in random order.
The same way than in a traditional microcontroller pwm module. But instead of using a linear counter, this would use evenly distributed random numbers.
Traditional:
Take timer value, compare with desired duty cycle, set output high or low.
Random pwm:
Take random value, compare with desired...
I'm talking about how the final squarewave PWM signal is generated. Maybe a picture helps.
When a counter counts from 0 to 255 and then rolls over to 0 and keeps counting. It is a sawtooth pattern.
There are many benefits of using random pwm. Main benefit is reduced electromagnetic...
I think this fits under Microcontrollers (embedded systems). This is just an idea I had few years ago and now I'm considering developing and testing it again.
Pulse Width Modulation (PWM) is usually generated with a counter and a compare value. When the counter is below the compare value, the...
Of course calling the "digitalWrite" function is slower than direct write to register. The "digitalWrite" function is designed to be thread-safe and there is a lot of overhead. It disables interrupts, saves the execution context and pushes given parameters to stack.. then writes the pin changes...
Hello
So, it is weekend. I had this idea of making fun of flat earth "movement". The idea is to draw two pictures about how gravity works.
Picture 1 explains how gravity works on a big planet. My simple understanding is that you are pulled towards the mass-center of object.. always. Is this...
