FIFO on MPU6050
When an interrupt is received, you can set a flag. In the main program loop, you check for the flag and read the FIFO from the MPU-6050. Are you sure you want to do this ? For the...

Usage of 'if condition'
Can you tell how do you do know how long 1 second is ? With a software delay, or a timer ? Did you know that in the "Projects" section are some projects for rpm measurement ?

Usage of 'if condition'
How do you measure the RPM and how do you measure time ? Perhaps you have already a timer running ? I would create a timer with an interrupt of 10Hz, as a "system timer". The RPM...

High Voltage DC measurement with ISOLATION
Using a resistor divider is a simple and accurate way to measure high voltages. But often the current is too small to be used with a linear optocoupler. A resistor divider with...

L293E question
According to the datasheet that is possible. But you have to do this with an analog circuit with a few comparators. See figure 11 of the datasheet. I don't know if you can do this...

Why bother writing it yourself. In the project section are many serial functions. Like the one I updated : https://www.avrfreaks.net/index.p...

Automotive DC-DC converter issues
It depends on the input voltage and the current. Is it for example 50V for a few seconds, or only a spike of 200V for a few ms ? What is the current ? Do you have to use that DC-...

need solution on voltage level translation
Do you only want to read the serial data, or must you also write something ? Your controller, is that the ATmega16 at 3.3V ? Do you have a 5V voltage in your controller ?...

EEProm Storage Technique. Will this work?
You need an extra copy in ram (MyStructArray), the extra ram usage is the major disavantage. Writing only the data that has changed, is something that is done most of the time. If...

Spawn and yield in AVR
The example you found is using a queue to place funtions pointer in, that needs to be executed. The code is complicated and only for experienced software engineers. Do you have to...

Is there a H-Bridge driver ic for 40kHz piezo ?
I read that 23kHz is the most annoying to dogs. So I don't want its resonance frequency. If you check the graph of the frequency response, the KEMO L010 seems to have a peak at...
