Resetting just one interrupt flag in TIFR
Do you think there is a simple way to reset just one timer interrupt flag (as TOV2 for example) in TIFR?   I have ATmega8A and I faced this situation while an external...

Measuring the average current of an acid battery
In a DC to AC inverter set, the in/out current of a battery could be periodic (mainly during its charging) or real DC (if discharged by a DC load, as LEDs connected directly...

Mains Voltage Versatile Detector
I design a mains voltage (220V, 50Hz) detector to provide, via an optoisolator as 4N35, the real time status of the mains voltage to the MCU interrupt pin (as of ATmega8A that I...

Old test in communications, DSB-SC
About 37 years ago, I built, as a test, a low power AM generator. Its output signal was: [1] double sideband suppressed carrier (DSB-SC) and, [2] the frequency of its ‘suppressed...

Raw USB port
To me, USB is rather a black box because I can’t access all technical resources and services that are available to most engineers in the world. So it is impossible for me to...

AS6.2 SP1, external interrupt triggered by software
From the datasheet of ATmega8: “The external interrupts are triggered by the INT0, and INT1 pins. Observe that, if enabled, the interrupts will trigger even if the INT0..1 pins...

Current Transformer and Ideal Rectifier
Since I am designing a meter (based on ATmega8) to measure the RMS current (50Hz mains power), I had a look at the application note “Atmel AVR465: Single-Phase Power/Energy Meter...

Precedence: Definitions and Macros
In building an assembly file (say for ATmega8, by AS6.2 SP1), which one happens first; replacing the defined symbols or the defined macros? In your opinion, which precedence is...

Copying a project in a solution
In general, there are copy functions for texts, files and directories.   Is it possible, inside a solution (AS 6.2 SP1), to copy a project and giving it a new name?  ...

An overview of some issues related to AVRstudio 6.2 and its simulatior
Hello, For about 20 years, I used writing my codes (in assembly) for Atmel C51 family (starting from AT89C2051). The only tools, I had, were the assembler TASM (via its DOS...
