How to fix low LED light? Generally on the AVR, when a normally-bright LED appears very dim, it is often because the anode is connected to Vcc (+5 or +3.3) on the prototype and is disconnected from Vcc on...

DS18B20 ROM reads alternate bytes Hello,
If you are using a Mega328p at 16MHz then you should be modeling your application on an Arduino Nano/UNO first. The UNO/nano has the same AVR configuration and...

Seeking resources for learning assembly (ATMEGA 4809) Instead of suggesting AVR assembler tutorials and resources, I suggest that you reflect on why you would want to or need to learn assembler for the Mega4809. Assembler is...

Why can't I drive ws2812b leds with an attiny24 ? The 20MHz ATtiny24 has enough time to determine the proper logic level for the WS2812 bit and to make its output pattern, when it is being run in assembly language. With a...

I dont know how to send my code to arduino Take everything that is in the main() function and split it into two functions. Lines that run only once near the beginning go into the void setup() function. ...

Split from: R2R Ladder 8-bit DAC question #2 Since you are interested in low-cost DAC interfacing on the AVR, allow me to suggest simply adding another IC to your circuit. The 8-pin SOIC-sized (It's small,...

Output defined count of clock cycles without cpu? Do you have four planes of LEDs (16 in an X-Y plane) with one 16-channel LED-driver IC multiplexing the four planes one at a time? And each of the individual planes is...

Get an ATTINY10 to wake up on button press Hello,
Delay(uint16_t myDelayInMilliseconds) should use the timer to update the count of an unsigned long volatile variable 'millis' every thousandth of...
Program and sending data with same cable IF you want to program an AVR and exchange data with it using a USB cable, get a few of these USB/Serial converters: https://www.ebay.com/itm/6-Pin-U...

Since the tiny5's only cost 30 cents USD, YOu could try one and see. I would believe that the +12 Voltage on reset would override any normal ATtiny mode. Are you...

Interrupts should be very short. They should set/clear global volatile boolean flags to the main program. I suggest naming these booleans in the format: is(...
