tiny26 internal ADC amplifier
Hello, I see that the tiny26 has a internal gain amplifier for the ADC. Does this amplifier reduce the input current requirements of the S/H? The datasheet is rather vague on this...

Tiny high efficiency audio DAC
Hi, I need a very small and highly efficient audio DAC, capable of driving a 0.15Watt 20mm mini speaker. Power source: 3V lithium coin cell. 20mm speakers are available with 8ohm...

data loss / error correction
This is a tricky one... I have a PC communicating with a AVR using a unidirectional serial link (RS232). The PC can send data to the AVr, but the AVR cannot send data to the PC....

RC osc. calibration at 3.3V
Reading the atmel datasheets (mega8L datasheet to be exact) I find that the calibration byte for the internal oscillator only works for 5V operation. At 3.3V operation the...

OT: line scan cameras
Quite a bit off topic, but at least Atmel is one of the leading manufacturers of digital line scan cameras, and I suspect that I'am not the only one in this forum that have worked...

DTR reset.
I've built a serial port connected AVR based device that supports configurable baudrates. Now, if some software screws up and mess up the baudrate to some unknown rate, there's...

Atmel PLD JTAG cable (slightly off topic)
Not AVR's but at least it's atmel.. I'am looking for the schematics/pinout for Atmel's PLD ISP cable (JTAG) used for ATF15xxx PLD's. Might be the same cable as for JTAG capable...

Sometimes it's hard to justify the use of AVR's..
Make no mistake, I love AVR's, and I use them whenever I can. But... I recently found out about this 64pin tqfp ARM7 (32bit RISC you know..) based MCU with 128kB built in flash,...

Where did all my SRAM go? :)
I'am using a 2313 and AVR-GCC version 2.95.2 with the -O3 option. The 2313 has 128Byte SRAM and of course, 32 registers. I'am using global variables only, to better keep track of...

Mega8 MLF
I was searching for a physically small AVR (few I/O) with lots of SRAM and EEPROM, and the perfect match is of course the Mega8 in a MLF package. That thing looks sweet! It looks...

Very short (5mm) wireless communication
I have a small AVR monted on a rotating fan. I need serial communications between the AVR and a (non rotating ;) PC. Not necessarily both ways communication, the PC has to be able...
