This is a raw printer mechanism that prints on a 2" roll of paper. It has a motor to advance the paper, the thermal print head which contains an array of dots across the width of the paper, and a couple of microswitches. My system uses a character mode LCD for setup but nothing e

Is it HPL compatible? Or what about Postscript compatible. If HPL you do escape code commands for drawing. If postscript you set a starting point and moveto commands. The other thing is the aspect is different than the screen. If the printer does 150 X 150 or 300 X 300 you can gr

Hi, all... I'm having some trouble with an SPI interface on the Mega32, which I'm using to communicate with a TI TLV2543 ADC. I'm programming the micro in C using avr-gcc. Here's my problem... using the SPI transmit code more or less straight from the Mega32 datasheet: SPDR = (ch

I have a remote control transmitter design where I'm trying to put the Tiny15 into Power Down mode. But although it appears to go into power down, it is still drawing 0.45mA. The data sheet says it should go down to about 2uA. I have eliminated all external circuitry from the des
