To all who obviously responded to me after my last cries for assistance, thank you. I will read your responses as soon as I can. I have just returned home from a 5 day hospitalization. Let me make this short and simple: do **NOT** under any circumstances aspirate granulated sugar

Hi Jim, The code works great - as long as I don't go into power-down mode. While it is operating at full speed I never miss a switch press nor do I get any false triggers. I'm still trying so I haven't given up yet. Richard --- In AVR-Chat@yahoogroups.com, "Jim Wagner" wrote: > >

Richard - This does not address your immediate question but is the next step after you solve that. Its tht nasty business of switch debounce. If it wakes up on a pin change, then does it start executing when the timers are fully up and operating? I've never dealt with this situat

Hi John, According to the Mega48 manual (page 40) the following conditions will wake the chip from power-down mode: "Only an External Reset, a Watchdog System Reset, a Watchdog Interrupt, a Brown-out Reset, a 2-wire Serial Interface address match, an external level interrupt on I

Hi Folks, How do you set up the external interrupt on change to get the chip to come out of powerdown mode? I'm having trouble with getting my Mega48V to come out of powerdown. I need to read/debounce 4 tactile switches, power up a nRF905 chip, send the command and then go back t

Randy, If your switch is a KILL/ESTOP switching function, if memory serves correctly, it must be a mechanical type according to most electrical codes...and conservative design practice. We don't need to depend on any electronic component, with its indefinite or undefined life exp

Is it possible to use 16-bit constant labels in WinAVR inline assembly? Normally, in a assembly program, you can do: lds r16, 0x0412 (just a example) In mixed C/asm, some variables are stored in SRAM by the compiler. How to read them using 'lds' and 'sts' in inline assembly? asm

I can't check now, but maybe something to do with boot size. Your instruction to write flash (SPM?) has to be in the boot section, or it will not work, so if the boot section is zero... Take this with a pinch of salt, I'm a beginner with some things. Cat > On 7/18/07, Cat C wrote
