Back [05:04:56]<_ami_> Blog abt how to use ext. clock with avr and overclocking.
[05:05:02]<_ami_>http://amitesh-singh.github.io/avr/2016/09/04/use-ext-clock-as-hearbeat-to-avr.html [07:01:45]<Lambda_Aurigae> _ami_, it's a nifty way to clock an AVR....I've used a 555 timer, a switch, a button, and a variable resistor to run an AVR from DC to 1MHz(give or take)
[07:02:01]<Lambda_Aurigae> not nearly as accurate
[07:02:11]<Lambda_Aurigae> but let me run it down nice and slow or speed it way up.
[07:05:23]<_ami_> i have not done clocking avr by 555 timer. i think other mcu can also be used if it has toggling pin. bitbang or pwm
[07:05:29]<Lambda_Aurigae> yup.
[07:05:31]<Lambda_Aurigae> it can.
[07:05:45]<Lambda_Aurigae> that's how some programmers generate clock for when you screw up fuse settings.
[07:06:10]<Lambda_Aurigae> I also used a microchip digital pot connected to the 555 just as a test.
[07:06:19]<Lambda_Aurigae> the AVR could control its own speed.
[07:06:47]<Lambda_Aurigae> was playing with adjusting the speed to get it to sync up UART comms.
[07:07:02]<Lambda_Aurigae> didn't work real well as the 555 wasn't exactly stable enough for UART comms
[07:10:03]<_ami_> Lambda_Aurigae: you should get those LTC* oscillators. ;)
[07:21:39]<_ami_> anybody uses jekyll for blogging? how to add special characters like ohms or lambda?
[07:23:47]<LeoNerd> TimerBlocks?
[07:23:57]<LeoNerd> Blox? Whatever they call them
[07:29:57]<Lambda_Aurigae> blog
[07:30:17]<LeoNerd>http://www.linear.com/products/timerblox these things
[07:30:21]<Lambda_Aurigae> oh.
[07:30:23]* Lambda_Aurigae shrugs. [07:30:27]<Lambda_Aurigae> too early to think
[07:30:30]<Lambda_Aurigae> _ami_, I don't blog.
[07:30:34]<Lambda_Aurigae> I IRC
[07:30:38]<_ami_> ok :)
[07:30:49]<_ami_> i started bloggin recently
[07:32:33]<Lambda_Aurigae> oh man..today's dilbert rocks!
