Help your robot do its Math homework

Friday, June 27th, 2014

Ladvien over at LetsMakeRobots writes, "Excellent article on clock-cycle costs of math functions for uCs and processors--as they relate to programming robots." This first point is the single most important one to remember. Integer math is almost always faster than floating point, even on processors that have floating point math...

PL-2303HX bit-bang AVR programmer

Monday, May 26th, 2014

Nerd Ralph writes: I've blogged before about PL-2303HX USB-TTL adapters. In some ways they are even better than the expensive FTDI adapters - for example they work at 6mbps. In conjunction with a cheap Pro Mini clone it's possible to get started with Arduino/AVR programming for $5. For more advanced...
