Bare-metal programming has never been easier!

Then (1987):

Now (2007):
   
  • National Semiconductor NS32032 processor, 6 MHz w/external MMU, FPU, ICU, serial, 32k bytes EPROM, 32k bytes RAM (~$600)
  • Intel Hex boot loader over 9600 baud serial port
  • Homebrew language, compiler, and loader
  • Freescale MCF52221 ColdFire core, 66 MHz w/built-in ICU, GPIO, 8ch A/D, 8ch D/A, USB-on-the-go, timers, serial, 128k bytes flash, 16k bytes RAM ($6)
  • Background Debug Module over secondary USB
  • CodeWarrior C++ Integrated Development Studio

My development environment consists of:

Build a Simple Toaster Oven Temperature Profile Controller (Or Anything Else You Want!)

Build a 2.4GHz Wireless Programmable Doorbell Chime (Or Anything Else You Want!)
