Microcontroller Talk – CRES-ARC
[attachment=43216]
History Of Microcontrollers
Microprocessors came before Microcontrollers
November 1971
Intel introduced the world's first single chip microprocessor, the Intel 4004
April of 1972
First 8-bit microprocessor appeared on the market under a name 8008
April of 1974
8080 became available
Addressed 64Kb of memory, had 75 instructions, and cost $360
MOS Technology - WESCON exhibit ( 1975)
a pivotal event in the history of microprocessors
Announced the 6501 and 6502 at $25 each
What Are Microcontrollers?
Microprocessor – Microcontroller what's the diff?
Microprocessors can not stand alone
instruction decoder, ALU, address/data/ctl. busses, timing logic, (CPU)
Has no capability to interact with the outside world
memory, I/O ports, UARTS, etc. must be added to make it useful
Microcontrollers are small computing systems on a single chip
Central Processing Unit (CPU)
Program memory
Random Access Memory (RAM)
EEPROM - Electrically Erasable Programmable Read Only Memory
A variety of peripheral devices
USARTs, Timer/Counters, ADC, DAC, I/O Ports, CANs, SPIs, etc., etc.
How you can work with microcontrollers
So what’s the catch?
If you are new to software development
You need to think in a new paradigm
Start small and learn the basics first
You can work with microcontrollers on a couple of levels
Walk before you attempt to run
