 		 #189398 - Breadboards have their place
Responding to: ???'s previous message
Erik Malund said:
with todays fast rise/fall times you are going to get reflections all over the place...

Also:
The contacts themselves are not very reliable;
There's high capacitance between adjacent strips;
They are quite inflexible in the connection arrangement;
The contacts can't securely anchor anything; so it's hard (impossible?) to make "rugged" connections - things do easily get "dislodged"...

Having said all that, breadboards can still be useful; eg,

Prototyping techniques - Breadboard, Breakout boards, Devkit, and matrix board
I'm experimenting with an I2C accelerometer there

should you, by some miracle, get a breadboard to run ANY chip

Well, plenty of people do seem to get microcontrollers running on breadboards...

Your suggestions on starting things with MCUs (8-bit or 32)            01/01/70 00:00      
   what experience do you have?            01/01/70 00:00      
      Starter in electronics, good with programming.            01/01/70 00:00      
   There's more to consider            01/01/70 00:00      
      helpful.            01/01/70 00:00      
   You do realise that 8-bit != 8051 and 32-bit != ARM?            01/01/70 00:00      
      yes I understand.            01/01/70 00:00      
         I think these are the great starting points            01/01/70 00:00      
         Technical or semantics            01/01/70 00:00      
            Thanks for understanding and directions            01/01/70 00:00      
               All required books havee been mentioned            01/01/70 00:00      
               Also buy a multimeter and soldering equipment            01/01/70 00:00      
                  What would be the point of buying a photocopy?!            01/01/70 00:00      
                  what more should I buy?            01/01/70 00:00      
                     would be buying a serial2usb converter to work with laptop            01/01/70 00:00      
                        serial - USB            01/01/70 00:00      
                     Buy an oscilloscope            01/01/70 00:00      
                     Bench PSU            01/01/70 00:00      
                        I've built my own PSU many times             01/01/70 00:00      
                           there is no need for a PSU            01/01/70 00:00      
                              That's very true, and it's convenient, too ...            01/01/70 00:00      
   not at the same time            01/01/70 00:00      
      Yep, shall be starting with 8-bit            01/01/70 00:00      
         you must, to work with the '51 have a copy of 'the bible'            01/01/70 00:00      
            adding some more             01/01/70 00:00      
               And more...            01/01/70 00:00

               My reason for recommending a f12x kit            01/01/70 00:00      
                  Can work for different MCUs too?            01/01/70 00:00      
                     SILabs only            01/01/70 00:00      
                        I'm not so sure that $1000US will cover it            01/01/70 00:00      
                        very valuable, how about compatibility with breadboards?            01/01/70 00:00
