#176874 - Avoiding the issue Responding to: ???'s previous message |
Per Westermark said: Ha. That's funny. I wasn't talking about my designs. The problem is when you buy something on the market and they don't use conformal coating, but you void the warranty if you put your own conformal coating. Nonetheless, there are better ways than conformal coating.
Corroding pins? You shoudn't have any corroding pins. If you play in salty environments, you should look at conformant coating where everything is isolated. Justin Fontes said:
Quite frankly, 32-bitters can do the same job an 8-bitter can do, maybe a little more poorly in some applications.
Per Westermark said: Once more - that's a sentence that should read "A specific 32-bitter can get more or less spanked by a specific 8-bitter for a specific task." Obviously you missed that qualifier at the end that said "maybe a little more poorly". However, you failed to mention, once more - that "A specific 8-bitter can get more or less spanked by a specific 32-bitter for a specific task", but I guess that is already assumed because you imply this with a salesman like approach with Per Westermak said:
as mentioned earlier, you can design a 32-bit processor with mnemonic-level support for every 8051 instruction, and able to run any 8051 instruction with the same number of clock cycles. So, why am I working with an 8051/2? I mean you even go on to say that it is economical to misuse power with Per Westermak said: Then you go on to say since cost of a chip isn't proportional to the number of transistors, a processor with two or four times the number of code bytes can be sold at a lower price, if enough customers exists to make it meaningful to produce it in enough volumes using a good enough process. Per Westermark said: You still avoided my original question and gave me that salesman like approach. What is the "suitable market"?
Even if 32-bit processors can compete at lower and lower costs, the market suitable for 8-bit processors will still continue to grow since the total market for microprocessorcontrolled equipment will continue to grow. Per Westermark said: EXACTLY!
Who cares if there is an 8-bit or 32-bit processor in the keyboard? Per Westermark said: Make'em buy that 32-bitter, but in this analogy make only dual UART. I will recommend the 32-bit PIC because everyone likes the ARM or has only worked with ARM.
But how do we make sure that people starts a project with the right processor instead of trying to implement a second UART in software? Per Westermark said: Not one time did I say "great love of ARM chips". Why is it assumed that 32-bitter inherently implies ARM? Isn't that just a bit odd.The reason this thread started to debate ARM chips wasn't because the great love of ARM chips, but because this thread got a number of generalisations claiming that 8-bit processors in general and 8051 chips especially had magic advantages. |
