Other makers offer different processors with different abilities, memory, pin count, etc.ĭoes your application require a faster, larger memory chip, or are you ultimately looking for the lowest cost chip that can get the job done ? The Cortex M4 is a bit more like a Ferrari to the Arduino 328 chip.Īs a note, ATMEL is but one chip maker, their software is designed for use with their chips. Often the parts selection is the lowest possible device. What is your application that cannot work on An Arduino ? What application are you having problems with that you need a separate debugger ?
not every chip supports debugging on separate pins and as you know, not every software offers it either.īut as in the first concept, no one but the designer really cares. I will offer that since you have no clue what software is used in your toaster, your coffee maker, alarm clock or toothbrush would mean that the user does not care. If you need to use CAN (WiFi, etc) bus, the cost for a micro that has that is compared to using additional parts, taking more space, and it may or may not cost less. If you never need to use an analog input, save a few pennies and get a micro that costs less but does not have that The only need to switch to a different software is to get some result that cannot be achieved with the current software.įunctions, space and cost are usually the motivating factors.
and you use parts that in the desired price range. If your Arduino IDE produces code that works. If the bloated program requires a large chip, but a sleek program can use a smaller chip, then use the sleek program. the smallest space, the lowest parts costs are often the driving factor.
