I am currently using a picaxe 28x1 for a project. It has three devices that communicate using rs232. I have bought a diecimila but have not tried to use it yet but I have found the speed of the picaxe for this project a bit of a burdon, for this project atleast. Before I try to swap out the picaxe for the arduino I would like to clarify a few things.
- What is the maximum baud rate and is the serial on the arduino a true serial. Can you have multiple devices.
- The picaxe has a 127 byte scratchpad does the arduino have a similar facility.
- Is it quite easy to make a circuit board for arduino I.e easily found components to support arduino on board.
- Is to possible to deploy new firmware with out having to use the program editor such as just a hex or bin file.
