The main critiria I have is to read the data as fast as possible from the sensors for about 10 seconds, this time might increase (all data received at same frequency).
on the serial monitor - 19200bps
The limit on the speed that you can transmit the data is the baud rate, not how/when the Serial.print() command is called.
The reason you have been suggested to use the ethernet shield is that it would be much faster than USART.
QuoteThe reason you have been suggested to use the ethernet shield is that it would be much faster than USART. Have you verified this? The Server and Client classes bear a close resemblance to the Serial class. I don't think that the ethernet approach will be any faster.
Thanks a lot for your help and advices. I have been trying to test which is my best solution and so far serial seems to be better, I have the following to send: Types Bytes # of each KBytes KBitschar 1 4 7.656 61.248Int 2 1 Float 4 4 Readings = 348/Sec I also was to try to use the EEPROM but I have not been able to get my hands on it, I do know what else to order along with it as its not worth it to pay shipping for few little things that cost less than $2.
