Hi, I need to transfer a binaryor ASCII file from the PC to the MCS'51 which will be a some distance....Can i use ethernet or CAN controller to do the same? Yes, why not. As well as you can use a lot of other means, wired, wireless, radio-based, optical, (ultra)sonic, cellular, employing your own transceiver, using satellite... Prabal Mehra said: How did you come to this conclusion?
Serial communication over this distance will not be feasible. "Serial" is not synonymous to "RS232". Neither is "asynchronous serial". There are many ways how to extend asynchronous serial, including, but not limited to, RS485/422. There are many valid reasons why to use asynchronous serial when communicating with a '51-class microcontroller. Prabal Mehra said:
A binary file player residing in MCS'51 will convert the file to intel-Hex/requiste format and send it ahead to other devices. OK, this has nothing to do with the MEANS of transmission. Specify your requirements as precisely as you can - distance, required speed, latency, EMI susceptibility, energy consumption, cost, time of development, whatever comes into your mind. Prabal Mehra said:
Secondly, can i remotely (i.e through my PC over LAN etc) send a command to MCS'51 to exectue the program? The '51 can simply wait in a loop until it receives a specific character or sequence of characters. I see no problem in this unless you have other specific requirements (e.g. minimum consumption). Prabal Mehra said:
Thirdly, can MCS'51 inform me of any error occouring over ethernet to my PC? Yes. For example, via the same ethernet, e.g. if the error occurs infrequently. Again, be more specific. You can make no harm writing much when describing your problem. JW |
