#101434 - integrated or standalone Responding to: ???'s previous message |
You have basically 2 options:
- get a '51 with USB integrated - get a standard '51 and an USB-to-some-other-bus convertor chip. The second choice is probably more expensive but faster way to go. Usually you don't need to bother with the USB details at all. In the simplest form, you can go and buy a USB-RS232 converter "cable", so you have the familiar RS232 at the '51 end. The next move would be to get rid of the double RS232-5V conversion and put the USB chip on one board with the '51. I would recommend the FTDI chips. They can go above 1Mbaud which I think is sufficent for the vast majority of '51 applications. On the PC side, you still see a COM port. If this would not be sufficient, the next move could be the FTDI245 chip, which talks parallel, up to 1MByte/s (which is around the maximu what you can get from a full-speed USB device). Still looks like a COM port on the PC. For the first choice, you would need to choose first - Cypress, TI, Atmel comes into mind, maybe others will suggest more - then learn how to use it... A longer way to go. Jan Waclawek |
