(...) Hi, halfduplex is not the problem when connecting the NXT to an external MCU. My problem is the bitrate of 921,6 kbits/s. Simple cheap MCU like ATMega didn't support this bitrate (as far as I know). To add an external devices (e.g MCU+SD-Card (...)

(...) Hi John. I must have misunderstood something I was told a while back which went along the lines of "there isn't enough time to implement support for this feature". Perhaps there was some time after all ;) Do you know how large the OutBuf and (...) (19 years ago, 9-Apr-07, to lugnet.robotics.nxt)

(...) Yes. RobotC already supports an optional "fast" mode that is five times faster transmission when reading a single byte. For reading multiple bytes from an I2C device, RobotC is about 15 times faster than the NXT-G firmware. There are a couple (...) (19 years ago, 9-Apr-07, to lugnet.robotics.nxt)

(...) Do you think it is possible to read/write binary and ascii data to this device or is there a special protocol neccessary ? What about bitrate of EIA-485 device ? Is it possible to adjust bitrate to anything more usable (9600, 38400, 115200) ? (...) (19 years ago, 9-Apr-07, to lugnet.robotics.nxt)
