Hi, I finally got my mindsensors stuff (including a DIST-Nx) and am
still figuring out how to use them with NXC.
It seems we need only two functions:
- a "do a full initialization" one: something like SetSensorLowspeed
(S1) should suffice
- a "I2C command/response" one (using the I2CBytes)
I always get a zero value, no matter what I "send" out on the sensor
port (including correct setup commands).
In fact, after reading documentation of latest NXC version, I came
out with this function:
int readvalue(int c) // doesn't work :-(
{
byte cmd[1], ret[1];
int tot=1;
cmd[0]=c;
I2CBytes(IN_1, cmd, tot, ret);
return ret[0];
}
Calling it for any mindsensors register (0x42, 0x45, etc) always
returns 0.
Where am I wrong?
Thank you!!

To use the DIST-Nx sensor from mindsensors.com you can use the code at this url: (URL) sure you initialize the sensor using the correct type and properly energize it after you configure the port as a lowspeed port.

| Hi, we just bought some sensors from mindsensor.com but I cannot find any info on how to use them with nxc. I have seen that b33 has two new API but there is no "generic" info on how to use them and the mindsensor.com site has no info or sample (...) (17 years ago, 12-Nov-07, to lugnet.robotics.nxt)
