HT-nxt-angle - Githubissues

cho934 commented 8 years ago

Hi,

I'm trying to use HT-nxt-angle, but I don't see how to use it using ev3dev-lang-demo or ev3dev-lang-test. Moreover I saw some issues (https://github.com/ev3dev/ev3dev/issues/555)

Could you please help me ?

I don't have the sensor, but it should be possible to use it with the generic sensor class. Something like this should work:

using namespace ev3dev;
sensor angle(INPUT_AUTO, {"ht-nxt-angle"});
assert(angle.connected());

angle.set_mode("ANGLE");
std::cout << angle.value(0) << std::endl;

See HiTechnic NXT Angle Sensor for description of the sensor modes and values.

I'm waiting next release of ev3dev-lang-cpp linked to the last kernel which fix some issues with the NXT angle sensor.

See #5.

I'm trying to not use INPUT_AUTO but specify the port.

using namespace ev3dev; sensor angleRight(INPUT_1, {"ht-nxt-angle"}); sensor angleLeft(INPUT_4, {"ht-nxt-angle"});

And I received always the same error :

terminate called after throwing an instance of 'std::system_error'
  what():  no device connected: Function not implemented

robot@ev3dev:~$ uname -a
Linux ev3dev 4.4.87-22-ev3dev-ev3 #1 PREEMPT Sat Sep 9 14:45:55 CDT 2017 armv5tejl GNU/Linux

What's wrong ?

Succeed ! I replaced INPUT_1 and 4 by sensor angleRight("in1:i2c1", {"ht-nxt-angle"}); sensor angleLeft("in4:i2c1", {"ht-nxt-angle"});

I was not able to get the HiTechnic Accel sensor working as described in cho934's last post, but the following combinations worked for me. Note the addition of ev3-ports: to the sensor address:

auto accel = sensor(INPUT_AUTO, {"ht-nxt-accel"}); // Works
auto accel = sensor("ev3-ports:in1:i2c1", {"ht-nxt-accel"}); // Works
auto accel = sensor("ev3-ports:in1:i2c1"); // Works

whereas the following did not, and left the sensor reporting that it was not connected:

auto accel = sensor("in1:i2c1", {"ht-nxt-accel"}); // DOESN'T work
auto accel = sensor("in1:i2c1"); // DOESN'T work

Thanks for posting this, the port names have probably changed since then
