Hi all.
I'm new to NuttX.
I'm not sure if it's no problem me asking some personal question about
NuttX here. (please tell me if better pl
ct than before.
I'll try Tickless OS configuration if I need later.
Thank you very much.

Brennan,
Thank you for your advice.
I checked links you shared and

Alan,
Thank you for sharing the link.
I checked it and I understand CONFIG_USEC_PER_TICK(default 1) is
important when using some functions like usleep().
It won't work well if I try usleep(1) or shorter.
Thank you.

I usually do the following to measure time differences:

uint64_t starttime;
clock_gettime(CLOCK_MONOTONIC, &tp);

omething to do?
I'm using Nucleo-F767ZI board.
Thank you.

Hi Alan,
Thank you for the link. I watched it!
Sorry I forgot to say that I've configured ` I2C Character driver
support ` as well.
However, /dev/i2c1 (or something like this) did not show up.
I'm going to try to register i2c driver.

Hi Yuta,
Yes, you forgot to select the I2C Character driver support.
Please try to follow this tutorial:

per-half driver refering here.
https://github.com/micro-ROS/NuttX/issues/9
In this case, I call mpu9250_register() which I made instead of
i2c_register().
/dev/i2c1 appeared with ls /dev.
However, `i2c dev -b 1 0x03 0x77 ` did not detect any i2c device.

asecally created not for
communicate to general I2C device but created for a specific I2C device
such as MPU9250 and it provides some data with the form which can be
used directly like gyro, accel, temp... not like gx_h, gx_l, gy_h, gy_l,
