I am a 4th year college student. I had a problem last week, and I couldn't find a solution on the website.
Assumptions
- I want to run the temperature sensor OMRON (D6T-1A-02) demo code on Raspberry Pi
- Ubuntu is installed on Raspberry Pi 4
What I want to achieve
d6t-2jcieev01-raspberrypi I want to run the demo code of
if you succeed (but I can not do right now)
PTAT: 27.2[degC], Temperature: 27.5, 27.3, 27.3, 27.3, 27.2, 27.1, 27.1, 27.2, 27.1, 27.1, 27.3, 27.3, 27.0, 27.2, 27.3, 27.0, [degC]
Problem/Error Message
$ ./d6t-1a
When I did it, the temperature is not output, and the following is output was showed many times.
Failed to open device: Permission denied
PEC check failed: DF(cal)-00(get)
PTAT: 0.0 [degC], Temperature: 0.0, [degC]
Tried
- I completed Soldering so, hardware was completed.
- I followed github procedure written in the official manual (I hope that you click to see the procedure)
·clone
$ unzip d6t-2jcieev01-raspberrypi-master.zip
・make
$ cd d6t-2jcieev01-raspberrypi-master $ make all I was able to do it until
Then I ran
$ ./d6t-1a
and I got the error:
So, I set the I2C speed to 100kHz or less from the boot config.txt as shown on github, but the result is the same.
What can I try next?
