MCC172 examples C data_logger #48

I can execute the example C "logger". I output "10Hz" "sine wave" through a signal generator. I can't see the X-axis units. But I can see "logger.c line179 freq_val value" in the console. I print it on the console.

Please tell me what I might be doing wrong. Thank you

Screenshot from 2022-11-14 08-23-34 I'm not seeing that on my Raspberry Pi 4. My guess is you have something not installed or installed wrong for this example. In particular that graph object, the GTKDatabox. I recommend you uninstall your existing daqhats installation, download and install a fresh copy of the daqhats software, review and run the instructions found in the readme.md found in the folder for that example.

OK! I using Raspberry Pi3 Model B OS: Pi OS 64bit I reinstalled all programs. When I install GTKDatabox. This error occurs on the terminal. But I can't solve it. I would like to ask what is your environment? I want to build the same environment as yours on my board. thanks for your help image

I've run this on RPi 3b 32 bit, and RPi 4B 32 and 64 bit.

HI @jeffreyg3 It's really a system environment problem. I changed the board from 64bit to 32bit to solve this problem. Thanks for your help mcc172_logger

This has been fixed for the 64-bit OS.
