I've only performed a quick glance at the repo. I don't even have a spare rpi to attempt a compile upon. It looks like SimpleHx711Test isn't threaded so perhaps the quickest way to get to the problem is to build/run that under 'gdb' (perhaps "-g -O0") then issue a backtrace (bt) on it when it terminates? I can't help any more than that I'm afraid. Statistics: Posted by swampdog — Thu May 02, 2024 12:08 pm ..read more

The lgpio linked from hx711 repository was prior to RaspberryPi 5. I uninstalled this old version and installed the new version. I now have a message from the advancedHx711Test, so that is some progress: $ ./advancedhx711test 2 3 1 0 terminate called after throwing an instance of 'std::runtime_error' what(): no samples obtained Aborted Just as another check, on the Pi 5, my data is connected to GPIO 2 (pin 3), clock connected to GPIO3 (pin 5), 5V Power is connected to pin 4 and ground to pin 6. I have also tried connecting the power to the 3.3V at pin 1, same result. I am yet to test the lg ..read more

The only dependency stated is lgpio, I have installed that, it would not build until I did that. I’ll try some calls just using lgpio to confirm it is working. Thanks for the lead. Statistics: Posted by gettingstronger — Wed May 01, 2024 8:07 pm ..read more

All dependencies required by the HX711 library, including lgpio, should be properly installed and configured on your Raspberry Pi. Have you done that? Statistics: Posted by barshatriplee — Wed May 01, 2024 7:44 pm ..read more

'Gordon's wiringPi' which has been deprecated Note that this is not the current wiringPi/wiringPi repository which has taken over from Gordons. Since 2024, GC2 has taken over maintenance of the project, supporting new OS versions as well as current hardware generations.

Hi, I have been spinning my wheels on this and am hoping someone can point me to the right direction. I have a RaspberryPi 5 and am using c++. Having installed https://github.com/endail/hx711 and the prerequisite lgpio (http://abyz.me.uk/lg/lg.zip). I then build all the standard libraries and executables. When I try to run the SimpleHx711Test (and also the Advanced test) it just hangs. I have used wiringPi to test that I am accessing the GPIO ports and can turn a LED on and off. This is the error message I get when running in debug mode: terminate called after throwing an instance of 'std ..read more

Hello friends, i am new to c and i wanted to make an 8 bit dac. I have an r2r dac which i need to control now, it should run at 48khz. I need to execute a quick interrupt function at the said 48khz or different frequencies, the function would prolly be like a gpio_put_masked() function or something.

Hi, I was looking for a c++ library and found lgpio. This is written in C, but I think it's simple to wrap in C++. This is a good library because it is simple, concise, and well written. See this website for details: https://abyz.me.uk/lg/lgpio.html have a nice coding Statistics: Posted by leocata72 — Tue Apr 30, 2024 12:44 pm ..read more
