I am using Qt Created IDE in Windows. I am a beginner however after linked the library file (LIBS += -L"$$_PRO_FILE_PWD_/i386/" -lCH341DLL) in .pro file and try to build it gives me errors like "UCHAR does not name a type, did you mean QCHAR_H?", "mPCH341_INT_ROUTINE was not declared in this scope", "BOOL does not name a type" and many other similar errors. I tried with MSVC2019 64bit, 32bit same issue. Any suggestion what I may be doing wrong?

That was a preliminary design idea. In the final design, one can simply remove the 82 ohm resistor and drive the transistor with PWM to achieve the same results. I don't think noise will cause any issues to the sensor but that's something I have to check.Corneliushttps://www.blogger.com/profile/01946326524810788501noreply@blogger.comtag:blogger.com,1999:blog-468994113812845572.post-58198291467122927442024-02-25T07:18:40.191+02:002024-02-25T07:18:40.191+02:00I am running Ubuntu Budgie and I get No PulseAudio...I am running Ubuntu Budgie and I get No PulseAudio daemon running, or not running as session daemon.<br />How can I fix this?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-468994113812845572.post-72714395631514766482024-02-24T15:45:03.876+02:002024-02-24T15:45:03.876+02:00Hello, nice design.
