Thank you for a detailed description. In order to support fonts other than English, it seems that there is no choice but to sacrifice the advantage of being light and fast. I am still satisfied enough now. I have two questions. 1. I'm using an ssd1306 0.96" OLED i2c panel. Will the VU meter not appear in this environment? (Limit screen size and resolution?) RPi3B+, picoreplayer 6.1.0 I used the command as below. gomonitor rn -o3 -f11 Use -v option to squeezlite and 1 option to use shared memory 2. The temperature unit of the weather is displayed in Fahrenheit. I can't find a way to change it to Celsius. 31561 +-------------------------------------------------------------------+ |Filename: 2020-09-16 11.35.23.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=31561| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ blackbird's Profile: http://forums.slimdevices.com/member.php?userid=70562 View this thread: http://forums.slimdevices.com/showthread.php?t=111790 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
