我也是同样的问题,入选
我怎样使用该元件呢?在Ultra Lib中没发现呀。画原理图需要TLC2272
生成封装后,原理图和PCB都是默认在后台打开的,这时要把PCB关掉重开,原理图直接双击就OK拉。
我在转换过程中出现问题如下,然后转换不成功,求解答,谢谢!

I had the same problelm when i tried to convert the RM48L952ZWT.
And I just find out that being a Ultra Librarian version issue.
when I use v5.3.409 I met the "Unexpected symbol : ." error, just now, after i updated to the latest version of v5.3.478, the conversion finished smoothly...
So I compared the two YYYY-MM-DD_hh-mm-ss.txt files, and we can see the differences are the negative numbers: the lateset version use "0-num" instead of "-num" for better compatibility, and we can notice that in the yellow-highlighted line the "-0.xx" was being presented by "-.xx" which I believe was the cause of this error "Unexpected symbol : ."
