What is the minimum width of the wiring in a general PCB processing factory? The 0.2MM and 0.15MM width lines I drew that time were too thin and easy to break....
I used CCS to program Launchpad and everything went smoothly. But because the GPIO was too few, I used an F149 board and an unofficial FET430UIF emulator. When I was programming, it prompted that the ...
What does the vertical line between the brackets [ | ] mean, for example: [ {CONFIG} = 16 THUMBCODE SETL {TRUE} CODE32 | THUMBCODE SETL {FALSE} ] What does this mean? IMPORT |Image$$RO$$Limit| ; End o...
Has anyone in the forum used a voice chip? Not a voice recognition chip, but just a general voice prompt chip. If you think that one has more information or is easier to operate, please recommend it! ...
