This article introduces how to draw the schematic diagram of the minimum system protel, the content is very detailed, interested friends can refer to, hope to be helpful to you.
51 single-chip microcomputer minimum system this article uses protel99se this version of software to draw, the latest version of peotel99se and AD for drawing general circuits and PCB is not much different, after all, many schools or units are still using 99se, so we also use this version of software to draw.
1. Newly built project
two。 Create a new schematic:
4. Placing Electrolytic Capacitor 10uF
5. Placement resistance 10K
6. Place a touch button
8. Place this chip capacitor 22p
10. Place 4pin interface a program download interface with STC89C51 52 single-chip microcomputer
twelve。 Place a 10K pull-up group for P0 port pull-up resistor
14. Place self-locking button interface
After the schematic drawing is finished, ERC is required to check that there are no errors before the design OK is counted.
Useful shortcut keys:
Deselect all Xantha
Mirror X to the left and right of the component
Mirror Y up and down the symbol
The schematic content is centered to display VroomF
Schematic magnification pgup
Schematic zooming out pgdn
