- 實(shí)現(xiàn)漢字向上滾動顯示
- P5用于譯碼器LM138實(shí)現(xiàn)靜態(tài)掃描（低四位驅(qū)動），P4用于LM595串行轉(zhuǎn)并行。
- LM595采用級聯(lián)，可輸入多個(gè)字節(jié)。DS為LM595的數(shù)據(jù)口，SH上升沿保存串口數(shù)據(jù)
- ，ST上升沿推DS數(shù)據(jù)到LM595輸出端，ST下降沿將輸出端鎖存。
- 運(yùn)行時(shí)顯示小組標(biāo)志和“黑客電子小組”向上滾動輸出。
- 硬件資源：
- MSP430F155、LM595(兩個(gè))、LM138(兩個(gè))、8*8LED點(diǎn)陣（四個(gè)）
