14、.1.2 LED 显示电路LED 显示电路如图 5-4 所示。该 LED 为 4 位 8 段，共阳极驱动方式，动态扫描显示，X03为 LED 的位控制；AH 为 LED的数据段。L1AFBHEC图 5-3LED 显示电路5.1.3 键盘矩阵电路键盘为 43（4 行 3 列）的矩阵，电路如图 5-4 所示。键扫时先把其中的一列输出“0”，其他列则设为输且上拉电阻（注意：PA07 上拉 100k），然后再逐行扫描该列，依此类推进行列循环和行循环得到键值。键盘还与 LED 复用。键盘进行键扫时，程序关闭 LED 显示；LED 显示时，为了让键盘不影响 LED 显示，在复用的数据线上串联 2k 电阻，

15、在这一点上，电阻值越大越好，但是 PA07 上拉 100k，如果串联电阻太大，PA03则得不到“0”而键扫失败。PA4R3PA5R1587654321PA6R25PA1R20PA2R19PA3R17PA0R21J4图 5-4键盘矩阵电路 11 :E-29306B3F21AX384GX295CX1107HX011D12EGD68 95 66.1 ()%&W0.=%1#Lq=4-gG1_qj-gGyKL1_qMNAv4-.G LEDj+1LMo-.LYZ./ !pyK1=%1_N?GYRLhGf%1_Ap W.tWZ/WOGYRP3QVRni$SpW./0.NP 6-1 Q)p 12 :E-293
