Flash迷宫游戏，玩法说明：上下左右键控制小球的移动，争取最短时间内走出迷宫，若时间用完了还没走出来，就输了。+号补血10，被击中失血5，失血用完就死定了。界面不错，开发Flash小游戏的时候，这个可做为参考吧。

说明：  socket 通讯 ABPLC(socket communication using AB PLC)

瑞萨单片机的R8C系列的串口调试硬件和一个闪灯的软件全部工程，瑞萨单片机的资料太少，特别是串口调试的就更少了，更别说这种成套的资料，所以上这个成套的工程给用瑞萨单片机的同胞们，硬件中包括原理图，布好的PCB板，只要连接一个串口1再加上我给出的软件工程绝对就可以串口调试了。(Renesas R8C Family of serial chip debugging hardware and software, a flash of all the works, Renesas MCU little information, especially the serial debug even less, let alone this set of data, so on the sets of project to use Renesas microcontrollers compatriots, including the hardware schematics, PCB board cloth good, as long as the serial port 1 connected together with a given software project I absolutely can debug serial port.)

说明：  1、单向通信 向甲方连续不断地发送变量a的值，未按键，a=0x0f，按键后根据按键确定a值；并将a的值取反从P0口输出，控制D0、D1、D2、D3相应点亮。乙方接收到数据并偶校验正确后，将接收数据取反从P0口输出，控制D0、D1、D2、D3相应点亮。 2、双向通信 甲方连续不断地发送变量a的值，未按键，a=0x0f，按键后根据按键确定a值；乙方未按键不发送，按键后将乙方按键得到的a*16发送；甲乙双方都将发送数据与接收数据相或后再取反，从P0口输出控制D0—D7相应点亮。 3、间隔发送 未按键，甲方不发送数据，按键后甲方每隔50ms连续发送4个字节：0xff、a、a、a。 乙方只在收到甲方数据0xff后的3个数据并验证相同时，才将接收数据*16发送。 甲乙双方都将发送数据与接收数据相或后，从P0口输出控制D0—D7相应点亮。(1. One-way communication The value of variable a is continuously sent to Party A without key, a = 0x0f. After the key is pressed, the value of a is determined according to the key; and the value of a is output from P0 port to control the corresponding lighting of D0, D1, D2 and D3. After receiving the data and checking it correctly, Party B will output the received data from P0 port and control D0, D1, D2 and D3 to light up accordingly. 2. Two-way communication Party A continuously sends the value of variable a without key, a = 0x0f, and determines a value according to the key after the key; Party B does not send the key without key, and sends the a*16 obtained by the key after the key is pressed; Both parties will send the data to or from the receiving data, and then retrieve the data and control D0-D7 from the P0 port to light up accordingly. 3. Interval Sending Without keys, Party A does not send data. After keys, Party A sends 4 bytes continuously every 50 ms: 0xff, a, a.)
