ARM7下面读写串口的两种方式：中断方式和查询方式的源代码。详细介绍了ARM7下面读写串口的方式。-ARM7 serial read and write the following two ways: interrupt mode and query the source code. Described in detail ARM7 serial read and write the following way.
SHOW FULL COLUMNS FROM `jrk_downrecords` [ RunTime:0.001437s ]
SELECT `a`.`aid`,`a`.`title`,`a`.`create_time`,`m`.`username` FROM `jrk_downrecords` `a` INNER JOIN `jrk_member` `m` ON `a`.`uid`=`m`.`id` WHERE `a`.`status` = 1 GROUP BY `a`.`aid` ORDER BY `a`.`create_time` DESC LIMIT 10 [ RunTime:0.099303s ]
SHOW FULL COLUMNS FROM `jrk_tagrecords` [ RunTime:0.001301s ]
SELECT * FROM `jrk_tagrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 20 [ RunTime:0.001984s ]
