终于解决了，是在stm8s.h这个头文件上没有更改芯片型号，所以在编译的时候虽然通过了，但内部地址乱了，导致这种结果发生

自顶。。。。。。。。。。。。。。。。。。。。。。

正点原子

帮顶....

我觉得有可能是中断向量表那里设置有问题，因为这个一开始是导入库函数的例程，应该没什么代码写错之类的问题

LowTech

我也遇到这个情况，找了半天，终于找到这个帖子，不然不知道哪里出了问题

看了楼主的帖子,不由得精神为之一振,自觉七经八脉为之一畅,七窍倒也开了六窍半,自古英雄出少年,楼主年纪轻轻,就有经天纬地之才,定国安邦之智,古人云,卧龙凤雏得一而安天下,而今,天佑我大中华,沧海桑田5000年,中华神州平地一声雷,飞沙走石,大舞迷天,朦胧中,只见顶天立地一金甲天神立于天地间,这人英雄手持双斧,二目如电,一斧下去,混沌初开,二斧下去,女娲造人,三斧下去,小生倾倒.得此大英雄,实耐之幸也,民之福也,怎不叫人喜极而泣.......古人有少年楼主说为证,少年之楼主如红日初升，其道大光;河出伏流，一泻汪洋;潜龙腾渊，鳞爪飞扬;乳虎啸谷，百兽震惶;鹰隼试翼，风尘吸张;奇花初始，皇皇;干将发硎，有作其芒;天戴其苍，地履其黄;纵有千古，横有八荒;小生对楼主之仰慕如滔滔江水连绵不绝,海枯石烂,天崩地裂,永不变心.

iar 的还是没有头绪 stm8s_it.h和stm8s_it.c不知什么写。有好心人给个例程把
