看了一下，PIC的单片机有片内集成液晶控制器的，AVR没有，可惜了

感觉种类还是少了点

169?

本来在pic和avr中选择过学哪个的，后来杭州买不到18的pic，所以学avr了，16的和avr没法比，而且还有bank，累都累死了，但18大致看了一下比avr强，主要是种类多，pic不象avr把所有的都集成在内，而是集成1个，2个，3个，然后分开卖，感觉这种方法性价比比较高

但既然已经选择了AVR，就会支持它，以上是个人愚见，不对请指出

AVR怎么不产掩膜之类的单片机啊

你拿的169P也太贵了，简直是天价

tsb0574

2$贵吗?要便宜买台湾的片子,但如果体积允许的话还是MCU+HT1621之类的好!!

basten820226

用AVR的I/O直接驱动LCD,只不过外围电路和编程麻烦些

使用169成功开发汽车仪表盘，成本还是比较便宜！

AVR有啊  169吧   不过不多。
