将驱动库固化到ROM当中是一项创新举措

<big><br />驱动库函数固化在ROM当中,好处有:<br /><br />1.&nbsp;不会占用用户的任何Flash资源<br /><br />2.&nbsp;最大限度提高代码密度<br /><br />3.&nbsp;加快程序执行速度<br /><br />4.&nbsp;这是Luminary免费提供的,不存在版权问题(royalty-free)<br /><br />5.&nbsp;固化的驱动库同时也是bootloader(即ISP下载),提供UART、I2C、SSI等多种接口<br /></big><br /><br />(zlgmcu_wdx)

好呀

以前出的各种型号的,在以后生产中驱动库函数是否也做到内部去呢?
zlgarm 发表于 2008-4-17 16:59 | 显示全部楼层

已经固化好驱动库!

&nbsp;&nbsp;&nbsp;&nbsp;出厂前驱动库函数已被固化到ROM中,用户再也不需在Flash代码中嵌入驱动库函数,只需调用ROM的函数就可以了。<br /><br /><br />(zlgarm_zsg)<br /><br />

崭新冬眠模块,超低功耗,一颗电池可维持供电长达3年

<big><br />冬眠模块(hibernation&nbsp;module)包含有一个32位RTC定时器、256B非易失性存储器。可通过RTC匹配、外部管脚中断或者电池电量低事件来唤醒。采用一颗标准的CR2032手表电池可以提供长达3年的电力。<br /></big><br /><br />(zlgmcu_wdx)

OTG, Goood. 虽然是可怜的 FS

不错哦<br /><br />价格&nbsp;低于&nbsp;$6&nbsp;&nbsp;就好。<br /><br />USD&nbsp;2.79&nbsp;???&nbsp;OTG?<br /><br />软件 是否 有  足够的 例子?<br />仅 μC/USB&nbsp;Host&nbsp;?<br /><br />

中断声明?

那是不是startup.c都可以不加了?&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

有点意思,不知道价格什么样?

确实有可能不需要startup.c了

TCP也可固化啊

象MAXIM&nbsp;的DS80C400&nbsp;TCP/IP&nbsp;V4/V6都已经固化了。Luminary&nbsp;也可参考一下啊,DS80C400&nbsp;是增强80C51的,速度有些慢。但思路不错,听说销量还可以,当然它在五年前就有了。

TCP/IP固化进去不太好吧,

以太网的驱动应该有,不过TCP/IP协议栈如果固化进去了,不稳定怎么办?如果要稳定的协议栈一定贵啊。

貌似不贵

价格:2.79美元<br />貌似不贵,可以接受<br />应该是个好东西

LM做得不错

固化的是ROM,成本比Flash低,以此方式提供固化Lib确实高性价比。

到时候大概会是什么价格(RMB)

正在为chameleon考虑更加低成本,高性能的芯片(满足资源要求的前提下)。
