用 Statecharts 实现 Casio F-91W 手表逻辑
Casio F-91W using Statecharts
AI 导读
有人用 Statecharts 为 Casio F-91W 手表建模实现其逻辑。发帖者同时提到，自己刚下单了一款 F-91W 的开源（FOSS）替换机芯，经过几个月的几次校准后精度可达 <15s/yr，且内置加速度计和温度计，并计划为它编写天文和导航应用。
正文
This is funny, I just ordered a FOSS replacement movement for the F91W, which, with a few calibrations spread out over a few months, can achieve an accuracy of <15s/yr (it also has an accelerometer and a thermometer built in). I was planning on writing some astronomy and navigation apps for it
