我有兴趣使用DA14586与SPI外设在3 Volts。数据表仅很少提到您需要使用升压模式将gpio拉到3V轨道-但它听起来只是一个上拉电阻。在参考设计中没有显示3V运行的操作参数,也没有boost模式的例子。我在SDK中找到了GPIO_ConfigurePinPower()和GPIO_POWER_RAIL_3V的定义,但是,同样,它不清楚gpio能否在3伏下运行。SPI需要3V推拉。< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / 3-volts-boost-mode-spi”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > 3伏提高模式SPI < / > < / div > < / div > < / div > < div class =”字段field-name-field-device field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >设备:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " /分类/ / 1492”一词typeof =“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > DA14586 < / > < / div > < / div > < / div >
