I am interested in using the DA14586 with a SPI peripheral at 3 Volts数据表仅勉强提到，您需要使用boost模式拉gpio到3V轨-但它听起来像只有一个上拉电阻。在参考设计中没有显示3V操作的操作参数，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，再次，它不清楚GPIOs可以在3伏特运行。我需要3V推拉SPI。< / 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 >
