  • RE: LTC2471 I2C No Ack

    the SDA pin on the PIC should be floating after the 8th clock, does your PIC release the control for the SDA pin?

  • LTC2471的I2C接口没有ACK应答。

    LTC2471的接口部分如图所示：

    其中SCL和SDA直接与PIC16F1947单片机的I2C接口的SCL和SDA相连。VDD电压5V。

    用示波器测量SDA和SCL的波形如下：

    可以看到不管是读还是写，最后一位本应由LTC2471将SDA拉低的电平一直为高电平，即无ACK应答。请问有可能是什么地方出了问题？
