Have a great god used ADS7924 ADC conversion chip?
When I use the I2C read data ADS7924 reply ack is always kept lower release
But reading threshold setting and 00 h registers is that he is to release the
Hope to have used a master, thank you



This is can normal communication, but can't read in a row, otherwise may not release the ack


This is when the read data register does not release the ack

After careful look at the instructions, there should be some configuration register, need to set up devices, to continue down the operation instructions, if not, the original poster can try three increases in bytes after the operation, 40 milliseconds of delay,

CodePudding user response:

Work related registers are set according to the specification, delay also add lead, even if delay 1 s are still not release

CodePudding user response:

As the first figure is put in wrongly, the reply properly is the ack
