Part Number: ADS1118 I am facing a very unique problem with ADS1118 . I am reading single differential sensor data in continuous conversion mode with the ADS1118 between A0 and A1. At the time of development I ordered 3 ADS1118 breakout boards and made them to communicate with my controller STM32F407VGT6 via SPI . Those 3 all had markings 71 marked on them . Those breakout worked perfectly fine with my controller. But recently i have ordered 6 more breakout boards for the ADS1118 from different sellers and all have marking 79 on them . None of the board correctly communicates with my controller with exact same code which still makes one of the leftover older breakout with 71 marking on it to work correctly. What i have noticed is- 1) The older one with 71 marking on them update the Configuration register with correct values which i write to it and hence give correct ADC outputs 2) All these newer ones with 79 marking do not update the configuration register with the data i want to write into them but write garbage values into it and hence do not give proper output. I am in a urgent need of help in above regard because the only difference i can see among the older and newer breakouts is this marking of 71 and 79 that why i am referring them here. And my costumer is after my life as i am not able to deliver him the end product on time. Please if someone has knowledge in this regard please help. Thanks in advance.
