Device appears well constructed, but there is ZERO application information, not even on the Chinese website. TI has an excellent document on the ADS1256 and how it works, recommendations for construction, and a complete set of tables of instructions and how they need to work on SPI 4 wire interface. My problem is that despite regularly running SPI devices, I'm unable to get anything but 0x00 out of the bytes in the registers of the device. With the TI device one writes a read register command, plus the number of registers to read and expects the current values of the registers to be returns. Bupkis, nada, all zero values for the seven registers. It should have returned readings with all the default values upon boot up. Perhaps, I've been unlucky. It's happened before with Chinese electronic modules, 3 out of 4 died within a day of power up. Nonetheless, most of the vendors produce quality products.My advice is be careful, buy where the vendor gives more than a data sheet as support.
