Never get DRDY #4

Closed philgrim2 closed 3 years ago

philgrim2 commented 7 years ago

Using the breakout board with an Uno R3. Put in some Serial.println settings to try to discover why I don't get results. DRDY never goes low. I have two boards, same results with both.

Could you please attach the connection setup?

Same issue here. Any updates?

@gcmike Sorry for the inconvenience caused, Please provide us the additional details/share the screenshots.

Currently we are using MSP430F5510 to communicate with this. The spi setting seems to be working, but the DRDY pin is kept high. The GPIO pins seems not specifically setup inside the program, and the default would be input? Should they be pulled low with resistors? Another question, is the higher grade capacitors needed?

@gcmike thanks for sharing, Couple of things:

If your msp430xxx is 3.3V tolerable change the jumper setting on the breakout to 3.3V. By default it will be 5V.
No additional pulldown is required since there is a on board level converter. Ensure START and PWDN/RESET are pulled high.
