Hi,
I am currently working on the wireless heart rate monitor reference design as given by TIDA 0096.
The problems are,
1) When I power the circuit with 3.3 volt supply, the ads1293 reference voltage(Vref) is showing only 0.5 v. But according to the data sheet, the Vref should be 2.4V by default, since the register 0x11 is 0x0 at power up.
2) Also I am not able to read the register values or set the registers of ads1293 through SPI bus.
Please help me in resolving these issues.
When I checked the supply voltage for Ads1293, it is displaying proper 3.3v.
