Hi Matheus, Thanks for your post! Probe the power pins (AVDD,DVDD) to see if power is correctly reaching the part. If POWER SUPPLY IN and POWER SUPPLY GND are short circuited, your board may very well be damaged. To check to see if the ADS1299 is damaged, probe the VCAP voltages with respect to AVSS: VCAP1: AVSS + 1.2V VCAP2: (AVDD+AVSS)/2 VCAP3: AVDD + 1.9V If the VCAP voltages look ok, then I would recommend uninstalling all software, including the drivers, then re-install following these directions: e2e.ti.com/.../656505 Please consult the ADS1299 User's Guide for how to properly provide external power to the board.
