I experienced this before calibration, and it's still happening after calibration. It's possible the screen just stops responding, because I can hear the fan come on and off when I press the power button. I have a 36v 11A supply to back this unit, I calibrated it and told it the max amperage it could drive was 10A, this is the resulting calibration report.

Calibration Report: A_ADC_K = 4.377185344696045 A_ADC_C = -260.4835205078125 A_DAC_K = 0.25430262088775635 A_DAC_C = 263.3804931640625 V_ADC_K = 8.133505821228027 V_ADC_C = -109.9773178100586 V_DAC_K = 0.1118573322892189 V_DAC_C = 8.37867546081543 VIN_ADC_K = 16.66666603088379 VIN_ADC_C = 118.33333587646484 VIN_ADC = 2305 VOUT_ADC = 14 IOUT_ADC = 0 IOUT_DAC = 0 VOUT_DAC = 0

I have attached the files grabbed before I changed the firmware in case that might help.

hi, maybe it's related to #203

I lopped out the ifdef around:

ifdef DPS5015

define TFT_CSN_PORT GPIOA

define TFT_CSN_PIN GPIO8

endif

and recompiled. I had some issues and had to rewipe the whole unit and reflash from scratch, but it seems to work now. I'll keep testing

seems stable now, just treat the DPS3215 like a DPS5015
