Armando	46e71e43ba	fix(adc): rename ADC_ATTEN_DB_11 to ADC_ATTEN_DB_12 ... By design, it's 12 dB. There're errors among chips, so the actual attenuation will be 11dB more or less	2023-11-08 03:44:43 +00:00
Armando	eab3534c90	adc: no longer support adc2 oneshot mode on esp32c3 ... Due to HW limitation, we don't support this anymore. On c3, ADC2 under oneshot mode is not stable. However, you can enable CONFIG_ADC_ONESHOT_FORCE_USE_ADC2_ON_C3 to force use ADC2.
