The ULP is a low-power coprocessor (Ultra Low Power) integrated into the ESP32 MCU. This sketch just blinks the * on board LED on for x microseconds and OFF x microseconds using the ulp. , if it uses the label's byte address as needed here, or if it 'helpfully' divides the byte address by 4, which would be wrong for this case. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. This instruction gets 'x' as an argument, and sets up the wake up time to the value of SENS_ULP_CP_SLEEP_CYCx_REG. Apr 23, 2021 · I'm trying to communicate with a sensor using the 1-Wire protocol from the ULP-RISC-V coprocessor on the ESP32-S2.
