ULP Loop

[Eric_9999]

Can somebody help me how to make a 'for loop' in Arduino ULP
This is my code,

Code: Select all

#include "esp32/ulp.h"
#include "driver/rtc_io.h"
#include "UlpDebug.h"

void ULP_RUN();

void setup() {
	Serial.begin(115200);
	delay(1500);
	Serial.println("GO");

	ULP_RUN();

	esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_PERIPH, ESP_PD_OPTION_ON);
	esp_deep_sleep(30000000);
}

void loop() {
}

void ULP_RUN() {

	RTC_SLOW_MEM[12] = 0;

	const ulp_  ulp_test[] = {

	I_WR_REG(RTC_GPIO_OUT_REG, 26, 27, 1),    // GPIO 2 --> HIGH

[b]LOOP HERE...
..for x = 1000
I_DELAY(15000), /*0,001875 sec*/
...end
[/b]

	I_WR_REG(RTC_GPIO_OUT_REG, 26, 27, 0),    // GPIO 2 --> LOW
	
	I_HALT()

	rtc_gpio_init(GPIO_NUM_2);
	rtc_gpio_set_direction(GPIO_NUM_2, RTC_GPIO_MODE_OUTPUT_ONLY);
	rtc_gpio_set_level(GPIO_NUM_2, 0);

	size_t size = sizeof(ulp_test) / sizeof(ulp_);
	ulp_process_macros_and_load(0, ulp_test, &size);
	ulp_run(0);
}
