Re: ESP32 WROOM 32 won't enter serial bootloader mode

Great image for the sequencing of EN and GPIO-0. When does the uploading occur and when do I release EN? The uploading starts via serial data. EN is just really the reset pin. So you can just press it and release it quickly. The important thing here is that IO-0 is held low just a bit longer after ...

Re: Measuring ESP32 Power Consumption

I cannot comment on that specific model, as there are many of them. You can do a few things. #1) Get yourself a meter. Take your USB cable and cut the jacket off somewhere in the middle. Cut the RED wire and put your meter in current mode in series with the 2 red wires. Then you can measure current ...

Re: Fastest clock generated by GPIO

I get 10mhz doing this.

Code: Select all

void app_main()
{
	gpio_pad_select_gpio(BLINK_GPIO);
	gpio_set_direction(BLINK_GPIO, GPIO_MODE_OUTPUT);
	
	
	while (1)
	{
		GPIO.out_w1ts = (1 << BLINK_GPIO);
		GPIO.out_w1tc = (1 << BLINK_GPIO);
	}

Re: stdbool.h

I want to know if stdbool.h is available ?
Forgive my mood, but wouldn't it be easier to simply try #include <stdbool.h> to find out? Rather than to take the time to post the question.

Re: Can I remap the flash UART0 to some other I/O's other than PIN34 and PIN35?

There is an option in menuconfig to change UART0 TX/RX pins. But I am not 100% sure if that is just for the console only.
You can give it a try.

Re: Is it possible to receive GPIO edge type in an interrupt handler (ISR)?

Following the gpio interrupt example, and just to be clear this one here. https://github.com/espressif/esp-idf/blob/master/examples/peripherals/gpio/main/gpio_example_main.c In the following task below from that example, you can add this to it to re-read the pin. static void gpio_task_example(void* ...
