Hello,

I use the UART Echo example with ESP IDF 4.0.1 and it looks like the software isn´t receiving anything when I use UART 1.


#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "driver/uart.h"
#include "driver/gpio.h"
#include "sdkconfig.h"

Hi,

I want to dive a little bit deeper into the esp-idf to program the ULP of the ESP32. As a first start I try to implement a simple blinking example for the ULP, but I struggle with the default analog configuration of the RTC pins.

I have checked the Technical Reference Manual ( https://www ...

Hello,

I use a custom programming board to program an ESP32 with a secure bootloader


esptool.py '--port', 'COM14', '--baud', '921600', 'write_flash', '--flash_mode', 'dio', '--flash_freq', '40m', '--flash_size', 'detect', '0x10000', 'hello-world_secure.bin', '0x8000', 'partitions.bin', '0x1000 ...

Hi,

2) I have flashed the application onto the ESP32

Hi,

I try to use the JTAG debugger on my ESP-WROVER-KIT-VE in an Arduino and the esp-idf environment with Visual Studio Code and PlatformIO. I wrote a small program to test the debugger:

static void applicationTask(void* p_Parameter)
{
setup();
while(true)
{

TIMERG0.wdt_wprotect = TIMG_WDT ...

Hello,

I try to capture two images with different light scenarios by using the ESP32 camera driver. My code looks like the following example:


camera_config_t CameraConfig;
...
CameraConfig.fb_count = 2;
esp_camera_init(&CameraConfig);

Image1 = esp_camera_fb_get();
...
Image2 = esp_camera_fb_get ...

Hello,

I want to use the BluFi demo in combination with the Arduino framework, so I modify the code:


#include "blufi_demo.h"

static uint8_t UUID[32] = {
/* LSB <--------------------------------------------------------------------------------> MSB */
//first uuid, 16bit, [12],[13] is the value ...
