Hi,
I am using ESP-EYE, i have installed ESP-WHO on system as per instruction, i tried as is example project of ESP WHO to capture image.
Now i have to add ESP Http client to esp who example project to i can notify to cloud server. i would like to know how i can add http client in this project

HI, I am trying to interface ESP32 with Phy controller DP83848, i am using the Olimex reference Hardware Link there is one change in hardware, instead of using BD5230G to control OSC, i am controlling it from GPIO pin of ESP32, on Power up it is LOW for particular period. The problem is i dont get a...

am also looking for the same, am trying separate uart interrupt there am little confuse about the interrupt API's ,can u share that code.
thanks

sorry for late reply

here is the code on github
https://github.com/theElementZero/ESP32 ... nterrupt.c

i got the solution,

i have to use ESP_ERROR_CHECK(uart_isr_free(EX_UART_NUM)); before uart_isr_register, as install driver also initialise interrupt subroutine.

Thank for help

Im not sure you can use UART0, its serial port used to debug. Like kolban said its better to use this line that way: static uart_isr_handle_t handle_console; .... ESP_ERROR_CHECK(uart_isr_register(EX_UART_NUM,uart_intr_handle, NULL, ESP_INTR_FLAG_LOWMED, &handle_console)); or you have to initialize...

Just a guess, but if I am reading your code correctly, we have: uart_isr_handle_t *handle_console; ... uart_isr_register(EX_UART_NUM,uart_intr_handle, NULL, ESP_INTR_FLAG_LOWMED, handle_console) I can't help wondering if the following might not be the correct pattern: uart_isr_handle_t handle_conso...

In your code snippet, I think you are saying that this call is failing: uart_isr_register(EX_UART_NUM,uart_intr_handle, NULL, ESP_INTR_FLAG_LOWMED, handle_console); In the snippet, you didn't show what the value of EX_UART_NUM was nor did we see the definition of "handle_console". Sorry for inconve...

I would first recommend that you rework your code to check the return codes from all the ESP32 functions and validate that they are all returning ESP_OK and, if not, what code they are returning. Thank your for reply and your time, uart_isr_register, returns ESP_FAIL, error code is 0x105 ESP_ERROR_...

Hi, i am trying to work with UART on esp32, using esp-idf. i modified UART event sample code so that i can register UART IRQ routine and receive data directly, below is modified code, void app_main() { esp_log_level_set(TAG, ESP_LOG_INFO); /* Configure parameters of an UART driver, * communication p...
