Could I interface this image sensor with ESP-IDF (ESP32S3)?


I will use an example from this repository.
I'm confused about what pins can I use from ESP32S3.
It is fine with ...

I found solution.
I added modify policy of AWS IOT device like this link.
https://docs.aws.amazon.com/ko_kr/freer ... ertos.html


But after executing device and doing OTA job, it is nothing happend.

I'm implementing AWS IoT OTA to ESP32-S3.

I built an example from esp-aws-iot ( https://github.com/espressif/esp-aws-iot/tree/master/examples/ota/ota_mqtt
and set configuration for wifi and aws endpoint, certs.

I set policy and role for OTA.
I reference this page ( https://gist.github.com ...

I would like to use Modbus TCP and AWS IoT at the same time.
I implement all features for both comminications well.
However Modbus TCP and ethernet cannot connect from Master after Wi-Fi connected to use AWS IoT.
I don't understand why it is not working.
Is there any restrict of software and ...

Stack overflow is probably caused by error printing. You can try to increase `rx_task_stack_size` of `eth_mac_config_t`config structure. However, it would worth investigating why you got `spi transmit failed` error.


Thanks for your reply.

I changed rx_task_stack_size and I could not see stack ...

I use ethernet by using W5500 and ESP-IDF driver and implement MODBUS TCP communication.
After 30~40min, I could see this stack overflow error.
Also I use display illi9341 and DAC to same SPI bus.
How can I solve this problem?
Some people say that malfunction of W5500. However I don not know ...

I change code like this and error is gone
const uart_config_t uart_config = {
.baud_rate = 115200,
.data_bits = UART_DATA_8_BITS,
.parity = UART_PARITY_DISABLE,
.stop_bits = UART_STOP_BITS_1,
.flow_ctrl = UART_HW_FLOWCTRL_DISABLE,
.source_clk = UART_SCLK_DEFAULT,
};

Hello
My code was working well. But I could see this error after changing my board and IDF version as 5.0 from 4.4

Is it hardware problem or I have to change pin or uart configuration in my code?

My code:


#define LPC_TXD_PIN (GPIO_NUM_17)
#define LPC_RXD_PIN (GPIO_NUM_18)
#define LPC_UART_NUM ...

I'm testing Modubs RTU example.
Whenever I tried to read Input Register value.
I can see 02 Illegal Data Address.

I'm using Modbus Poll window program to check Modbus communication.
other functions are working well such as Coils, Discrete Input, Holding Registers.

I use code from example here ...

I'm developing a data acquisition device.

I'm using WIFI STA mode for uploading data to AWS IOT
and I will implement MODBUS TCP/IP for industry automation like PLC.
For connect MODBUS TCP/IP, I will use WIFI Module. It will be connected to ESP32 by SPI

Can my device use two communication at the ...
