It is called POA30R. Datasheet here https://drive.google.com/file/d/1wYMk00ibXZ6w4rteR4x_wsQMKeaZSpQT/view?usp=sharing 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 just GPI...

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/ahmedwahda...

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 hardwar...

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 overf...

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 exactly...

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 UART_N...

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: https...

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 same...
