Hello everyone,

does anyone knows/have an example code for using DMA transactions on ESP32 ethernet hardware ? I could not find any example online...

Thank you !

Hello ESP_Sprite, I also suspected the GPIO interrupt issue which you described in your last post. I will check again if the tasks are pinned correctly and will post any issues here. At this stage I want to ask if "esp_intr_alloc(...)" is capable of registering a Level-5 interrupt? Means, can I repl...

Hello ESP_Sprite, I have just changed the GPIO interrupt configuration in gpio_reset_pin(emac->int_gpio_num); gpio_pad_select_gpio(emac->int_gpio_num); gpio_set_direction(emac->int_gpio_num, GPIO_MODE_INPUT); gpio_set_pull_mode(emac->int_gpio_num, GPIO_PULLUP_ONLY); gpio_set_intr_type(emac->int_gpio...

Hello ESP_Sprite, sorry for the unclear wording in the initial post ;) Unfortunately, executing ADC interrupt configuration after Ethernet Initialization did not help. Further, the Core IDs got interchanged, which means that ethernet ISR was running on Core 1 instead of Core 0. I think one calls thi...

Hello all, @bienvenu: Hello ! Thank for your answer. I thought you just left this community... I pm'ed you several months ago, but you never returned ;) Can you tell me please what module you exactly used as RMII PHY (LAN7820A) ?? Maybe provide a link ? @ESP_Sprite: To test if the ADC interrupts are...

Hello ESP_Sprite, Sajeel and me working together on that issue. Please don’t wonder why I am posting here the minimal code. Before starting, I want to make clear, that we use an Level-5 interrupt to “catch” the “DATAREADY” interrupt of an external ADC as fast as possible. The Level-5 interrupt handl...

Hello all, I am driving on HSPI an external high-speed ADC and on VSPI the external ENC28J60. After some debugging, I figured out, that when "esp_eth_driver_install" is executed, the HSPI seems not working anymore. After analyzing "esp_eth_driver_install" I figured out, that within this function the...

Hello everybody,

I hope you all doing fine during the covid-19 time!

Does anyone have and can share a simple library for the Wavelet Packet Transformation (WPT) ?! As far as I know the DSP library of ESP-IDF does not include the WPT.

Thank you !

Best regards and stay health !

Hey, without seeing any code: As far as I know and understand the WiFi driver is independent from the TCP/IP layer, meaning connecting to an access point has nothing to do with TCP/IP at first. After your connection is established, then your access point is assigning your device (ESP32) an IP addres...

Hello,

can you maybe tell more about your motivation for doing that ? Maybe other readers can find an alternative solution for you ?
