Ethernet DMA Example

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 !

Re: Using Multiple interrupts in esp32

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 ...

Re: Using Multiple interrupts in esp32

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 ...

Re: Using Multiple interrupts in esp32

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 ...

Re: Using Multiple interrupts in esp32

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 ...

Re: Using Multiple interrupts in esp32

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 ...

HSPI and VSPI simultaneously issue

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 ...

Wavelet Packet Transformation ?!

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 !

Re: conntecting to Wifi using static IP

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 ...

Re: SPI Rx abort

Hello,

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