Yes, I could switch to a task - that is plan B but requires some refactoring.
I think I can live with the limitations of rmt_tx_start (like, the limited number of rmt items).. and I really want to solve that puzzle
I mean, that tx end callback - it should work shouldn't it ?

Re: Usage of rmt_fill_tx_items and rmt_tx_start
no one ?
whatever I try, its not working with rmt_tx_start.
I could really use some advice

Usage of rmt_fill_tx_items and rmt_tx_start
H ithere, I need to drive some Serial adressable RGB-LEDs (WS2813C). I use the RMT unit for that to do it as fast as possible. Due to the histry of my project it is for both RP2040 and ESP, and I want to keep it as similar as possible. Currently, I use a timer interrupt for setting my LEDs, so that ...

Set Ethernet Link Speed
Hi, I would like to control my lan8720 phy regarding link speed (10 / 100 mbit) to save some power. There ist this method in the mac struct to do that https://docs.espressif.com/projects/esp-idf/en/release-v4.4/esp32/api-reference/network/esp_eth.html#_CPPv4N13esp_eth_mac_s9set_speedE but - how do I...

Re: Ethernet: PICO-V3-02 + Lan8720: some design questions
thanks for your reply. As the RX_ER Signal is not needed, I have one GPIO free now, so i choose the option to use an external 50MHz osciallator and enable them with a GPIO. To have a stable "1" at GPIO0 while startup, there is a 10k pullup (the osciallator can push pull 4mA so this 10k is no problem...

Re: Ethernet: PICO-V3-02 + Lan8720: some design questions
I wanted to add, I use the Pico-V3-02 + LAN8720 because it is a VERY compact solution and I have not much board space.
Thats it how it should look like when layouted in final form factor..

Ethernet: PICO-V3-02 + Lan8720: some design questions
Hi, I made a custom board with the PICO-V3-02 that should have wired Ethernet. I choose Lan8720 for that purpose. While I'm new into using ESP32 I choose to make a evboard with a lot Jumpers so I can learn first and more easily try things out. I already learned about some basic mistakes I made in my...

Re: Get custom board with PICO-V3-02 SoC running
I finally got it running.
I turned out that the missing connection on Pin 19, VDD3P3_RTC was the reason.
I had some other issues with the "one click download" but I could fix that also.
Thank you all for your help! No I can start getting Ethernet working...

Re: Get custom board with PICO-V3-02 SoC running
EN Pin was indeed the first thing I checked. It is high. Yes, I can connect a scope to U0Tx, but I'm sure there will be no output because I think the chip cannot output anything when it consumes no power. - Are you sure you connected the Pico's TxD to the USB-serial RxD and vice versa? I also double...

Re: Get custom board with PICO-V3-02 SoC running
thanks for your hint. You are correct, I didn't connect Pin 19 because I do not need RTC - I thought then it would not be neccessary. Now I see also flash is sourced by that power domain, so I really should connect it. I already connected VDD3P3_RTC pin with some wire to 3v3, unfortunately, It didn'...
