Dear all, does somebody have example code, or a IDF component, to use SPI-FRAM? I read the documentation of SPI-PSRAM, with QSPI bus, but that is not what we have. There IS a SPI-FRAM code from Adafruit for Arduino, but it uses the complete Arduino code base and looks difficult to port. The device w...

Dear, there is support for the LCD controller and LVGL on the IDF, with an example https://github.com/espressif/esp-idf/blob/master/examples/peripherals/lcd/rgb_panel/main/rgb_lcd_example_main.c But this page says, that a octal PSRAM is required (or just suggested). For now, we have the ESP32-S3-WRO...

aha, got it. Please forget my last message. I will send the schematic to your PM. Thanks

no, I did not got an email from you. I checked the spam folder, but nothing from you. Would you mind, to send the email again?

can I send you the schematic to your PM? Could you give me your email?

yes, we try to remove R18, and soldered an 10k resistor to GND. We soldered an pin from the I2C GPIO Expander to the reset input on the LAN8720, and switched that pin high after booting first with 1 second, then 10 seconds, but no IP address. We could see with the green LED in the RJ45 connector, th...

Hi ESP_ondrej, after encircling the problem to the LAN8720 - RJ45 connector, we searched more around and found, that many others have similar problems with the LAN8720, where others finally ether gave up with the LAN8720 (https://www.crowdsupply.com/silicognition/wesp32/updates/the-phy-reset-saga, n...

1. I can confirm, that the RJ45 connector is the SA part, with the "ARJP-11A MASA-B-A-EMU2" printed on the RJ45 connector. I measured the resistance and the inductance between the pads of the RJ45 connector, to be sure. I compared the values with a LAN8720 breakout board from waveshare, everything l...

I also tried to bridged the PMOS Q1, to power the LAN8720 together with the ESP32, so that after 200ms after ESP32-EN is high, only the oscillator is enabled and the analog switches connect REFCLOCKO to ESP32-GPIO0. Still no success.

I just wanted to make sure you start initialization of the PHY after the CLK is stable. It seems you do. However, I noticed one other difference between the schematics revisions. You replaced J1 (RJ45 with transformers) to different part number. Eth_LEDGreen- (nINTSEL) is not pulled down as used to...
