Re: [info] ESP32-EVB board for IoT with Ethernet 100Mb interface..

Now I would like to connect the ESP32 direct to my PC via the Ethernet interface, but I am not sure if it is possible at the moment. I am asking becasue what I see now is all related to Wifi, example the DHCP stop does not work for ethernet .. hi juan, if you connect the ESP32 direct to your PC wit...

Re: About the CAN controller.

Hi guys. Just to confirm: Wroom32 GPIO5 <---------> CAN TXD (D) Wroom32 GPIO4 <---------> CAN RXD (R) Is this correct? In relation to the nature of the question, first, how you want drive CAN on ESP32? MCP2551 , TJA1051 , SN65HVD233 5V / 3.7V / 3.3V cause ESP32 is 3.3V - be sure your Receive Lines ...

Re: How to Visually Tell New from Old Silicon?

The getChipRevision function in Arduino has a bug, by the way, as it has "&& EFUSE_RD_CHIP_VER_RESERVE_V" instead of "& EFUSE_RD_CHIP_VER_RESERVE_V". .... btw: LoL https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/Esp.cpp#L120 uint8_t EspClass::getCh...

Re: How to Visually Tell New from Old Silicon?

hi rudi ;-) the ESP32-D0WDQ6 sample came from distribution as silicon version 1 and I've replaced into a ESP-WROOM-32 module. the piece marking says 012017 , PC3W29. Apparently the manufacturing week doesn't ensure being V1 but, from ESP_igrr words, prior to that there were some pieces manufactured...

Re: How to Visually Tell New from Old Silicon?

rudi ;-) , is that information from EFUSES fully trustable? The piece I have was supposed to be silicon version 1 and I'm reading 0. if you not get this "sample" piece explicitly from espressif, then i think you only have Rev 0 cause the silicon Rev 1 is "just in time to go on" ...

Re: Pin differences for embedded flash

good catch robin, txs, @espressif From the ESP32 series of chips specified in this document, ESP32-D2WD has 16 Mbits of embedded flash, con- nected via pins GPIO16, GPIO17, SD_CMD, SD_CLK, SD_DATA_0 and SD_DATA_1. The other chips in the ESP32 series have no embedded flash. this mean, GPIO16 can not ...
