Hello, At Power ON Condition, XMEGA Keep the SS pin of ESP32 high and Other Slave Low. I have checked the MISO pin on CRO individually, ESP MISO is always low (SS is HIGH) and other Slave device have Data on it(SS is LOW). When I make common MISO by putting Resistors, At power ON, there is Data on M...

Hello, In our current project, we have Micro controller XMEGA as a SPI Master and 5 SPI Slave Devices connected. Out of 5, we are using ESP32-WROOM-32U SPI as a slave but the MISO pin of ESP32(GPIO33) affect the functionality of another slave device and break down the communication between Master Mi...

Hello, I am using ESP32-WROOM-32U module. Here I want to use JTAG pin either GPIO or JTAG and for that I am IO34(Pin#6) as a Input pin for selection mode. IO34(Pin#6) will detect either 1 or 0. If it will detect 0 then IO12-15 are work as a GPIO and 1 then work as JTAG. This pins are handled by Mux\...

Hello,

Thank you very much for the Answer.

What is the value of Pull up resistor on GPIO0 using as EMAC_TX_CLK.

Have you any reference schematic?

Please provide if you have.

Hello,

I am using RMII mode in ESP32-WROOM-32U using KSZ8041RNL.
According to KSZ8041RNL datasheet, it will give 50MHz clock output which will given to MAC (ESP32-WROOM-32U).
So here how i will connect to MAC (Pin#)?
