Re: EMAC receive not working

rudi,搞定gpio的ext_clk或者gpio16的clk_out,论坛里面发个帖子,emac就差这么点了 hi www220, just in time with LAN8720 there is a 50 MHz clk on board. on tlk110 eval board from TI there is a 25 MHz on Board ( MII ) to use the tlk110 board with RMII we must change the onboard clk to 50 MHz i would really much more work on GP...

Re: ESP IDF and C++ linker problem with xRingbufferReceive

Hello Rudi, thanks for testing. But if I see it right you have tested it with a .c file. My problem only occurs when I use the .cpp ending. If I don't have the extern "C" before the app_main() it don't compiles. (I think the reason is that this function is called by a C function.) Unfortunately it ...

Re: ESP-WROOM-32 AT commands firmware

I tried to follow the steps to flash the ESP32-AT but seem doesn't work. .. I am quite confuse on the UART1 Tx and Rx pin number. Which pin number does it refer to? Is it the UART1 pin number on the ESP32 chipset? Is there any full instruction on flashing the ESP32-AT and able to work? hi it work's...

Re: ESP IDF and C++ linker problem with xRingbufferReceive

Hello together, I want to port the Infrared Nec example to CPP. I have a linker problem when I include the xRingbufferReceive function. I have made a small example with the Hello World program. #include <stdio.h> #include "esp_err.h" #include "esp_log.h" #include "esp_system.h" #include "nvs_flash....

Re: EMAC receive not working

Success on LAN8720 as well. Lack of CRS/DV was due to non-populated resister R10 on the eval board which is inline between phy and CRS pin on rmii connector. Once I populated that resister, it all just worked. Rudy, I had already used the mapping of GPIO27 to EMAC_RX_DV in the example but went back...
