Dear Hamster,I am really interested in your work with HDL to interface the "dirt cheap" WiFi module (ESP8266) with the Basys3 Board.I have studied your approach and its very clean and straightforward. I have some questions and I hope you have some free time to answer them.1) regarding file - esp8266_driver.vhdI have understood how to connect to the Wi-Fi network of choice. But you have a command called "AT+CIPSTART="TCP","192.168.1.119",1125". This basically tells the modem to connect to the router on said IP address and start a TCP connection on said port number. I was not able to understand (if the ESP8266 is able to connect to the internet) what IP address it would be sending its data to? Again, basically if "192.168.1.119" is your source IP (data comes from here) then you need to specify where it needs to go right?2) If the ESP8266 module is connected (via FPGA) to a router which has a good internet connection. Can you show me on how to use it to connect to a remote server like dweet or thingspeak so I can upload some data on to that server?This would make this project a real IoT centric platform for connecting sensors to the internet using the low power, parallel computing benefits of the FPGA.Thanking You,Sharat K

can anyone tell me about how to display image from Block ram (gray scales pixels value) via VGA or HDMI?? Is there any working example ???

It is for Spartan 6, but will also work on Kintex.
If you are interested in HDMI, have a look at
https://github.com/hamsternz/FPGA_Mandelbrot/tree/master/src
specifically:

Thanks a lot.....I'm appreciate your help..... But i need very specific.... Block ram to display via HDMI and VGA or RAM to display image
I have stored pixel values in BLOCK RAM by using core generator. I just want to display image from block ram...

I'm execute this example and really thanks..It brings me some confidence

Hi Hamster,
Based on "
"
1. Is it INIT_49 => X"coco", -- for channels 6,7,14,15?
INIT_49 => X"000CC", -- CHSEL2 - enable aux analog channels 6,7,14,15
2. I use Basys3 (xc7a35tcpg236-1) board. Is it compulsory to specify the below?
SIM_DEVICE => "7SERIES", -- Select target device (values)
3. Should I initialize DADDR like this one?
DADDR => "0010110", -- The address for reading AUX channel 6
Thank you,
Shruthi.
