  1. Use one of the avaliable templates on the sdk to test your hardware design. I recommend to you follow this tutorial to get microblaze running.
  2. Hi guys, Im using microblaze for ethernet purposes: UDP real time communication with my PC ( send audio from 4 microphones directly to PC ~5Mbps). My goal is to have a real-time (or almost) communication with my pc trough UDP ( Pyhton UDP Client in PC ).I already implemented the UDP server in the FPGA using LWIP stack and an I2S Controller for the microphones, but now im stuck at joining both parts of the project: -i receive a sample from the microphones every 25 us , and i prepare an UDP packet of a certain number of samples to send, but calling my function udp_transfer() to transfer the data on microblaze delays more than 25 us, so i lose samples on this loop [ receive (realtime) -> fill UDP packet -> send ] i think i need to implement a buffer ( FIFO or something) to store a certain number of samples so i wont lose samples in the transmision loop. Any ideas of how implementing a FIFO driven by an external vhdl block (my I2S receiver ) but that i easily could access from microblaze ? thanks to everybody and thanks to @PhDev , @zygot , @D@n , @xc6lx45 for replying my last question 😀
  3. Hi guys, im new at this forum, first of all, thanks for the support :) im writing here because i want to send data from an nexys 4 ddr FPGA to my computer. i have tryed with UART, MATLAB FPGA DATA CAPTURE ... but i need a very fast connection that allows big ammounts of data to transfer: i have 4 microphones connected to the fpga, sampling frames of 18 bit at 40kHZ, and i need to record sound and send it to the pc, or directly send it in real time. Hope you guys can help me because im stuck in this proyect and i need to solve this!! 😁
