I found the solution. My initial value assigntment method was for simulation, not for implementation. In order to implement initial values, attribute method should be used.
Working code :
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL...
Hi,
Look up tables consume too much logic source if table is large. I want to store some data on block ram. Data is loaded as initial values to bram. Ram write is disabled, so it will be like a ROM operation.
When i try to read RAM, it always reads zero, is there something wrong with initial...
Thanks,
I know the definition of Iol & Ioh. What i dont understand is "what is the max current for a pin". They dont specify the max current at the datasheet, i wonder if i can drive a 5mA led direcly.
Do i have the option to chose 4ma driver or 16mA driver for a pin?
I am confused about the maximum pin currents (IoH & IoL) of Xilinx xc3s1500.
Below, there is the datasheet, at page 62 & 63 these current values are specified. There are current values from 2mA to 24mA for LV type input-outputs, which values i can use...
previously done final year projects using motor
Which type of motor are you planning to use, brushless dc or brush dc ? For brushless dc motor control there are plenty of application notes on Microchip's website.
