keyur's way: LED blinking with Spartan3E

http://keyuracharya.blogspot.com/2013/01/led-blink-vhdl-fpga-papilio-one.html

FPGA basics and tutorial. Avr atmega 8535 projects. January 02, 2013. LED blinking with Spartan3E. I just bought Papilio one. FPGA development board and started to learn Spartan3E. Here is a cool video to start with Xilinx ISE development. The person explained well with another Spartan3E board but most of things remain the same. Here is the counter designed for Papilio One in VHDL. IEEESTD LOGIC 1164.ALL;. IEEESTD LOGIC UNSIGNED.ALL;. IEEESTD LOGIC ARITH.all. Out STD LOGIC;. Out STD LOGIC;. Out STD LOGIC;.

The things what i have made. Newer posts →. May 18, 2012. Just a quick post to show off something I’m working on at the moment. More details to come soon. October 6, 2011. Tired of looking up the commands to compress/uncompress files via the command line in Ubuntu? Don’t know your -zcvf’s from your -zxvf’s? May be just your cup of tea! Is a python script which wraps a bunch of command line compression/decompressions tools together in simple interface with sensible defaults. Want to make a tar.gz? And the...

ともの技術メモ: 12月 2014

http://tomokuns.blogspot.com/2014_12_01_archive.html

電子工作、組込み(Embeded)マイコン、Linux、自宅ＰＣ環境に関する駄文・メモなどなど。人に見せるため・・・というより、自分で見るための日記です。 http:/ tomono.eleho.net の方がメインページ（内容は同じです）になりますので、こちらの更新は遅れがち（というか、思い出したとき）になります。 A/Dコンバータを内蔵していて、Arduinoのシールドが搭載可能。ロジック規模は8000LEのものを搭載しているようなので、NiosIIプロセッサも余裕で入るでしょう。（評価ボードの詳細は ここ. 12539;・・おもわずポチりそうになりましたが、 ALTERAの開発ツールのページ. を見ると、他にもいくつか安価な評価キットがあるようなのでしばらく様子見することにします。（その前に、DE0を使いこなせよ、という話が・・）. それにしても、ある程度の規模までの用途であればFPGA1個に全てが入っていってしまう感じですね。かつての電卓戦争を思い出します。こうして少しずつハードウェアとソフトウェアの境界がなくなっていくのでしょう。 またHack a Dayの記事からです。 しかも&#12289...

http://keyuracharya.blogspot.com/2013_01_01_archive.html

FPGA basics and tutorial. Avr atmega 8535 projects. January 03, 2013. One Second Counter in VHDL for spartan3E. This is the vhdl. Code for LED blinking at 1 sec exactly. I have a Papilio. One which is running at 32MHz. So all I had to do is count 32million (1111010000100100000000000 in binary) clock pulses to get one second. Then I toggled the LED pin. Behavioral of main is. 0) := (others = '0');. 0) = "1111010000100100000000000") then. Led1 = bit1;. Led2 = bit2;. Others = '0') ;. Bit1 = not bit1;. 160;&...

Programming, like chess, women, and music, has the power to make men happy" - Gerald Weinberg. The standard parallel port pulsing setup in Mach3 uses a set kernel speed (25-100kHz) and this is the rate at which it decides to output a step pulse (or not). It is therefore also the maximum pulsing rate. The implementation details are specific to Mach3, but how would you determine an even pulsing pattern? Is a way to achieve this. This could be expressed as:. Var accumulator = 0.5; loop (X times). 1 12345678...
