[问答] 谁能给我推荐一个中档的DSP板来玩吗?
110 DSP PIC

大家好,我已经是一个微€€芯片PIC用户2年了。主要使用16F和18F系列。我真的很高兴他们,但我也想进入世界的信号处理。不打算做一些幻想。只是想玩DAC,产生一些声音,等等。PIC16F系列通常都带有双线包,您可以直接插入您的面包板。然而,据我所知,我不能以类似的方式使用dsPIC,因为它们的振荡速度对于电路板来说太高了。我不是那么熟练。因此,我正在寻找一个数字信号处理器开发板。我对编程图片非常熟悉,所以PIC开发板会很好。不过,我也听说德州仪器公司也有一些很棒的dsp芯片。谁能给我推荐一个中档的DSP板来玩吗?谢谢您。

    Hello people,

I have been a microchip PIC user for about 2 years now. Mainly, I use 16F and 18F series. I am really happy with them, yet I would also like to step into the world of signal processing. Not planning on doing something fancy though. Just want to play with DACs, generate some sounds, etc.

PIC16F series usually come in dual-in-line packages, which you can just plug into your breadboard. However, as far as I know, I can't use dsPICs in a similar manner because their oscillation speed is too high for breadboards.

However, I can't build a dev-board by myself. I am not that skilLED.

Hence, I am looking for a digital signal processor development board. I am very familiar with programming PICs, so a PIC dev board would be good. However I also heard that Texas Instruments have some great dsp chips too.

Can anyone recommend me a mid-range DSP board that I can play with?

Thank you.

虽然在黑板上使用DIP dsPIC是可能的(时钟信号不必超过8MHZ——速度可能更慢),但是使用启动器工具包就不那么痛苦了。一些可能性来自Micro.:*Explorer-16(具有多种CPU选项)*DM330018(“dsPIC33EV 5V CAN-LIN STARTER KIT”)-oExplorer-16板有时在e***上提供(稍加使用),价格合理:)其他启动器套件/开发板可用。为什么不四处搜索一下呢?是的,德克萨斯仪器和模拟设备也有DSP。关于工具和C成本,它们是“来自另一个世界”。首先,DSPIC非常好。

    Though it is possible to use a DIP dsPIC on a breadboard (the clock signal need not exceed 8 MHZ - slower speeds are possible), using a starter kit is less painful.
Some possibilities from Microchip:
* Explorer-16 (with quite a variety of CPU options)
* DM330018 ("dsPIC33EV 5V CAN-LIN STARTER KIT") - one of the rare(r) 5V dsPICs
 
The Explorer-16 board is sometimes offered - slightly used - on e*** for reasonable prices :)
 
Other starter kits/dev. boards are available. Why not search a bit around ?
 
And yes - Texas Instruments and Analog Devices have DSPs as well. Regarding tool and µC cost, they are 'from another world'. To start with, dsPIC is quite nice.

@TheHowitzer,我想说开始使用PIC33最简单的方法就是得到一个28PIN SDIP版本并将其插入到黑板中。将3V3和OV加入到标签中。一个10UF到VCAP。向MCLR增加10K上拉电阻。准备好摇滚乐。将6针头安装在面包板的空白区域中。链接到MCLR,3V3.0V,PGC,PGD。F**K-MPLABX OFF。获取MPLAB892的副本。插入一个皮卡3。设备将被认可。世界你的牡蛎…不再80秒8位。你好90年代16位T Yorky

    @TheHowitzer,
I would say that the simplest way to get started with PIC33 is to get a 28 PIN SDIP version and plug it into a breadboard. Add 3v3 and ov to the pins labelled. A 10uF to the Vcap. Add a 10k pull up resistor to MCLR. And its ready to rock'n'roll. Fit a 6 pin header in a blank area of the bread board. Link to the MCLR,3v3,0v,PGC,PGD. F**k MPLabX off. Get a copy of MPLab8.92. Plug in a PICkit3. And the device will be recognised. The worlds your oyster...no more 80s 8bit. Hello 90s 16bit.

我是面包板的忠实粉丝。我用dsPIC直接插入面包板很长时间,没有问题,还有外接振荡器。我也经常使用插座,类似于下面所示的插座(如果图片显示正确)。它简化了插入,但基本上一切都在电路板上。我使用了数百个不同的照片,来自不同的家庭有这样的插座,他们都工作得很好。

I am a big fan of breadboards.
 
I used dsPIC inserted directly into breadboard for a long time without problems, with external oscillator too.
 
I also often use sockets, similar to one shown below (if the picture comes out right). It simplifies insertion, but essentially everything is on breadboard. I used hundreds of different PICs from different families with such sockets, and they all worked fine.

大家好,谢谢大家的评论。我会重新考虑在工作板上工作。Hello Yorky。谢谢你的评论。除了一部分,我什么都懂。为什么我们要把MPLABX关起来?我觉得它是一个很好的编程环境。但是编程不是我的主要职业,所以也许我错了。我想知道你为什么这么想。为什么我要获得MPLAB892.我还认真搜索了一个双列直插式包配置的DSIC33,但我失败了。当我在A***res和E***上输入dsPIC33时,页面上都充满了垃圾。但是,我可以很容易地找到dsPIC30系列的双联机软件包。我做错了什么吗?我可以用DSPIC30系列吗?或者我在哪里可以找到一个DSPIC33用于面包板呢?谢谢你的建议。实际上我到处找过,想找一个好的开发板。我看过Microstick II,它还附带了一些高性能芯片。然而,这让我很紧张,因为我知道开发板也可以有学习曲线,考虑到它已经安装了USB端口,这会使一些引脚进入占用状态。你能否以通常使用PIC的方式使用Microstick?

    Hello people.
Thank you all for your comments. I will reconsider working on a breadboard.
 
 



Hello Yorky.
Thank you for your comment. I understand everything except one part. Why do we "f**k mplabx off" ?
I find it as a good programming environment. But programming is not my main profession, so maybe I am mistaken. I would like to know why do you think so. Why should I get MPLab8.92.
 
Also I have seriously searched for a dsPIC33 in a dual-in-line package configuration but I failed. The page is filled with rubbish when I type dsPIC33, both on A*****res and E***.
 
However, I can easily find dual-in-line packages for dsPIC30 series.
Am I doing something wrong?  Is it okay if I go with dsPIC30 series? Or where can I find a dsPIC33 for breadboard?
 
 

 
Hello du00000001,
Thank you for your advice. I have actually searched around, trying to find a good development board.
I have seen Microstick II, which also comes with some high-performance chips. Yet this makes me nervous because I know that development boards can have learning curves as well, considering it already has USB port attached, which will get some pins to an occupied state.
Can you use Microstick in a way that you normally use a PIC?

你好,TheHowitzer,到现在为止我还没有用过MICROSTICK,但我想USB是电源/调试端口。因此,有效地没有引脚丢失。EV-CAN-LIN板就是这样。BTW:Excel -16板是用于具有较高引脚数的部件。有相当多的所谓的“PIM”模块适合于探索者16。还有-IIRC-还有一个无人机PIM的选项,您可以将您选择的派生工具焊接到其中。如果您想找到PDIPdsPIC,请访问http://www..hip.com/ParamChartSearch/Chart.aspx?BrcCHID=8194,向右滚动,在“包”列中输入“PDIP”。包类型PDIP和SPIP应用。具有(S)PDIP包选项的dsPIC在后缀的最后位置具有数字1或2,指示引脚计数为14或18resp。20或28。这将有助于如果你想去一个面包板的设计。

    Hello TheHowitzer,
 
I haven't used a Microstick until now, but I guess the USB is power supply/debug port.. Thus effectively no pins 'lost'.
The EV CAN-LIN board is that way.
BTW: the Explorer-16 board is for parts with higher pin counts. There is quite a selection of so-called "PIM" modules fitting the Explorer-16. And - IIRC - there is also an option for unpopulated PIMs where you can solder the derivative of your choice onto.
 
If you want to find PDIP dsPICs, go to
http://www.microchip.com/ParamChartSearch/Chart.aspx?branchID=8194, scroll to the right and enter 'PDIP' in 
the 'Packages' column. Package types PDIP and SPDIP apply.
dsPICs with (S)PDIP  package options have the digits 1 or 2 in the last position of the suffix - indicating pin counts of 14 or 18 resp. 20 or 28. This should help if you want to go with a breadboard 'design'.

HeloDuo090001,我重视开发板上提供的信息。我可能会跟一个探险家-16的董事会,考虑到它也将帮助我在未来的情况下,我觉得有必要升级系统。至于DIP DSPICS。在列表中,我可以找到一个具有双列直插式配置的模型。问题是,我找不到任何销售这些芯片的地方。不在我的祖国,不在E****************ss,也不在Al********************ss。但是,当我在这些网站中键入dsPIC30时,我可以很容易地找到许多型号。如果你能帮我做这个,我会非常感激。直接从Microchip购买是一种选择吗?

Hello du00000001,
 
I value the information you provide on development boards. I may go with a Explorer-16 board, considering it will also help me in the future incase I ever feel the need for an upgraded system.
 
And as for the DIP dsPICs.. In the list, I can find the model that do have dual-in-line configuration.
The problem is, I can't find any place selling those chips. Not in my home country, not in E**y, not in Al******ss.
 
However, when I type dsPIC30 to any of these websites, I can easily find many models.
 
I would be really grateful if you could help me with this one.
And also.. Is buying directly from Microchip an option?

不要买这些。它们过时了。你可以从微芯片上买到DSPIC33:HTTP://www. MicroChIPDouth.Time/MyYON可以在28引脚DIP封装中使用。看看那些以“02”结尾的部分,这些将有28个别针。然后选择DIP包——“-I/P”或“-I/SP”附加到零件号上。

Don't buy these. They're obsolete. You can buy dsPIC33 from Microchip:
 
http://www.microchipdirect.com/
 
Many of them are available in 28-pin DIP packages. Look at ones with part number ending with "02" - these will have 28 pins. Then select the DIP package - "-I/P" or "-I/SP" appended to the part number.

不知道你的位置,但你应该可以直接从微芯片购买。如果你有点幸运(意思是你的衍生品在样品程序中),你甚至可以免费获得样品:。

“榴弹炮”,F**MPLABX OFF。获取一个MPLAB892的副本,“作为初学者MPLAB892更为合作。当你怀疑自己在做什么时,确保测试的某些方面是很好的……只要把MPLab的所有调试工具放在一边,简单地从“配置”菜单中选择PIC设备。MPLab现在对你的设备感兴趣,只需选择“程序员”菜单中的3。MPLab现在想与一个你的设备连接到它的皮卡3通信。只要看看输出窗口,出现一个拾取3标签,如果你插入一个拾取3,它立即显示其状态。它将更新它为您的设备,如果需要的话。如果你拔掉插头,就会被告知是拔掉插头的。如果你把PICkit 3插到黑板头上,它会立即通知你设备代码以及它是否正确。如果代码是00000,这通常是一个布线错误。在错误时,MPLabX只是看起来说“找不到设备”,然后气喘吁吁地摺起胳膊!尝试一个PIC33 FJ128GP802。只要使用内部FRC。当你得到更多的知识,你会发现如何旋转这个7.3 MHz到79~80MHz。T Yorky(注:一旦你的面包板工作了。并且你已经测试了几个LED,你可以移动到MPLABX,知道你有一个工作原型。

    @TheHowitzer,
"F**k MPLabX off. Get a copy of MPLab8.92."
As a beginner MPLab8.92 is a lot more co-operative. When you have doubts about what you are doing it is good to have assurance about certain aspects of your testing...
Just putting all the debug facilities of MPLab to one side, Simply select your PIC device off the 'Configure' menu. MPLab is now 'interested' in your device.
Simply select PICkit 3 off the 'Programmer' menu. MPLab now wants to communicate with a PICkit 3 which has your device connected to it. Just look at the output window, a PICkit 3 tab appears and if you plug in a PICkit 3, it immediately shows its status. It will update it for your device if needed. If you unplug, you are informed it is unplugged.
If you plug the PICkit 3 into your breadboard header it will immediately inform you of the device code and if it is correct. If the code is 00000 this is normally a wiring error.
On errors, MPLabX just appears to say 'can't find device' and folds its arms in a huff!
Try a PIC33FJ128GP802. Just use the internal FRC. When you get more knowledgeable you'll find how to spin this 7.3 Mhz up to 79~80MHz.
T Yorky
(Note. Once you have your bread board working. And you have tested a few LEDs, you can move to MPLabX with the knowledge that you have a working prototype.)
