怎么使用PIC32 SOIC/SSOP的带I/O的音频板

TQFP会更容易，它们都有相当数量的RAM。我从来没有见过不公平的RAM的照片。



      以下为原文

    TQFP would be easier.
 
They all have a fair amount of RAM. I've never seen a PIC with unfair amount of RAM.

好的，让它扩展到包括TQFP，并阐明RAM最好是gt＝128kb。有什么可以推荐的吗？



      以下为原文

    Alright, lets extend it to include TQFP and clarify that RAM is preferably >=128kB. Is there anything you can recommend?
 

嗨，Mikro Elektronika有一个开发板与PIC32 MX460，与音频编解码器VS1053与耳机输出和其他几个外设在船上。HTTPS://Suff.Mikro.COM/SMART-DISPLAs/MikROMIDEA/MIKROMETROMA3/PIC32 MX4板配备引导程序和演示软件的编译器和溴化锂。来自同一公司的白羊座，我也可以与MPLAB X和Microchip编译器一起使用。有6引脚ICSP连接器的脚印在板上拾取3。注意，在这种类型的板上，ICSP连接器上的标记可能是混淆的，丝网上的信号名称是正确的，但是PIN 1标记可能在WR上。再见，问候，Mysil

    Hi,
Mikro Elektronika have a development board with PIC32MX460,
with a audio codec VS1053 with headphone output and several other peripherals on the board.
https://shop.mikroe.com/smart-displays/mikromedia/mikromedia-3/pic32mx4
 
The board comes with a bootloader and demo software for compilers and libraries from the same company,
I may also be used with MPLAB X and Microchip Compiler.
There is footprint for 6 pin ICSP connector to PICkit 3 on the board.
Note, that on this type board, markings on ICSP connector may be confusing,
signal names on silkscreen is correct, but pin 1 marker may be on the wrong end.
 
Regards,
   Mysil

电路板有音频输入吗？



      以下为原文

    Does the board have audio input?

嗨，编解码器有音频输入，但在该板上没有连接。MikROMeRO+板在EdG.HTPSP//Suff.MikROE.COM/SMART-DISPLASS/MIKROMETIAA/MICROMETIA4/PIC32 MX7上有2个音频线输入和2个线输出。编解码器在这里：HTTP://www. vLsi.Fi/En/Studis/VS1。MysIL语言



      以下为原文

    Hi,
The codec have audio inputs, but on that board they have no connection.
 
Mikromedia+ board have 2 audio line inputs and 2 line outputs in connector footprint along the edge.

The Codec is here: http://www.vlsi.fi/en/products/vs1053.html

您好，如果您只是原型，包可能对您不重要。这将是你的决定。我们可以推荐的是PIC32蓝牙音频开发工具包（DV3200 32）。该板具有PIC32 MX470设备与512K闪存和128K SRAM。它是模块化的，使PIM板，使处理器可以改变到其他家庭。我们有几个这样的PIM板可用。在音频编解码器方面，这些也是模块化的。音频有2种可能的I/O路径（虽然所购买的板只有1个）。我们有一个音频编解码器与线输入使用AK464 2（AC320100）。注意，可以同时将2个板放在工具包上。在MPLAB和谐中有应用实例和编解码器的驱动程序。



      以下为原文

    Hello,
 
If you are just prototyping, the package may not be critical to you.  That will be for you to decide.
 
A board we might recommend for this is the PIC32 Bluetooth Audio Development Kit (DV320032).  This board features a PIC32MX470 Device with 512K Flash and 128K SRAM.  It is modular and enables a PIM board so the processor can be changed to other families.  We have several such PIM boards available.
 
In terms of the audio codec, these are also modular.  There are 2 possible I/O paths for audio (although the board as purchased has only 1).  We have an audio codec with a line input using the AK4642 (AC320100).  Note it is possible to put 2 of these boards onto the kit at the same time.
 
There are applications examples and drivers for the codec in MPLAB Harmony.

嘿，我可能已经找到了一个：我正在看使用D3311音频开发板（HTTP://www. MyCHIP.COM/DeavigoToSs/PositDeLiel.ASPX）PICNNO＝D3311）用于PIC32 MX795F512L（http://www. McCyc.com /wwwsFu/En/En545 660）。如果我有PIC32的GPIO引脚，这个DEV板对于我的应用来说是完美的。如果他们没有联系，董事会将不适合我的目的。对于D3311（HTTP://WW1.Microchip .com／下载/ En/DeVicoDC/AbB%20%20PIC32 %20%%Guest.pdf）的用户指南，对于它们是如何连接的不太清楚，我希望通过扩展连接器或类似的东西可以访问它们。是这样吗？买之前一定要知道。



      以下为原文

    Hey I actually might have found one: 
 
I was looking at using the DM320011 audio development board (http://www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=DM320011) for PIC32MX795F512L (http://www.microchip.com/wwwproducts/en/en545660). This dev board is perfect for my application if I have access to the PIC32's GPIO pins. If they are left unconnected the board will not suit my purposes. The user guide for the DM320011 (http://ww1.microchip.com/downloads/en/DeviceDoc/ADB%20for%20PIC32%20User%20Guide.pdf) isn't overly clear about how they are connected, if at all. 
 
My hope is that I can access them via the expansion connectors, or something similar. Is this the case? Need to know for certain before buying.

这个板是否包括对PIC的GPIO引脚的访问？如果我能访问模拟和GPIO输入，那么这正是我所需要的。



      以下为原文

   
Does this board include access to the GPIO pins of the PIC? If I can access the analog and gpio inputs then this is exactly what I need.

事实上，好奇心PICMX470 DEV板（HTTP://www. McCHIP.COM/DeavigoToSs/PositDeLiel.ASPX）？PARDNO＝DM320103）似乎它有我需要的功能，而不让我支付一堆我不喜欢的东西，比如蓝牙和LCD屏幕。它说TAK462（AC320100）是兼容的，而未使用的GPIO引脚可以通过一个头来访问。这里的数据表有点混乱，这是否意味着所有GPIO引脚都将只能访问或仅使用其中之一？



      以下为原文

    Actually the Curiosity PICMX470 Dev Board (http://www.microchip.com/developmenttools/productdetails.aspx?partno=dm320103) seems like it has the functionality I need without making me pay for a bunch that I don't, like bluetooth and an lcd screen. 
 
It says the AK4642 (AC320100) is compatible, and that unused GPIO pins are accessible through a header. The datasheet is kind of muddled here though, does that mean all GPIO pins will accessible or only some of them?
