WiFi模块比较：ATSAMW25，ATWILC1000，ATWILC3000，ATWINC1500，ATWINC3400和MRF

我已经与Microchip的支持沟通，我得到了一些反馈。我已经创建了下面的表格，当我得到更多信息时会更新它。

我已经从Microchip获得了一些更新的信息。仍然努力获得更多关于吞吐量测试台的信息…

我用这些芯片已经有一段时间了。这里是RundOnnSAMW25-一个芯片解决方案，内置的CPU为您的应用程序Walc1000——没有板上的TCP iPATWRC3000——没有板上的TCP-IP，在BooTooToWiC1500上——板上的StAtATWCK34上，有BLUTITOTI目前使用的WC1500，它快得多。我们更换了MRF B/G芯片。这可能是你最好的选择。我认为，如果使用Atmel CPU，Stavigc部件只是一个选择。剧院SAMW25将是一个芯片解决方案的好选择。WiCc34是一个选项，如果你需要蓝牙，但是要知道蓝牙堆栈必须在CPU上，而目前只有一个Atmel CPU的库。

    I have been using these chips for a while.  Here is the rundown
 
ATSAMW25 - One chip solution with built in stack an on board CPU for your application
ATWILC1000 - No on-board TCP-IP
ATWILC3000 - No on-board TCP-IP, has bluetooth
ATWINC1500 - On board Stack
ATWINC3400 - On board Stack, has bluetooth
 
 
I currently use the WINC1500, it is much faster than the MRF B/G chip we replaced.  This is probably you best choice.  I think the ATWILC parts are only a choice if you are using an Atmel CPU.  The ATSAMW25 would be a good choice for a one chip solution.  The WINC3400 is an option if you need bluetooth, but be aware that the Bluetooth stack must be on the CPU, and currently there is only a library for Atmel CPUs.
 

我一直在等待Microchip用自己的基准来响应这些模块。同时，我对三个基本模块进行了一个IPEF测试。每个与PIC32 MZ2048 EFH144在大约28英尺LOS到路由器通过WPS2。所有测试都使用O1优化。不幸的是，新的基于ATMEL的模块比MeMF24WN0MA慢。然而，价格的差异有助于我忽略性能下降。类似于Malo的帖子，我注意到StudiWC1500看起来是Microchip的非官方指定的替换为MYFR24W线。我之所以这么说，是因为他们把WiFixEasy-CONFIG演示中的StudiWC1500作为MeTrf24Wn0Ma的其他配置选项，有自己的演示应用程序，但没有WiFiasEasy-CONFIG演示的全面性。StutWC1500和AtWiCL1000之间的价格差异是可以忽略的（F）或大多数应用程序）。此外，AtWiC1500做所有的AtWiCL1000做更多。为了结束它，ATWIc1500可以从AtWiCL1000驱动程序运行，并且具有相同的引脚。这让我认为StudiWLC1000可能会从阵容中消失（只是我自己的观察——没有来自Microchip的词）。



      以下为原文

    I've been waiting for Microchip to respond with their own benchmarks on these modules.  In the meantime, I've performed an iperf test on the three base modules.  Each with the PIC32MZ2048EFH144 at about 28ft LOS to the router over WPS2.  All tests use O1 optimization.
 
Unfortunately, the new Atmel based modules are slower than the MRF24WN0MA.  However, the difference in price helps me overlook the performance drop.
 
Similar to malaugh's post above, I've noticed the ATWINC1500 looks to be Microchip's unofficially designated replacement to the MRF24W line.  I say this because they've included the ATWINC1500 in the wifi_easy_config demo as the other configuration option to the MRF24WN0MA.  
 
The ATWILC1000 has its own demo app but nothing as comprehensive as the wifi_easy_config demo.  
 
The price difference between the ATWINC1500 and the ATWILC1000 is negligible (for most applications).  Additionally, the ATWINC1500 does everything the ATWILC1000 does and more.  To top it off, the ATWINC1500 can be run from ATWILC1000 drivers and has the same pinout.  This makes me think the ATWILC1000 might be dropped from the lineup (just my own observations - no word from Microchip).

随着CPU上的堆栈，性能将取决于CPU硬件和固件。基准使用MZ过程，假设最大频率，只执行IPRF任务。在现实世界的应用中，MRF24WN0MA，其中CPU是多任务堆栈和应用程序代码，并使用较小的CPU，性能将极有可能大幅下降相比，StudiWC1500。



      以下为原文

   


With the stack on the CPU, the performance will depend on the CPU hardware and firmware.  The benchmark uses an MZ process, I am assuming at max frequency and only performing the iPerf task.  In a real world application with a MRF24WN0MA, where the CPU is multi-tasking the stack and the application code, and using a lesser CPU the performance will most likely drop off dramatically compared the ATWINC1500.

真的。然而，我试着测试模块中的差异，而不考虑微。我的应用程序使用PIC32 MZ，需要性能。因此，所有这些IPEF测试都使用堆栈上的微-他们绕过堆栈在StudiWC1500完全。（这就是微晶芯片如何实现基于StudiWC1500的演示）。



      以下为原文

   
 
True.  However, I was trying to test the difference in the modules irrespective of the micro.  My application uses the PIC32MZ and requires performance.  Therefore, all these iperf tests use the stack on the micro - they bypass the stack on the ATWINC1500 altogether.  (This is how Microchip implements the ATWINC1500 based demo anyway).

今天我测试了WC1500的车载堆栈。令我惊讶的是，它表现得最好。我可以得到3.47 MbPS流。



      以下为原文

    Today I tested the WINC1500's on-board stack.  To my surprise it performed the best of all.  I could get about 3.47Mbps streaming.
