参数搜索中缺少控制器

嗨，确保点击按钮：[显示所有产品]，不只是：“新的/流行的设备”，并选择“显示所有规格”，有一些时间抱怨参数搜索表中的错误。迈西尔

    Hi,
Make sure to click the button marked: [ Show All Products ] , not just : "New / Popular devices"
and select "Show All specs"
 
There have some times been complaints about mistakes in the parametric search tables.

谢谢，这很管用……不是很清楚。我点击“显示所有8位MCU”，但他们不显示。还必须点击“显示所有规格”…（最好称之为“显示所有设备”…）

    Thanks, that works...
Not very clear though. I click "show all 8 bit mcu's", but they don't show. Still must click "show all specs"...
(better to call it "show all devices"...)

是的，参数搜索（和地图）和Heck一样麻烦，而且已经很多年了。它主要是底层数据库中坏数据的问题——如果你想知道哪些芯片实际上有特定的硬件，唯一可行的选择是在MPASM.Inc文件或XC16/XC32头文件中搜索SFR名称，但这是一个新的低值。Mysil推荐的“8位微控制器产品”（SIC.）HTTPS://www. McCHIP.COM/PARAMCHARTSECHCH/CHART.ASPX选项？分支＝1014只显示182个设备，如果排除AVRs，则下降到118，（可以通过下载电子表格来确认）。早在2016年年中，在Atmel收购之前很久，就有1036个8位闪存设备，所以超过900个设备已经消失了，甚至没有考虑到遗留的EPROM PICS。

    Yes, the parametric search (and MAPS) are as buggy as heck, and have been so for many years. Its mostly a problem with bad data in the underlying database - to the point where if you want to know which chips *actually* have specific hardware, the only realistic option is a text search for SFR names in the MPASM .inc files or XC16/XC32 headers- but this is a new low.  Mysil's recommended options in '8-bit Microcontrollers Products' (sic.) https://www.microchip.com/ParamChartSearch/chart.aspx?branchID=1014 only show 182 devices, dropping to 118 if you exclude AVRs, (which can be confirmed by downloading the spreadsheet).   Back in mid 2016, long before the Atmel acquisition, there were 1036 8 bit FLASH devices, so over 900 devices have gone AWOL, without even considering the legacy EPROM PICs.
