Air724 on MT7688 测速

那套dts有时候不太好用。可以通过reg做如下检查： 1. AGPIO_CFG 1000003C 要想使用sd-d2，必须要确定模组处于单网口模式（20:17位置为1）。ethmode w或 ethmode l GPIO1_MODE 10000060 11:10位置：默认值是00，需要改成01才是GPIO模式。

另外，值得一提的是，由于GC0328是有数字输出使能控制的，所以双目的GC0328做法是DVP直接并联，但SCCB总线的SDA分开就行了，简单粗暴。 OV2640，OV5640由于没有输出使能控制，所以不能这样并联。

大佬快添加啊，已经一个月了，我也想看看完美方案。话说airv2的lcd接口标准的tft显示屏在淘宝其他地方基本找不到，能不能采用中景园的24pin接口标准啊，中景园的tft貌似还挺实惠的，1.3寸的裸屏才8块多。

嗯嗯，已经解决了，谢谢

这是哪个板子？

谢谢，了解了。

optional use case... 4) POE with no screen Maybe you can put pins in the right places to use off-the-shelf POE module. Something similar to this https://item.taobao.com/item.htm?spm=a230r.1.14.64.7cb06c02UjTec6&id=16848013654&ns=1&abbucket=15#detail Another style https://www.aliexpress.com/item/33012224035.html Random 8080 pinouts can be handled by having the FPC on the V831 board support the LCD you are going to sell. Any other pin out will need to make a small PCB with two FPC connectors and remap the cables.

Those two I2S lanes on V833 likely for four mics. TDM I2S mic more expensive than non-TDM ones so with four lanes you can use the cheaper versions. I don't know any other reason for two I2S lanes other than to support 4 mics. Two mics fine on V831 board. Those pins also useful for attaching smart mic chips. https://www.aisonic.com/

I am trying to get this SDK working on a cheap Allwinner SOC. https://github.com/alexa/alexa-smart-screen-sdk That is the SDK to build an Echo Show... https://www.tomsguide.com/us/amazon-echo-show-5,review-6594.html The real Echo Show contains a Mediatek MT8163 and 512MB DRAM. Currently we are targeting H6, 512MB X3 would work too. That SDK depends on having a browser (webkit, chrome, firefox will do) accessible. Current browsers need a GPU so this browser dependency forces a CPU with a GPU.

7629目前联发科还没开放购买, 我估计今年年底时候该方案会成熟起来. 放弃mips, 迎接arm A7

@深圳福锐达科技 默认应该是15-16db , 天线阻抗50欧

ok了，用了官方的ide。我原来以为vscode+插件就是官方IDE。感谢
