Recently on the Raspberry Pi 2 toss video, used to do FPV, but found that the 2.4G control will seriously interfere with 2.4G WIFI, in the open control when my desktop + external USB card is frequently dropped. Consider a bit, although the 5.8G frequency band is lower than the 2.4G penetration, but at this stage 5.8G is cleaner, and 5.8G and 2.4G do not have a frequency-doubling relationship, it is not easy

Q: How to use the wireless card, let the Raspberry Pi get rid of network cable bondage?A: First of

system on the USB hard drive, but SDcard still has to be able to open the machine. When using an external hard drive, if the hard drive is not external, I am afraid that Raspberry Pi can not be used for so much electricity, it is possible to switch to a USB hub with an external source. The Raspberry Pi is a boon for

keep your eyes wide open for chip models. Because this series of chips have different versions, and the pl-2303h, Pl-2303hx (Rev A) and pl-2303x chips, the latest version of the driver is not supported WIN8.The Win7 and Win8, which automatically installs the drive function, automatically download and install the latest version of the driver after checking the device, so that the brush board with the above

: ili9325_gpio_driver_rpi.diff You can also download it from my resources: Http://download.csdn.net/detail/canyue102/6735059 This patch is based on the 3.6 kernel. different versions of the kernel may be different. Just change it. First, put the diff file under the kernel root directory, and the terminal enters the directory: patch -p1 Then the source code of the TFT kernel is added to the kernel. make menuconfigYou can see the ILI9325 option under device
