刚开始修补RN4020,还没有发现任何显示16位句柄如何分配给128位UUID用于私有特性的东西。我需要这个是因为UART通知只显示远程设备修改了什么句柄,而不是UUID。有?谢谢。 以上来自于百度翻译 以下为原文 Just started tinkering with an RN4020, and have not yet found anything that shows how a 16-bit handle is assigned to a 128-bit UUID for a private characteristic.I need this because the UART notifications only show what handle was modified by a remote device, not the UUID.I'd think/hope there would be an easy way rather than having to parse through the LS output... is there? Thanks.

您好,我使用MPLAB X IDE 3.26和XC16 1.21为PIC24FJ256GA106创建Bootloader和应用程序的组合。我已经将引导加载程序设置为应用程序的“可加载项目”。在应用程序中,我注意到当我调用Bootloader中定义的函数时,链接器给出了一个“未定义的引用”错误。从Bootloader项目中定义的“Y”被正确使用。我是否忽略了一个链接选项来正确地包括“可加载项目”,或者仅仅引用这些函数是不可能的吗?如果它是我忽略的选项,我很好奇为什么在添加一个“可加载项目”时默认不包含这个选项。谢谢。 以上来自于百度翻译 以下为原文 Hello, I am using MPLab X IDE 3.26 and XC16 1.21 to create a combination of Bootloader and Application for a PIC24FJ256GA106.I've set the Bootloader as a "Loadable Project" for the Application. I've noticed in the Application that when I call a function defined in the Bootloader, the linker gives an "undefined reference" error.The #defines from the Bootloader project are used properly. Am I overlooking a linker option to properly include the "Loadable Project", or is it simply impossible to reference those functions?If it is an option I'm overlooking, I'm kind of curious why this isn't included by default when adding a "Loadable Project". Thanks in advance.

假设我的数字芯片 -FPGA输入或其他方面的超调(正负)超过1V。芯片长时间会发生什么?输入端有保护二极管。二极管会放弃吗?利用快速边沿速率,二极管甚至不会抑制过冲。如果芯片完全失效,芯片如何失效?以上来自于谷歌翻译以下为原文Say I have overshoot (both positive and negative)beyond 1V at the input of my digital chip- FPGA or otherwise. What happens to the chip over long time? There are protection diodes at the input. Will the diodes give up?With fast edge rates, the diodes don't even clamp the overshoot. How does the chip fail, if it fails at all?

当使用“和谐V2.04”时,当运行“UnvialSalAdioOx解码器”演示应用程序时,我不能从PIC32蓝牙音频开发板(DMS3200)获得任何耳机音频输出。演示GUI显示音频文件正在播放,但是没有声音。演示,但是很好地播放音频文件正确,如果我使用和谐V1.11音频文件保存在USB闪存存储为wav立体声44.1kHz 32位浮动,我已经尝试了其他WAV采样率也没有运气。该D3332是一个原始的董事会,而不是新版本的红色按钮。任何想法,为什么音频播放是失败的和谐2.04和D3332将不胜感激。谢谢。 以上来自于百度翻译 以下为原文 I cannot get any headphone audio output from the PIC32 Bluetooth Audio Development Board (DM320032) when running the "universal_audio_decoders" demo app when using Harmony v2.04. The demo GUI displays that the audio files are being played, but there is no sound. The demo however works fine playing the audio files correctly if I use Harmony v1.11. The audio files saved on the USB flash are stored as WAV Stereo 44.1kHz 32bit float, I have tried other WAV sample rates also without luck. The DM320032 is an original board, not the new version with the red buttons. Any ideas as to why the audio playback is failing with Harmony 2.04 and DM320032 would be much appreciated. Thanks.

你好,我刚买了ATLYS板(基于Spartan-6)。我已经阅读了参考手册。我也知道如何用VHDL编程,我有ISE 13.1。我想编制一个LED闪光灯,我知道非常简单,但我无法弄清楚如何使用电路板上的LED或按钮...使用MCU更容易...那么,对此有何帮助?-Ali以上来自于谷歌翻译以下为原文Hello, I've just bought ATLYS board (based on Spartan-6). I've read the reference manual.I also know how to program in VHDL, and I have ISE 13.1. I want to program a LED flasher, very simple I know, but I cannot figure out how touse the LEDs on the board or the Buttons...with MCUs things were much easier... So, any help with this? -Ali
