在文件“dsp.h”中,PI被定义为.#define PI 3.141592653589793 1159973468418516905761718750。为什么这个值用于dsPIC?循环常数为3.141592653589793 23846、26433、83279、50288、yts。

哪个参数可以用作我的屏幕完全重画并显示在屏幕上的标志?我需要做一些功能,在第一次展示时,我会用一些细节,我想使用事件“显示”,但是它们被称为0,5s,我看到了新的屏幕显示。这个等待时间太大了,这个延迟是正常的吗?我知道屏幕不是轻的(双缓冲,JPG作为后台),但是…? 以上来自于百度翻译 以下为原文 Which parameter can be used as as flag that my screen is completly redraw and display on the screen?.I need make some function who init some detail at first show, I think to use event "on show" but they are called about 0,5s betwen i see new screen on display. This latency is too big. Whatever, this latency is normal?. I know that screen is not light (double buffering, jpg as backgroun) but... ?

Dear,all: ST公司用于振动测量加速度传感器?要求如下: 频率响应超过1万范围:0-40克Power:低功耗如果ST公司没有这些传感器,用于水泵,风机和其他工业现场,您能介绍其他公司的传感器吗?以上来自于谷歌翻译以下为原文 Dear,all:ST companies have used for vibration measuring acceleration sensor? Requirements are as follows: Frequency response: more than 1kh Range: 0-40 g Power:Low power consumption Used in water pump, fan and other industrial sitesif ST companies have not these sensor,Can you introduce other company sensor?

嗨,我试图生成直接从Harmony附带的cdc_com_port_single示例派生的USB应用程序的最小可能工作版本。问题是,当设备从USB端口连接或断开时,框架不会产生中断事件。首先,设备必须是PIC32MX270F256D、和谐1_8_1、mplabx 3.35、编译器版本1.42。该设备是只带有USB连接器(和解耦电容器)的裸板。为了尽可能完整,我已经包括了相关图像,比如和谐配置器设置和时钟图。HED),所有的工作正常,返回一个有效句柄,并设置事件处理程序。但是,当设备从USB端口连接/断开时,事件处理程序永远不会被调用。另外,Windows对连接没有反应。在连接/断开USB设备时,不会触发system_inter..c的主ISR例程中的断点。非常感谢您的帮助! 以上来自于百度翻译 以下为原文 Hi,I have tried to generate the smallest possible working version of a USB app derived directly from the cdc_com_port_single sample that comes with Harmony.The problem is that no interrupt events are ever generated by the framework when device is connected/disconnected from a USB port.First the essentials, device is PIC32MX270F256D, harmony 1_8_1, mplabx 3.35, compiler version 1.42.The device is on a bare board with a USB connector (and decoupling capacitors) only.In an attempt to be as complete as possible, I have included what I believe to be the relevant images such as the Harmony configurator settings and clock diagram.When stepping through the INIT state (see app.c attached), everything works correctly, a valid handle is returned, and the event handler is set.However, the event handler is never invoked when the device is connected/disconnected from a USB port.Also, Windows does not react to the connection.While connecting/disconnecting the USB device, a breakpoint in the main ISR routine of system_interrupt.c is never triggered.Any help would be greatly appreciated!

你好,我终于可以把ILI9325驱动程序引入Harmony 2.04了,我想和任何需要它的人分享这个经验。我附上一个PDF,上面有如何与和谐集成的逐步说明,我还上传了ili9325驱动程序模板。把TXT扩展改为PDF.C。感谢您的修改和改进。ILI9325.Zip(10.07 KB)-下载112次
