我想知道怎么做，如果我想下载的图像（我已经建立）上的董事会，而不重新编译它。/制作“app”-“平台”下载运行命令是“构建+下载+运行”，对吗？我找不到只下载/Flash的命令（没有构建） 以上来自于百度翻译 以下为原文I am wondering what to do if I want to download the image(I have already built) on the board without recompiling it again../make 'app'-'platform' download run command is 'build + download + run' right?I can't find a command for only download/flash (without build)

你好！我开发了一个基于微芯片DSP库的DSPIC33 FJ128GP802的“信号分析器”，然后在图形模式下在ILI934 1显示中显示一个代码，代码工作得很好，最大FFT大小为1024个点（由于RAM限制）。N和频域同时没有问题，但是由于DSPIC33 EP512GP502的30个额外MIPS（和FLAS/RAM功能），我决定迁移代码没有成功，所有的例程都工作得很好，但是FFT没有。第一个问题是内存映射，编译器没有。允许像“空间（y存储器）”这样的AbbbTues或类似的EP设备投掷一个错误“不能分配…”（我不知道为什么），所以我手动地址：这样做没有地址陷阱中断和代码流没有问题，但不计算FFT使用相同的代码工作。DSPIC33 FJ类似：“SealAlxInDaDA”包含由Time3 ADC采样的数据，在48 kHz触发，屏幕和调试总是显示17000赫兹，并且存储在FFT矢量的结果中的数据从未改变。有人知道为什么在FJ上同样的算法在EP中没有吗？我停止了发展，因为我不知道发生了什么。任何帮助都是非常有希望的。 以上来自于百度翻译 以下为原文 Hello comunity!I developed a "signal analyzer" on a dsPIC33FJ128GP802 based on Microchip dsp libraries for the spectrum, then I write a code for show data in a ILI9341 display in a graphical mode and the code works very well with a maximum FFT size of 1024 points (due to RAM limitation) this code shows time domain and frequency domain without problems at the same time, but due to the 30 extra MIPS (and flash/ram capabilities) of the dsPIC33EP512GP502, I decided to migrate the code without success, all the routines works very well but the FFT not. The first issue was the memory mapping, the compiler does not allow atribbutes like "space(ymemory)" or similar for EP devices throwing an error "could not allocate..." (I dont know why) so I address manually like : fractcomplex vector_complejo[Muestras_FFT] __attribute__((address(0x9000),far,aligned(Muestras_FFT*2*2)));fractcomplex twiddleFactors[Muestras_FFT/2] __attribute__((address(0x1000),near,aligned(Muestras_FFT*2))); Doing this there are not address trap interrupts and the code flows without problems but NOT calculate the FFT using the same code that works on dsPIC33FJ like: p_real = &vector_complejo[0].real ; //Inicializa puntero p_complejo = &vector_complejo[0]; //Inicializa puntero//===================SE MUEVE EL BUFFER DE ENTRADA AL VECTOR COMPLEJO===========for ( i = 0; i < Muestras_FFT; i++ ) { vector_complejo.real = Senal_Entrada ; vector_complejo.imag = 0 ; }//==========================CALCULO DE LA FFT=========== FFTComplexIP (E_Mariposa, &vector_complejo[0], (fractcomplex *)&twiddleFactors[0],COEFFS_IN_DATA); BitReverseComplex (E_Mariposa, &vector_complejo[0]); SquareMagnitudeCplx(Muestras_FFT, &vector_complejo[0], &vector_complejo[0].real);"Senal_Entrada" contains the data sampled by timer3 ADC triggering at 48KHz, the screen and the debug always show 17000 Hz and the data stored in the result of the FFT vector never changes. Anyone have an idea why the same algorithm that works on FJ doesn't in EP? I stopped the develoment because I dont know what is happening. Any help will be very hopefull.

嗨，谢谢你的未来帮助。项目的内容：我必须打开一个门，它有一个带有PIC16LF1459的电柜。我已经开了一扇门，上面有一个PIC16控制的按钮。但是现在我需要使用RID-RC522。我使用了一个库和MCC。当我构建和运行时，我得到了一些关于我的MOSI，MISO，SCK和SDA（CS）WITOUT在RC522上传递的任何信号。似乎有一个通信之间的屏蔽和PIC16PIC从示波器：在下一个引脚：RC522 - PIC16SS（SDA）- \ SSSCK - SCKMOSI - SDIMSO - SDOST--MCLRYYONTY是在ZIP和IM有任何问题。 以上来自于百度翻译 以下为原文 Hi, Thank you for your futur help. Content of the project :I have to unlock a door which has a electric locker with a PIC16LF1459. I already open a door with a button which is control by the PIC16. But now i need to use the RFID-RC522.I use a library and the MCC. When i build and run, i got some signals on my MOSI, MISO, SCK and SDA (CS) whitout pass anything on the RC522. It seems there is a communication between the shield and the PIC16 Pic from an oscilloscope : In the next post PIN : RC522 - PIC16SS (SDA) - \SSSCK - SCKMOSI - SDIMISO - SDORST - \MCLR Everything is on the zip and im available to any questions.

大家好，我的SPI通讯有点问题。当我在示波器上检查我的信号时，我没有CS，但是我可以看到我的数据和时钟。我把我的代码放在下面来理解我的问题。谢谢你，安娜。 以上来自于百度翻译 以下为原文 Hi everyone,I have some trouble with my spi communication.
