Print a message through EUSART PIC18F45K80

问题 I am trying to send a message to serial to Docklight but I get a null the whole time. I am using a PIC18F45K80 with XC8 MPLAB X. All seems correct in my code but I guess I am wrong. How can I fix it? #include <xc.h> #include "PIC.h" // INITIAL PIN SETUP void PIN_MANAGER_Initialize(void) { /** LATx registers */ LATE = 0x00; LATD = 0x00; LATA = 0x00; LATB = 0x00; LATC = 0x00; /** TRISx registers */ TRISE = 0x07; TRISA = 0x08; TRISB = 0x01; TRISC = 0b00010000; TRISD = 0xEF; PORTC = 0b00010010 ;

update 2 I want to make a program that can play sound (that can say red, green and blue) on my pic 18f4550 there is a speaker connected to the picdem, that part works fine, I wrote the following program with microchip version 6.83 with the C compiler. I need to retrieve the bits value of a .wav file, when I say red (this has a bit pattern). My right question, how can a get the bit value of my .wav file. void main (void) { TRISD = 0x00; // PORTD als uitgang TRISB = 0b00110000; // RB4 en RB5 als ingang TRISA = 0x00; // RA output RCONbits.IPEN = 0; // interrupts INTCONbits.GIE = 1; INTCONbits

9.7. Relocation and Position Independent Code (PIC) In this section we’ll investigate the difference between position independent code (known as “PIC” from here on) and non-position-independent code and how both affect relocation. 在本节中，我们将研究位置无关代码（此处称为“PIC”）与位置无关代码之间的区别以及两者如何影响重定位。 9.7.1. PIC vs. non-PIC Much of the complexity in the ELF standard is due to the need to load shared libraries at different locations in a process’ address space. Objects built to be position-independent are specifically meant to be loaded anywhere in the address space. As discussed earlier, the code in ELF files

Linker file unselected

I am dealing with a problem in my application with the linker file. What's happening is in the explorer tab it seems the linker file it's not "selected" I have to refer that I also have a bootloader. I'm getting an error of "(944) data conflict at address 1FC02FF8h" and I think it's related with that. Can anyone help me on that? Many Thanks. Right click your linker files folder and make sure that the file is not excluded in your current config.

Assembly of PIC

问题 The address of str is stored the stack(can use pop to fetch it, and it's position independent): .text str: .string "test\n" But now the address of str is not in the stack(can't use pop to fetch it, but str(%rip) (RIP relative addressing) is PIC): .text str: .skip 64 This is what I found from my previous question, but I don't understand how assembler decides address of str should be in the stack or not? WHen should I use RIP-relative addressing ,or use pop to make it PIC? UPDATE This is

How to rotate the bits in a word

阅读更多关于 How to rotate the bits in a word

问题 I'm using a dsPIC33F and GCC. I want to rotate the bits in a word once left or right, like this: MSB LSB input: 0101 1101 0101 1101 right: 1010 1110 1010 1110 left : 1011 1010 1011 1010 (In case it's not clear, the LSB moves into the MSB's position for the right rotate and vice versa.) My processor already has a rotate right (rrnc, rrc) and rotate left instruction (rlnc, rlc), so I'm hoping the compiler will optimise this in. If not, I might have to use inline assembly. 回答1: You may write

Python: 截屏

阅读更多关于 Python: 截屏

最近项目中想实现截屏功能，使用的笔记本是高清屏，实际屏幕设置成了150%，所以在截屏的时候遇到个各种问题。最开始使用PIL ImageGrab来截取屏幕，如果本来是100%的设置没有问题，能截取到全屏，但是150%或者其他设置的就会有问题，只能截取到屏幕的左上部分，无法截取到全屏。 from PIL import ImageGrab pic = ImageGrab.grab() # print(pic.size) pic.save(r'C:\Users\test\Desktop\Automation\python\pic.jpg') 但是这个问题很奇怪，也有的机器150%设置，但是执行后没有问题。遇到这个问题后看到网上有个解决方法：在注册表中Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers添加python.exe和pythonw.exe路径信息进去，再次执行程序就能截取到全屏，用python代码添加注册表的话，要重新再次运行程序才能截取到全屏： from PIL import ImageGrab import winreg reg = winreg.ConnectRegistry(None, winreg.HKEY_CURRENT_USER)
