Obviously, we need to execute the ARM assembler first, and then the assembler jumps to the C program, but the compiler does not know whether to put the C code snippet or the arm assembler code snippet first, so we need to tell the compiler how to compile and connect. There is an LDS file in which the contents of the file determine the location of each code snippet in the program, and you can see how the file is passed to the compiler in the following makefile file.3. lds file/******************

, and 15 times is output. TC is the number of output records. Each output time, TC is reduced by 1, and the value is 0, one-service mode for stopping DMA and waiting for other DMA requests.

Question: HDU 4003 find Metal Mineral N mining plants are found on Mars. K robots start to mine from s point, and cost between road sections is given to obtain all the mines at the minimum cost. Category: tree-like DP + group backpack Analysis: Conclusion 1: If we start from point I, K robots will return to point I after collecting all the mines with K as the root node, the cost is the sum of the cost of the root node multiplied by K. For each node

The following bare metal program is based on gt2440 and the compiler is a arm-linux-gcc-4.4.3. Program structure: This program only has one SPI. s file. Program process: first, the power-on Reset enters the reset exception. In the reset exception, call the subroutine to close the watchdog, initialize the system clock, initialize the serial port, and finally call SPI to send data, the data sent by SPI is specified in the program. The data sent by this

The first part is to play bare metal in pcduino3. This process allows us to better understand embedded systems and be familiar with the platform we use. First, we will introduce the development environment: Virtual Machine: VMware?

Dalian Network Competition (HDU 4003 find metal mineral) I think this question can be done, but I didn't do it because I didn't see it at the time. Now, if you have time and your status is very good, maybe it can be done, The following code is extracted from the internet. I am not in the status recently, so I am too lazy to think about it. I will put it here for your reference, /* Question: Put K robots into a right tree from the root node, and use t

this method creates a new dark curve, erases the place that is too bright, this step is not very difficult, need patience. 3, with a pen to dig out, parallel gradient pull when you want to follow the structure of the table curve pull. Pull the picture clean, don't let the blue edge appear. 4, Metal ring: Note the width of the ring. Inside a layer, all need to put high light, shadow line to draw out. Each ring is detached to

Create gorgeous metal texture words, the tutorial is not very difficult to make, but need some skills. In particular, the background part of the production, are made with a brush effect. I can't believe it. The text part of the production is relatively simple, basically with the layer style and some auxiliary brush to complete. Final effect 1. Create a file with 800x600 pixels. Draw a vertical line using a pencil tool of size 1 pixels. Use the era

PS production of gold 3D fu character metal texture font Final effect 1. Create a new 800 * 800 pixel file, select the Gradient tool, color settings such as Figure 2, pull out the radial gradient shown in Figure 3 as background 2, first to make the text section. Open the text footage, drag it in, unlock it, move to the right place, then lock the pixel area, and pull the yellow to orange-yellow radial gradient wi

Tutorial to the Friends of the triple introduction of the use of PS made gray metal texture button. Tutorial is not very difficult, suitable for middle and senior PS learners. Let's go down and take a look at the production of the effect chart. Ultimate Effect Chart Let's learn about the process of making the following: 1. Open Photoshop, create a new layer and press shift to draw a circle using the Oval tool. 2, and then double-clic

In fact, the method is relatively simple, and did not make the knife is very fancy, know that metal can do so, if there is time, anyone can create a beautiful guy. Let's look at the final effect: 1. Draw the shape with the pen tool, adjust the handle, make it a little longer than the actual need. 2. Fill: Gradient-star-shaped radiation. Adjust the colors and handles to try simple radial gradients and elliptical g

The text effect of the tutorial is not done with a single layer. The author used 4 of the same text layer, plus a different layer style, and then the fill to 0%, multi-layer overlay get good text effect. Final effect 1, new document 550x330 pixel, background black, input evil word, color does not matter, font Swis721 Blk BT, size 172 points, italic. 2, will fill zero, and then copy 4 layer, renamed as follows. 3, select Evil1 layer, add stroke layer style.

Photoshop to create a rusted metal mesh of text effects tutorials, I hope you like! Final Effect preview: Final effect 1, first we need to define a point style. Creates a new 100x100 pixel file with a resolution of 300 pixels per inch. Background padding is black. With the ellipse selection tool, set to a fixed size, height and width of 24 pixels. Click anywhere on the canvas and click in the selection box to drag and place the upper-left corner of t

Make the final effect diagram of the hollow word on the corrosion metal block 1. Create a new file, image size is 600x400 pixel, color mode select RGB mode, resolution set to 300, select white background.2. First new layer 1, named ' Cuboid ' and fill this layer white, execute menu-filter-render -3d transform, select the Cube tool on the left in the 3D transform Settings panel, pull a three-dimensional square in the middle of the canvas area, and t
