(JTAG viewer with wigggler)2. Design a PCB (a JTAG viewer with a wigggler)3 Versions4. welding voltage. Check whether the voltage is correct.5. Weld 44b0 + JTAG circuit + JTAG access device of wigggler + peripheral circuit and connect it with the banyant + simulator. The banyant prompts an error, but the 44b0 number can be displayed, which may be 0x0f0f0f only, it means 44b0 is okay.6. solder the crystal + Ram + Rom + peripheral circuit and connect i

supply, or boards are very large, the upper and lower two-layer boards (for example, double-layer boards) must be opened through holes to increase the conduction rate, yes, more stable potential between the Earth and the ground, and some other features (I checked them online), but these passing holes can be non-pattern, because we do not need to weld (7) Manufacturing holesize I don't know if this is a duplicate, but it is useful. The following

Today, Red Hat submitted the final draft of JSR-299To JCP. JSR-299 specification (CDI) (contexts and dependency injection, context and dependency injection), at the same time, the reference implementation of this specification (weld 1.0) ) And TCK (compatibility test suite) have also been completed. To view the javadoc of this specification, click here . This specification defines a series of complementary services to improve applicationsCode. Th

device. At the same time, I/O simulation is also prepared, and the two devices are mounted to four Io devices by jumper. 3. Added 35 keyboard keys for IIC The zlg 7290 does not occupy the CPU. A maximum of 64 keys are supported, and only 35 are used. 4. the LCD interface is modified according to the purchased LCD interface, and can be directly connected using the fpccable. So although there are many changes, they are really transplanted, and the initial debugging is not relevant, just to prepar

appearance and solder joints indicated when the actual part is soldered to the circuit board. Is a pure concept of space, so different components can share the same part encapsulation, the same component can also have different parts encapsulation. Such as resistance, there is a traditional plug-in type, this component is large, the circuit board must be drilled to place the component, after the completion of the drill, insert the component, then over tin furnace or spray Tin (can also be manua

Depressing asp! Depressing PV! The reason is that sometimes the MCU + FPGA/CPLD joint debugging is not enough for me to use epm240t100c5n, instead of drawing a larger resource CPLD, I chose ep2c5t144c8n, which is the most cost-effective FPGA. I drew a board, invested in Shenzhen, waited for the Board and other components, and finally got everything ready one day. I had nothing to worry about, so yesterday I calmed down and shouted a board. It was pretty Haha, but I was scared, i'm afraid I wo

the component's border layout, uniform size, direction neat, stacked. The 1th pin of the component or connector indicates the direction, and the sign of the positive and negative polarity should be clearly marked on the PCB, not allowed to be overwritten; power conversion components (converters, linear transform power supplies and switching power supplies) Linear transform power supply and switching power supply) should have enough heat dissipation space and installation space, the periphery is

start proofing, I also test MPU6050 on the development Board, including to learn what is x, Y, z Three direction of acceleration, and X, Y, z three direction angular velocity, This constitutes a 6-axis stereoscopic model. Also began to learn Kalman filtering and complementary filtering, the use of anonymous four-axis host computer to observe the changes in the data curve before and after the filter, but prepared so much, also learned the use of four yuan to calculate the Euler angle, but the al

resistance is normal, if the resistance is not normal can be used soldering iron resistance ends, such as the resistance for the virtual welding should be able to return to the normal resistance, if the resistance does not return to the regular value, then can be branded See if the resistance is broken, such as fracture, you should trace where the fault. If the resistance is not false welding, and no break, you should trace the incoming have no problem. If the resistance value is normal, the IC

Content Summary The first part: What is a commit hash? Part II: What is merge? Part III: What is rebase? In the first part, we discuss what a commit hash is, and one of the most important features is that commit cannot be modified. The hash value is generated from the information stored in the commit, so if you modify a commit or commit hash, you must create a new commit. We also discussed the hash value of each commit that stored its previous commit. What we're not talking

selection tool to select the two endpoints of the two helix centers, and then press the shortcut key ctrl+j to weld them together, select the Corner radio button if the Connection dialog box appears as shown in Figure 6, and then click OK. This dialog box occurs because two anchor points overlap. 　　 Figure 6 7. Use the direct selection tool to select the outermost two endpoints of the two spirals and then press CTRL+J to

of connected objects. Number? Line Code bodya-> getworld ()-> createjoint ( jointdef) is used to create a joint based on jointdef (joint definition) through a physical world object.In the above example, we only use the distance joint, while many joints are defined in box2d V2. These joints include:? Distance joint. Keep a fixed Distance between two objects. Points on each object are called anchor points. The joint is defined as b2distancejointdef.? Rotate the joint. Allows an object to rotate a

to do with image UV. The solution is to merge (accumulate) The normal of the vertex at the same position. For example, the solution is to use vertex position as the key: struct VertexNormalLess { bool operator()(const Vertex lhs, const Vertex rhs) const { return (lhs.position.x In this way, the normal is superimposed on the vertex with the same position by weight, and even if the vertex at the weld is repeated, their

as copper, if there is a sense of ancient and thick, the grain and essence, in general, can reach the Ming dynasty; if the light and thin decorative flowers, mostly for the Qing Dynasty furnace. You can also focus on rust. You can use the boiling water that is added with alkali to brush the screen, such as fake rust, immediately drop. In addition, the pseudo-rust is not uniform in depth, and cannot be integrated with the device body. It is not smooth in the hands of mo. In addition, the hand st

The combination diagram directly connects components such as diode, voltage-regulated IC 78l05, capacitance 10 UF (SMT) to the D-type 9pin RS-232 connector (PS. this circuit does not

be grounded, the distribution of ground holes should be used to connect to the ground plane. 9. when the welding surface mounting element adopts the wave soldering production process, the axial direction of the resistance and content should be perpendicular to the transmission direction of the wave soldering, and the resistance arrangement and Sop (PIN distance is greater than or equal to 1.27) the components are parallel to the transmission direction in the axial direction. Active components s

Youth is imaginative, and if the imagination be strengthened by discipline this energy of imagination can in great measure be preserved through life. the tragedy of the world is that those who are imaginative have but slight experience, and those who areExperienced have feeble imaginations. fools act on imagina
