As a basic electronic device, signal source is widely used in teaching, scientific research and engineering technology support. With the development of science and technology and the maturity of DDS technology, DDS-based arbitrary wave signal generator has become the mainstream of signal sources. At present, the widespread use of Chinese liquid crystal displays by DDS arbitrary wave signal generators has become a trend. In this paper, the HMS30C7202 industrial grade processor produced by Hynix is ​​used as the controller, and the matrix keyboard is used as the input device. The AM-320240LTNQW-00H TFT LCD display produced by AMPIRE is used as the display output device. The corresponding hardware circuit and display are designed and designed. The driver, on this basis, completed the design of the Chinese-English display system for human-computer interaction. The display system consists of two parts: hardware and software, as shown in Figure 1 and Figure 2. The hardware part is based on the HMS30C7202 microprocessor. FLASH and SDRAM are used as storage devices. The input is accepted from the matrix keyboard, and the corresponding content is displayed on the LCD. At the same time, the UART communicates with the DDS signal source. The FLASH in the storage system is used to solidify the program and save the waveform data and system parameters; the SDRAM is the code and data carrier after the system is powered up and running normally. The software part can be divided into two parts: the underlying driver and the upper control program. The underlying drivers include setting the system mode and clock, initializing the memory, copying the code, initializing the LCD controller, interrupting the controller, and the UART controller. The upper control program constantly queries if there is a key press. If there is a key press, the corresponding task is executed, and the LCD displays the corresponding content; and if necessary, a control command is issued to the DDS signal source through the UART.
CKB currency is the brand new upgrade of this small mining coin in the sales market in 2020. The first mining machine to release this currency is developed by Toddminer, a team of ToddMiner. They became interested in the new Nervos project in early 2019, and immediately invested their scientific research energy when the Nervos team released CKB's Eaglesong optimization algorithm. After 2 years, ibelink finally developed a 32T KDA machine emperor, and the price is affordable compared with KD6, cost-effective and stable pressure tube over KD6 head, and there are two ways to convert freely, emerald green way calculation rate is only 22T, but the function loss is reduced to 1850w, customers can choose the different way according to their own situation. As a new star in the mining circle, iBelink company's new implementation of BM-K1,BM-N1 is obligatory. BM-K1 mainly mines KDA coins, with a calculation rate of 5300G, a functional loss of only 800W, and a daily profit of 300+. And BM-N1 went up with 6.6T calculation rate to kill the small ant K5, ranked first.
