spliced together. When using memory, you need to be aware of whether the interface timing meets the requirements. (for example, in the design of 2D/GPU, I use the memory compier to generate various SRAM as required)ConnectionThe connection includes the chip's signal connection, the power cord and the clock line.? In deep submicron designs, wires cannot be simply viewed as ideal connections, and metal wires have capacitive, resistive, and inductive ef

Touch screen Driver Control Based on C8051F020 [Date: 2008-10-29] Source: foreign electronic components by Zhu PINWEI, Han xiaoxin [Font:Large Medium Small] 　 1 IntroductionCurrently, touch screens and LCD screens have become common input and output devices for embedded computer systems. Touch Screens include resistors, capacitors, surface acoustic waves, infrared scans, and vector pressure sensing touch screens. The most commonly used touch screens are four-or five-wire

case, interrupttype is set to sysintr_touch_changed. The remaining actions are basically the same as the above process. 5 Windows CE touch screen CalibrationThe resistive touch screen must be calibrated. The application requires reference values to convert the received touch screen coordinate data into screen coordinates required by the high-rise software. Ideally, the calibration program runs once during the initial power-on test of the product, and
