I just started learning ARM embedded system recently, and I have some questions about expansion: I want to expand SDRAM, NOR FLASH, and NAND FLASH. The A1-A (x) address lines of ARM are connected to t...
AT&T recently announced the implementation of the AirGig plan, which aims to use existing power transmission lines to transmit high-speed wireless communication data without the need to build new comm...
Preface: I got the board at 10:30 am on Sunday. I should have come to the forum to tell Sister Soso and express my excitement, but the school's network server is too weak. I have been unable to connec...
Recently, I found in an experiment that when the VSS pin of ad7710 is connected to -5V to collect positive and negative voltages, the reading is very unstable, with a jump of about 5 millivolts. When ...
