The background is this. The existing circuit uses PAM8403 to drive a 3W 4-ohm speaker. This dual-ended input amplifier chip:A fixed voice chip is added to the original circuit. This chip directly outp...
I plan to use vXWORKS for development: 1. Host machine ----- PC 2. Target machine ----- vxworks 3. Client machine ----- PC 1-2 uses network communication mechanism, 2-3 uses serial port RS422 communic...
I want to use the three-axis acceleration sensor of MSP-EXP430F5529 to detect whether a person has fallen, but I have never used similar functions. I wonder if there is a great god who can give me a p...
1. Introduction to AMR AMR (Audio/MODEM Riser) is an open industrial standard that defines an expansion card that supports both audio and MODEM functions. This design can effectively reduce costs an...
I used KernelIoControl to get the LCD display buffer (16-bit color). Then I wrote the color directly to this buffer, as follows: for(i=0;i
Solved it myself, haha.
Congratulations
Haha, I was worried t...
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
