Examples of our work
|
|
We write DOS/ Windows software using C
|
int chksum( int *a, int n ){ int i,ttl; for(ttl=0,i=0;i<n;i++) ttl+=a[i]; return(ttl);} |
Writing Windows software to exercise a phase-locked loop IC
|
|
We’ve constructed PC based industrial controllers
|
|
Assemble and program a PC based data acquisition system. The PC coordinates the activities of a photocell sensor, A/D and digital I/O board to sort product based on their printed barcodes.
|
|
Circuit design, schematic capture, PCB layout and fabrication, too.
|
|
Circuit design and PCB layout of an ISA based analog multiplexer board
|
|
Mechanical layout and fabrication
|
|
Sheet metal part design and fabrication. We designed the SR2 housing.
|
|
Embedded systems design using microcontrollers and assembly language
|
|
Design and programming of a microcontroller based equipment emulator. We’ve used many microcontrollers, including the x86, 8051, PIC, 6805, and Z80.
|
|
Stepper motor and linear stage controlled by microcontroller and / or PC
|
|
A custom tester capable of precise positioning was designed and built. Stepper motors were connected to linear stages and driven by a stepper motor driver. A standalone control box was designed and built so the tester could be used independently of a PC. For automatic testing and data recording, a separate interface was built so a PC could control the sytem.
