Hi,
I am new to design circuit.
I am going to design a circuit to measure voltage in milli volt (mV). For this, I decide to use ADC and maybe some amplifiers to amplify my voltage if needed. May I know which relevant ADC I should look for?
Usually, from provided ADC datasheet, what should I...
Hi!
I would like to find a suitable voltage comparator which I can compare milli volts input with very low voltage offset. Any comparator suggest?
Thanks!
Hi!
For the switching characteristic of IC chips, may I know I have to meet the test condition for CL and RL from the datasheets of all 74 series IC chips in order to get the stated propagation delay time? If so, how to connect CL and RL for the chip? in series or parallel connection?
thanks!
Hi!
Below are my C codes using NIOS 2 IDE to send and read data using DE2 board through UART by RS232 port.
Also, I build my own GUI to receive and send data to UART. After I read the data from my GUI and store the data in array prompt [10], I decide to display the array prompt [10] to my GUI...
Hi!
I am now doing a project on delay fault test on 74series chips. The attachment is my quartus II project with design for delay fault test on 7400 (two inputs Nand gates) as example.
Since the chips delays are in nanoseconds, I use pll in quartus to step up the frequency from 50Mhz to 500Mhz...
H!
I do a simple data communication between hyperterminal (from my laptop) and UART (Altera FPGA DE2 board) through serial RS232 port.
May I know what is the settings i need to do with NIOS II IDE software? I have tried several times using Hyperterminal to detect output from DE2 board through...
Hi!
I have create a GUI software which I want to use this GUI software to receive and send data to Cyclone II FPGA DE2 board.
May I know through the Nios II IDE software, how I write the source code to receive and send the data from DE2 board to my own GUI software? Or any libraries about uart...
Hi!
Thanks for reply!
If use UART, I have to use RS232 right? Since my laptop don't have RS232 port, can I use the converter RS232 to USB? If can, will the data transferring speed become very slow?
Hi!
Thanks for reply.
I decide to use 16 pin ZIF socket for my 74 series IC. Thanks for remind.
May I know how you use UART and terminal program to set up? Because I am using Expansion Header from the DE2 board to perform testing logic.
Hi!
I am doing a fyp on fpga based digital ic tester for 74 series TTL IC chips. I am using VHDL code and Altera DE2 board (Cyclone 2) for my project.
May I know how to perform auto detect function on 74 series IC chips? or may i know what is the algorithm for the auto detect function? For...
