Hello,
I have a problem with writing values to the LCD display of the Genesys Virtex5 evalboard which uses a ST7066U lcd driver.
I succeeded to initialize the LCD, but when I want to write a letter into the DDRAM, but when booting the FPGA, the cursor moves for some microseconds one digit to...
Hello,
I'm looking for a Xilinx FPGA evaluationboard with the following features:
- 2 analog-digital-converters
- 1 digital-analog-converter
- microblaze, picoblaze support
Another boundary condition is that it shouldn't cost too much (I'm a student, so I have a finit budget)
There was an...
Hello,
for my receiver I want to use an SA612 as a mixer, but the test of the 1. mixer-part does'nt work, so I decided to test only the local oscillator.
The problem is in the simulation (I was so happy that I found a SA612 spice model) everything works fine, but in reality doesn't oscillate...
i think it should be possible without a kick-off-circuit, i already found one (but with a frequency of 10khz). i think it's a problem with the dimension of parts. anyone an idea?
Hello,
i tried to design a colpitt oscillator (10mhz) in pspice, but there are some "start" problems. i got the data of the crystal oscillator (RLCC-network) of the german wikipedia (Schwingquarz) and the dimension of the parts from this site:
Transistor Crystal Oscillator Circuit ...
