Welcome to our site! EDAboard.com is an international Electronics Discussion Forum focused on EDA software, circuits, schematics, books, theory, papers, asic, pld, 8051, DSP, Network, RF, Analog Design, PCB, Service Manuals... and a whole lot more!

Google for "angle estimation", "gyro drift correction", "direction cosine matrix" and "kalman filter" - you cannot cancel drift with gyro itself. You need an accelerometer (and maybe magnetometer, which depends on application) as reference for gyro drift cancelling.
Re: Noice Cancellor Mode in ATmega32
In noise cancelling mode, CPU is in sleep state for A/D conversion time - no HF noise generated. Interrupt wakes CPU from sleep state just after A/D conversion is finished. Variable "adc_data" is global and is probably declared elsewhere.
Hi,
what frequency you are running your PIC? From datasheet minimum pulse width for EN is 230ns or 450ns and data setup 80ns or 195 ns, so your EN = 1; asm("nop"); EN = 0; is not enough!
Minimum E cycle frequency is 1ms, so __delay_ms(1) between commands is enough. I also recommend place one NOP...
Hi,
assuming "3 pin dc servo motor" means classic RC servo, your control signal must be:
- period 20ms
- positive pulse 1us to 2us
- 1.5 us = neutral (center)
- 1us maximum anti clockvise
- 2us maximum clockwise
This signal can be generated by PWM (Timer) block or by software.
If it is not RC...
Hi,
at first refer to maual of your ESC, because all of today's ESC have inbuilt check for control pulse width and correct position of throttle stick on RC transmitter after power up. If ESC is not satisfied with input signal characteristic, then it makes beep..beep and maybe many other nice...
In OrCAD and other similar systems, power and ground layers are treated as planes. Thery are displayed inverted for drawing speedup, so pads in those layers are holes in copper plane. If you need only one ground and one power, use power and ground plane. If you need multiple power lines (3.3V...
cm2040 lcd
Commads dedicated for writing into CGRAM is completely missed in your LCD.C and LCD.H. Have you read any datasheet of character LCD? Try one from attachment.
On page 12 you can see complete commands for LCD control. Because character LCD drivers are compatible for long time, these...
alphanumeric lcd rountines
If it is character LCD with "standard" controller (probably yes), you have first eight chars (code 0..7) of character generator located in CGRAM. You can define bit pattern i 5x7 pixels for each char in CGRAM a load it to LCD just after initialization. I used it many...
convert schematic to fpga
I'm not using it, because i write code directly without schematic, but in OrCAD Capture you can create project for CPLD / FPGA design. Toolbar for Compile / Synthesis / P&R and simulation appears next to standard toolbars. Then you can draw schematics with sybols...
Re: graphical interface
FPGA is probably best way. You can generate arbitrary video signal and make some hardware acceration for graphics.
Here is link to VGA controller, character generator and bouncing ball implemented in XILINX FPGA:
**broken link removed**
and here Pong game example...
orcad symbol xilinx
You are right - my misunderstanding. I use @ltera's FPGA and in QII is possible to export .PIN file, than can be used for some automation of creation Capture symbol, but i don't know Xilinx. So, yes, it is tedious...
xilinx fpga orcad symbol
- Layout Plus 10.5.0, but maybe in sooner versions too.
- From Layout's shell select Tool/Library Manager - Library Manager runs.
- In Library Manager's menu select library and then click Create new footprint button. Dialog appears. In lower section of dialog called...
vhdl to schematic
It depends on CAD sofware. OrCAD, PADS a others may have VHDL generators. Instead you may use Qu@rtus or ISE schematic editor and redraw your design entirely. Presonally, I do'nt use schematic entry - direct writing VHDL code is better. Regards Pavel.
