Re: Microcontroller implementation with xilinx spartan3 xc3s
Hello libintt,
First of all thank you very much for showing interest.
Well post route simulation sounds a very good idea, but now i am at home so i will test it tomorrow when i go to my lab and will let you know about...
I have designed a VHDL code for fuzzy logic microcontroller. Code is working fine and simulation results are as expected. I am trying to burn the same code on xilinx spartan3 kit that i mentioned. I am using xilinx ise 9.2i for code simulation and testing. And iMPACT to burn the code into xilinx...
I am using cc2500 with atmega32.
I want to use cc2500 in uart mode because i think in spi mode it is too big to handle.
for that purpose i did following things:
1. i reset cc2500 using sres command strobe.(0x30)
2. then i configured the data rate to 9600 by writing appropriate values of DRATE_E...
Re: ft232r problem
one more thing i noticed that out of blue suddenly my ft232 started working but it just transmits over USB and doesnot receive. That is data sent by atmega is received on PC but data sent by PC is not received on atmega.
I tried checking wavwforms at RX pin of ft232 and...
what is boot mode? i dont kno
please kindly explain

thanx folks for ur help
now it is working. the problem was with 1117 regulator. it was not giving out any current. i wonder how did they sold me dead 1117 which gives voltage accurately.
anyways now another problem has crept up. ma pc is not recognizing ft232r. i am using it for serial...
I am using ft 232 with atmega 32 for serial communication over usb.
I have installed drivers properly. hardware is proper too.
Problem is when i connected it initially it worked fine but after 4-5 times of use now it is not working.
As in now my PC is not recognizing ft232. it always says 'usb...
i havent used autoroute facility and have made it by hand. I am using a 16 Mhz crystal. Also, since all the ic's are surface mounted i could not test on the bread board.
The problem is I am getting voltage across the power on led of atmega but still its not glowing
Help
I am designing a development board using ATMEGA 32 and also has other IC's like FT232 and a regulator 1117 (5 volts). Many sensors and LCD are still to be connected.
In the board I am getting all the desired voltage levels at all points but still the circuit is not working. Is there any problem...
BMP to SCH in eagle
I have converted bmp file to eagle sch file but file is not good as in all ICs are not recognized as ICs its just another picture file in eagle window i cant even generate board out of it. is there any way so that i cn gt a proper schematics file which cn b usd to generate...
unsigned char USART_Receive( void )
{
/* Wait for data to be received */
while ( !(UCSRA & (1<<RXC)) )
;
/* Get and return received data from buffer */
return UDR;
}
code is not working....directly copied from datasheet!!!!!...
RXC bit is also not getting set...what could be the...
74138 keypad example
Pat,
Initially I started with crystal oscillator using schmitt trigger and not gate. Though i used crystal of 4MHz i could not get frequency more than 2MHz. My seniors told me that it is impossible to get anything better than that with that osc. So just to make my...
pid pwm ic
There is a good news and a bad news.
Good news is with the new hardware i was able to run motor both in vel as well as in positoin mode, motor ran accurately and precisely as per given values. So my day ended with a successful smile. today morning when i came back and just switched...
pid motor ic
Please dont laugh at me when I say this-
I had given just 7V to motor driver when i swithched it to 12V now its working.
Though its working (ie I am using it in velocity mode and i have fed values posted by you in this forum- Kp = 0x80, accln = 0x08 and velocity = 0x0A4A i have...
