Re: desktop with a modem and a wireless router

These are just spam-bots that hit the forums once every other day.

They pull something from answers.com and post it in the digital forum.

Re: #2 Hardware Hello World [Post Homework Here]

Doesn't the 3032 have different Vio's for selecting voltages on i/o banks ? Is everything in 1 i/o bank ? I see you can choose 2.5v or 3.3v as output , is that still with 3.3v on all VCC's ? Neat level converter And i'll prob. have to watch out as i dont think my EPM240 is 5v tolerant as the 3032 i...

Re: atmega

Great, i have already bought the complete kit for microcontroller. However i was wondering how does the boot loader get on the chip? Hi Jeremy, The bootloader is put on the chip by a standard AVR programmer, for example an AVR ISP MKII: http://store.atmel.com/PartDetail.aspx?q=p:10500054#tc:descrip...

Re: #2 Hardware Hello World [Post Homework Here]

What do you want posted ? The whole project zipped ? The VHDL file ? Or ? I hope to get my EPM240 in a few days , but have done the homework. On my CPLD PIN_22 is used by the JTAG , so i reassigned to PIN_2 Hi Bingo, This spot is for the homework questions: http://www.pyroelectro.com/edu/fpga/hello...

Hi,

Definitely. As long as an Arduino compatible bootloader is installed, it will work.

What is the fastest CPLD clock that we will be using on the breadboard?

Thanks,

Hi,

Nothing over 1 KHz will be used. The fastest we ever go with the 555 timer is 500 Hz.
