Hi there. I've been programming using a parallel byteBlaster-type lead, attatched to an old 486, via a network connection to my laptop. This is because my laptop is devoid of parallel or serial ports (oh, the foresight). I hear I can't use USB to Parallel adaptors (arse!) and I can't imagine me finding a pcmcia parallel adaptor (though I could make one..?) and looking on alteras site reveals they want about �150/$300usd for their USB baster. Nads to that - Anyone know of anywhere selling a usb programmer for sensible (hobbyist) amounts? Or a way out of my situation? Thanks. -Alan / randomdude
USB JTAG programmers?

HI Alan, A freind of mine is working on a design to make a USB programmer for Altera and Xilinx. I think he has the HW working well but working on the SW side (that is the trickey one), but I will ask him if he is interested in sharing his ideas here with others.

There is a PCMCIA to Parallel-Port adapter available: QUATECH SPP-100, Single parallel port PCMCIA card for about 160,00 Euro, it worked well on several PC�s... And for just configuring - have a look at the FTDI chips and bit-bang app-notes: http://www.ftdichip.com with best regards, Peter Seng ############################# SENG digitale Systeme GmbH Im Bruckwasen 35 D 73037 Goeppingen Germany tel +49 7161 75245 fax +49 7161 72965 eMail p.seng@seng.de net http://www.seng.de ############################# "Alan Randomdude" <randomdude@gmail.com> schrieb im Newsbeitrag news:d2b05bc6.0412261533.58ba2077@posting.google.com...> Hi there. > > I've been programming using a parallel byteBlaster-type lead, > attatched to an old 486, via a network connection to my laptop.

The AT91SAM7S64 is nice for the job. * USB Client * ARM7 running at 48 MHz (will not handle 70'C at this temp though) * Built in Flash and SRAM * High speed synch interface for JTAG Master This should be MUCH MUCH fatser than bitbanging. There is of course the small matter of programming... The AT91SAM7A3 is even better, but availability of production part is later. Couped with a dataflash on the SPI bus you coul dbuild a device which looks like a USB Mass Storage Device so you could easily download the bitstream, and at powerup the ARM would configure the FPGA(s) Too lazy to do it myself, but I am sure it would be sellable.

A new rev comes this month, which will add some nice functionality I cannot really talk about just yet. Order 5 samples free of charege directly from Atmel or disti. There are many companies working with the part at the moment. -- Best Regards, Ulf Samuelsson ulf@a-t-m-e-l.com This is a personal view which may or may not be share by my Employer Atmel Nordic AB

From your application that generates a bitstream, you define the location of the saved file to be on the flash disk. Lose one step in the development process = faster turnaround time. The FTDI solution is faster and easier to implement, but this is much nicer... I think that the configuration of the FPGA will be much faster as well.>-- Best Regards, Ulf Samuelsson ulf@a-t-m-e-l.com This is a personal view which may or may not be share by my Employer Atmel Nordic AB
