Got one of the picqueños (the name is SOOOO epic…).
I’ll try to assemble it soon and give it a try/serve as a betatester.
Here’s some fresh ñ’s for you to copy and paste:
ñññññññññññññññññññññññññÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑ
And also some ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿¿
So you can invent more spanish names.
Take it as a present from Spain.
At least we got it right on the silk screen :)
What are the possible applications for the TCPIP to serial converter ?
It is the web platform with teh SD card on the bottom. It is going to be the simplest tcpip to serial device we can make for simple automation stuff with eg arduino. Hopefully for $25 each.
Indeed, I just saw that it uses the ENC28J60. Is the Arduino library for this chip mature enough already ?
Last time I checked (some time ago) it still missed several features of the WIZ chip.
@Robby: You don’t need the Arduino library for the ENC28J60. This board will handle all of the TCP/IP and then just expose a serial port, which you can connect to your Arduino and use the very well supported Serial library.
@Kenneth: that’s just wicked.
Ok, when I finally manage to get a coupon, I know what the first thing I’ll order is going to be :)
PICqueño sounds great! I will select it from the PCB Drawer! :D
Re: TCPIP to serial converter
I must be missing something. There is a wiki page for it with PCB files and software for download. But no where can I find just a general this is what it is and does. Like an overview or a forum discussion of some type?
Thanks,
Nope, no more than that. These are in development projects, they may never be finished. I havent got to the point of writing any docs on it.
what’s the difference between this CPLD breakout and the others?
It is a different Manufacturer’s chip. So far we only have Xilinx. We have a PCB for Altera and Lattice too now.
“TCPIP to serial converter”:
Normally this is called a TCP/IP-Serial “Device Server”. Similar things with a tad more ‘smarts’ to serve VT100/ANSI serial terminals are called TCP/IP-Serial “Terminal Servers”. Some work at the link-layer as Ethernet-Serial. These devices may have from one to many serial ports. With many ports the term “Console Server” may apply. With +/- serial level shifters the term RS232 and/or RS422/485 will be included. Modern devices like this may include encryption over over the WAN connection (challenge to you DP).
For managing multiple machines (typically Unix/Linux) which are IP networked, instead of using physical terminal servers, these days one usually uses SSH sessions under a window manager such as “screen” [see the screen(1) manpage].
