Lpc2000

Hello,

I'm to use the Tinyarm DIP50 that has the lpc2129 and in the user
manual says that it is tolerant to 5V in ports I/O, but in many of the
emails the group I see pullup to 3.3V.  
  
if I want to put an input high I can make a direct pullup to 5V?? 

Regards
       Domingos

Hi All

I would like to make a LAN connection to an LPC2106 design. It seems 
best to use the SPI interface but I don't know much about SPI 
Ethernet controller support.

After checking around I found the Microchip MCP22S80, a 10M device 
with SPI connection. But, apart from a simple overview data sheet no 
more information.

Question: Has anyone a good suggestion for a device (I would really 
like 10/100 if possible but 10M will do for starters). Has any one 
used the MCP22S80 and would they recommend it?

Thanks in advance.

Cheers

Mark Butcher

Mark,

Bit of a tangent, but I got uIP working on the Olimex LPC-E2124 board so
it would be possible to get it working on the 2106 too--it's just bit
bashing.  The E2124 has a 10M CS8900A on it (popular, low-power, easy to
drive).

As for SPI & Ethernet, I don't have any direct experience.

Hi Paul

Problem I have is that the other ports on the LPC2106 are all used 
up... SPI is still free and is probably faster that bit banging.

Cheers

Mark

Mark,
I have not used this chip. I STRONGLY recommend to get the errata sheet and
request the unpublished errata from Microchip for this chip.  I had a very
bad experience with microchip's CAN controller having problems and trying to
get Microchip to admit the problems.

Which microchip can controller ?

Hi Mark,
I do not know of any ethernet controller that supports
SPI interface.
An alternative would be to use the Xport from
lantronix.
It gives you ethernet  connectivity through a serial
port. You can use the maxim MAX3100 or MAX3111 to
interface the SPI to UART.

Viron.

Hello... I visited Microchip's Web Site, and that SPI to Ethernet 
device doesn't have even a datasheet... But seems to be an 
interesting device.
What about using an ISA Card?

Have just had contact with a local distributor who informed me that 
this device (Microchip MCP22S80) is not yet available - it is 
planned for Feb. 2005. It also seems as though it will get (or 
already has) a new name - the ENC28J60.

Still haven't found any alternative which is a shame since it a 
handy way to expand a design without having to add a bus.

Mark,

If you could use a two chip solution, both Phytec and ARM Patch have 
boards that you could use with the LPC2200's and the SMSC Ethernet 
MAC/PHY.  I think the total cost of the solution would be around 
$10.  Check out these links:

Hi,

You can try the Wiznet W3100 device. This device runs a TCP/IP stack
in hardware for up to 4 simultaneous connections. It can be used as an 8 bit
peripheral or through an I2C channel. It can do 10/100.

It isn't SPI but serial TTL signal levels.

It was the MCP2510 and then the MCP2515.  I regret the day we decided to use
this chip.

Speaking of Wi-Fi, an SDIO Wi-Fi card could be a low cost solution
(SDIO is SPI in simple terms). Sandisk and Socket makes such a SDIO
Wi-Fi cards. The major issue here is rather the manufactureres don't
give out the specification of the card.

Hi folks,

My first question is me being a little lazy really! 

Regarding startup code:

I'm writing some code for the LPC2294: does anyone know if it's possible to 
use the startup code such as LPC210X_Startup.s and crt0.s that comes with 
Crossworks with the 2294? 

Regarding modes:

I'm writing some straight forward run-til-complete non operating system code, 
should I just put the processor into supervisor mode and leave it there? If 
not, what is the best mode to put it in? 

Many thanks,

Rob.

Leave it in system mode.  There is no need to switch to supervisor mode.

The startup for these is pretty similar.  You should be able to use 
the same startup for most basic tasks.

It is best to use system mode for these sorts of task. You can then 
use supervisor mode for software interrupts (SWI) if you ever need 
this.

Hi folks,

I'm trying to connect my (very first) LPC2294 target to my board using Cross 
Studio and an Olimex 20 pin parallel port JTAG interface. Crossworks only 
lists Macraigor 14 and 20 pin targets and this gives an error message saying 
it [Crossworks] can't identify the target. Should this driver work with the 
Olimex interface? 

I do have both voltages on the processor and AFAIK I have all the JTAG 
connectors correct. If it's of any relevance at all, I'm running under Linux. 
Also, I have the Olimex interface on the end of a screened parallel lead (how 
short is that ribbon cable? ;-) 

Many thanks,

Rob

Have you successfully connected to another target (e.g. 2106) using the
Olimex JTAG adapter?

Check your JTAG connections against my Wiggler '210x interface:

http://www.geocities.com/leon_heller/lpc2104.html

and make sure that you have the equivalent pins on your target board 
connected appropriately.

You might need to reduce the connection speed for the JTAG interface 
(Wiggler Properties). Also, ensure that you are using the correct 
port on the PC.

Leon

Hi Leon,

>> Check your JTAG connections against my Wiggler '210x interface: <<

Yeah, they look essentially the same (I have RTCLK connected as well). I must 
say, I can't find the DBGSEL pin at all though. There's a mention of it in 
the manual, but it doesn't seem to indicate which pin it is. 

>> You might need to reduce the connection speed for the JTAG interface

Yep, tried that one too. 

I take it that you have used the Olimex interface with the Macgraigor driver 
then?!

Rob

No, I've used my own interface as well as a genuine Macraigor Wiggler.

I couldn't find DBGSEL either, perhaps the '2119 doesn't have one.

I just checked the data sheet, and saw that P1.26 must be low whilst 
RESET is low, to enable debug. Have you done that?

Hi Leon,

Yes, that I had done(it looks like the equivalent to the DBGSEL to me), but it 
did point me in the direction of what *was* wrong! The reset line was 
flapping about, looks like for some reason my reset chip was broken. Seems to 
connect, upload code and step through now. :-) 

All I have to do is find out why it's dissappearing up its own @rse now! ;-) 

Many thanks for your help. 

Rob.

Tsvetan,
Check out the errata sheet for the MCP2515.  The defect that caught our
attension was the one where can not use transmit object 2 or 3 with out
possible loss of data.

It is better to use an LPC2214 or LPC2294 having the external bus but in 
the past I made micro web server using a PIC 18F258 interfaced via i/o 
pins to a CS8900 (that has a parallel interface) and it worked. You have 
to write a function that read/write data to an i/o port emulating a data 
bus. Of course you will not have maximum possible performance but always 
better then using a serial accessible ethernet controller.
