BASIC firmware for LPC2138

[basicchip]

We have been publishing as a binary the firmware for the ARMweb, this has helped us develop the TCPIP and related code for the ARMs. We are now going to publish the firmware for BASIC on the DINkit USB, which is a generic LPC2138, so this should be usable by hobbyists/educators on nearly any LPC2138 or LPC2148 board. The firmware is still copyrighted, so if you want to use it in a commercial product contact us about a nominal licensing fee ($500).

firmware updated to 7.70 below

[basicchip]

from the Yahoo Forum --

Hello BasicNode,

It is ArmBASIC Kernel 7.57. It is a USB DIN kit.
Also, all the Digital inputs on the flexible IO's seem to be registering and
changing correctly.
The six AD inputs that I am trying to convert to Digital inputs are all
registering (-1).
I noticed I had stopped receiving the forum on Yahoo.

Thanks

Carl

Which version of firmware are you using? Is it USB or Ethernet connected?

Firmware version reported in the Welcome message, which appears when you hit
STOP in BASICtools

PS, I'm going to move this to the Coridium Forum, Yahoo seems to be trying to

I did a quick check on a board here

From the prompt I typed @e002c000

e002c000: 00000F05 15540000 00000000 00000000 00000000 00000004 00000000 00000000

To check to see the AD were indeed setup that way, then tried this program-

#include <LPC21xx.bas>
PINSEL1=0
FIO1DIR=&Hffffffff
for i=1 to 100
FIO1SET=&Hffffffff
wait(100)
FIO1CLR=&Hffffffff
wait(100)
print i
next i

That didn't do what I expected, so I checked the PINSEL register again

@e002c000

still showed

e002c000: 00000F05 15540000 00000000 00000000 00000000 00000004 00000000 00000000

So something is wrong here, so I took a look at the definitions in LPC21xx.bas (didn't see it right away). I was looking to see if there was a difference between the LPC2138 and the LPC2103 there, but no...

OK, so I added this to the BASIC program

PRINT hex(PINSEL0), hex(PINSEL1)

and it printed

0 0

Hmm, not the F05, 1554 I expected

So I looked at the output of the pre-processor (that translates #defines into actual values). That file is in %temp%/Coridium/__user.bpp

And I saw --

print hex(PINSEL0), hex(PINSEL1)

Which should really be

print hex(*&HE002C000), hex(*&HE002C004)

So I took a closer look at LPC21xx.bas, and yes there were definitions for PCB_PINSEL0 and PCB_PINSEL1. Which are consistent with NXPs latest User manual, but earlier ones including our help files used PINSEL0 and PINSEL1. So I added these definitions back into the LPC21xx.bas file. That will get into the next release. In the meantime add these lines to that file

#define PINSEL0 *&HE002C000
#define PINSEL1 *&HE002C004
' LPC2138
#define PINSEL2 *&HE002C014

[basicchip]

PS, the conversion of ADs to IOs has been done for the LPC2103 and LPC175x, we haven't moved that code into the LPC2138, so for now you'll have to do it manually

I just programmed my first DIN Kit with firmware level 7.60.
Flashing a program I have used for firmware 7.57 to check how my inputs were reporting now seems to report different inputs states each time when no inputs have changed. Not sure what is going on.
Also it seems that Comm port 9 is no longer availble but 15 seems to be alive?

For Firmware 7.50, This pin set up worked for inputs and outputs.
#include "LPC21xx.bas"
FIO1DIR OR= 1<<16
FIO1DIR OR= 1<<17
FIO1DIR OR= 1<<18
FIO1DIR OR= 1<<19

Starting with Firmware 7.57, I can’t get the outputs to behave. For the most part they are on except for 2 pins as soon as I load the program.
If it wasn't obvious I am attempting to control the High Current Outputs.

Here I started using the AD inputs as Digital Inputs.This pin set up was working o.k. for Inputs on firmware 7.57 however, when I loaded it into firmware 7.60, inputs states seem to change at random each time I run my input reporting program with no physical or electrical difference in the input.

Not sure if the change in firmware is the issue with my pin set up but I do not know what else it could be presenty. I do not have access to my DIN Kit with firmware 7.50 to test. Not sure if there was published information I missed.

[basicchip]

We found an issue with the port 1 initialization in firmware 7.60 as well as the setup for TIMER

These have been corrected by version 7.70
