Actually, nothing is hidden or implicit at all. :) So, let's fix your
problem for you.

You can set the direction of a pin in any context in PicoLisp. The
code you have in autorun.l must set its direction. Here's how it
works. Think of it as the default state of the pin. Some pins can be
high by default; some can be low. This is MCU specific - This
particular device works this way. The same code on an LM3S8962 Texas
Instruments Cortex clone behaves the other way.

# Will set the dir of PB_29 and turn the blue LED "on"
# automatically.
(pio-pin-setdir *pio-output* 'PB_29)

# Will turn the blue LED "off".
(pio-pin-sethigh 'PB_29)

So, your function should be:

(de high (pin)
   (pio-pin-setlow pin) )

It's regular PicoLisp. No different. Just that it runs on the MCU. :)

Oh! This is quite easy. Can you please use a serial terminal emulator?
I use minicom. It's a nice tool. In case you don't have it, please get
it (or another of your choice) and configure it for 115200 baud, 8N1
and no hardware flow control. So, assuming an Ubuntu GNU/Linux and
minicom:

$ sudo apt-get install minicom
$ minicom -D /dev/ttyACM0

The above should get you the Hempl shell. Invoke PicoLisp directly
from the shell. You can then type away interactively - like you would
with regular PicoLisp. You can also edit PicoLisp files on your SD
card using iv, the vi clone.

Hempl# iv /mmc/autorun.l
Hempl# picolisp /mmc/autorun.l

Please let me know if this helps you. Good luck!

Re: Mizar32 - What order do functions have to appear?

Dear JB, greetings!

Firstly, sorry for the slight delay in my reply.

Please see this [1] link. TeraTerm helps? OR as John suggested,
Termite might work too! Thanks John!

> any special cables for the emulator or is it just the USB power
> cable?

Nothing else at all. Just the USB power cable. :) That cable serves
two purposes - board power and RS-232 emulation over USB (using
Atmel's USB_CDC software stack).

I'm pretty sure Mizar32 can work with Windows - I don't see a reason
why it can't work. The Mizar32 should get recognized as a serial
device. For that, I think you need a few drivers from Atmel. I'm not
very familiar with the Windows side of things.

But for a quick solution, would it be very hard for you to install
GNU/Linux on Windows within a VM? (I know it's an ugly solution). I
can check with the guys at SimpleMachines if they can point us in the
direction of the drivers. I'll post again as soon as I have some news.

> Also, once that's set up how do I invoke Picolisp? Thanks.

Once you have the handshake between the PC and your Mizar32, simply
press "reset" on your board. (SW-2; I guess). In any case, you're
looking for the switch which is away from the voltage regulator IC.
(There are just 2 switches on the board).

Once reset, you should see the Hempl prompt on your serial terminal
emulator. Let me get back to you with more information.

RE: Mizar32 - What order do functions have to appear?

Thanks for the quick reply. I'm not using Linux, my Mizar lives at college 
where I am building my project for college. The college PC's are using Win 7 
and I don't think they have any terminal software installed on them, although 
HyperTerm is installed by default, it's probably blocked as I can't find it. I 
may be able to get hyperterm unblocked or bring in a portable terminal emulator 
on a usb stick, but I'm not sure. Do I need any special cables for the emulator

I got termite but I don't know how to connect it up, don't I need the rs232

Alrighty, well I just bought the rs232 and the i2c display module. Thanks for 
the help :)

Mizar32 - What order do functions have to appear?

[J B]

So I started creating a little program to act as a digital counter with the 
blue led flashing at each change of logic state, it came to my attention very 
quickly that there is some hidden format that the code has to be in and some 
rules that I can’t find written. It seems to me that you can’t set a pin 
direction unless you are going to use it in the immediate program and I 
personally can’t seem to get smaller functions of “sethigh” and “setlow” to 
ever work. Is there like a comprehensive list of the way I need to be writing 
these programs? I experiment a lot and I do not have the vga board so I have no 
console on screen, I’m kinda running blind and need all the heads up I can. 
Thanks.

Perfect way to begin!

Actually, nothing is hidden or implicit at all. :) So, let's fix your
problem for you.

You can set the direction of a pin in any context in PicoLisp. The
code you have in autorun.l must set its direction. Here's how it
works. Think of it as the default state of the pin. Some pins can be
high by default; some can be low. This is MCU specific - This
particular device works this way. The same code on an LM3S8962 Texas
Instruments Cortex clone behaves the other way.

# Will set the dir of PB_29 and turn the blue LED "on"
# automatically.
(pio-pin-setdir *pio-output* 'PB_29)

# Will turn the blue LED "off".
(pio-pin-sethigh 'PB_29)

So, your function should be:

(de high (pin)
   (pio-pin-setlow pin) )

It's regular PicoLisp. No different. Just that it runs on the MCU. :)

Oh! This is quite easy. Can you please use a serial terminal emulator?
I use minicom. It's a nice tool. In case you don't have it, please get
it (or another of your choice) and configure it for 115200 baud, 8N1
and no hardware flow control. So, assuming an Ubuntu GNU/Linux and
minicom:

$ sudo apt-get install minicom
$ minicom -D /dev/ttyACM0

The above should get you the Hempl shell. Invoke PicoLisp directly
from the shell. You can then type away interactively - like you would
with regular PicoLisp. You can also edit PicoLisp files on your SD
card using iv, the vi clone.

Hempl# iv /mmc/autorun.l
Hempl# picolisp /mmc/autorun.l

Please let me know if this helps you. Good luck!
