ARM mini computer round up
A selection of computers that are alternates to the Raspberry Pi. These are intestering to look at considering the Raspberry Pi won't be available until september but the Raspberry Pi is now the cult educational computer.

I got a few Raspberry Pi's a few months ago!Chuckt wrote:These are intestering to look at considering the Raspberry Pi won't be available until september
If you don't know what Voltage your country is using, you shouldn't be doing electronics

Re: ARM mini computer round up
Great to see RISC OS is getting some use!
bitfogav - have you done much with your raspberry pi's?

Re: ARM mini computer round up
Well there on the shell collecting dust at the moment I spent hours trying to get the damn thing to work! to begin with I needed the correct SD card, when I got the correct SD Card I spent a few more hours trying to get the thing to run Linux, several keyboards later I eventually got it working and then thats been that apart from that I need to look into Python language to be able to do more with it?.brad wrote: bitfogav - have you done much with your raspberry pi's?
Hopefully theres abit more info and help now that its been out for a few months
heres a good example using the GPIO pins with some Leds:

Re: ARM mini computer round up
You can certainly see the similarities between c, basic and this (which is python right?)
Code: Select all
import time
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
from array import *
a = array('i',[7,11,12,13,15,16,18,22])
for i in range (0,8)
print "setup pin", a[i]
GPIO.setup(a[i],GPIO.OUT)
GPIO.output(a[i],GPIO.HIGH)
count = 0
delay = 0.04
while (count <1):
print "turning on..."
for i in range(0,8):
GPIO.output(a[i],GPIO.LOW)
time.sleep(delay)
for (i>0):
GPIO.output(a[i-1],GPIO.HIGH)
GPIO.output(a[i],GPIO.HIGH)
print(i)
print "done. turning off"
for i in range(0,8)
GPIO.output(a[7-i],GPIO.LOW)
time.sleep(delay)
for (i>0):
GPIO.output(a[7-(i-1)],GPIO.HIGH)
GPIO.output(a[7-i],GPIO.HIGH)
print(i)
print "off"
Re: ARM mini computer round up
yup definitely similar to C and Basic Brad, the hardest part is just trying to get the code to run on the board

Re: ARM mini computer round up
How did you get a few? They sold out quickly and they were limiting them to one per customer.bitfogav wrote:I got a few Raspberry Pi's a few months ago!Chuckt wrote:These are intestering to look at considering the Raspberry Pi won't be available until september
The feedback I got from another board is the Raspberry Pi only has 6 GPIO pins and I'm reading there were quality control issues. It is kind of disheartening. Its not as easy as it appears?
Wondering whether I should wait or pass. I started to really want one and to order one for its availability in September.

Which build did you use? Debian or the newer Raspbian install?bitfogav wrote:Well there on the shell collecting dust at the moment I spent hours trying to get the damn thing to work! to begin with I needed the correct SD card, when I got the correct SD Card I spent a few more hours trying to get the thing to run Linux, several keyboards later I eventually got it working and then thats been that apart from that I need to look into Python language to be able to do more with it?.brad wrote: bitfogav - have you done much with your raspberry pi's?

I would like to teach my son BBC basic on it.
Re: ARM mini computer round up
Im a good customer with RS-Components and Farnell so when it was available to Preorder the Raspberry Pi back in Feb/March 2012 I think? I Preordered one from RS-Components and one from Farnell, both of them got accepted so I received two back in late April, early June?.
My first experience with the Raspberry Pi wasn't a good one but you got to remember I was prob one of the first batches of Raspberry Pi's to be received, and there was little info or help at the time, but ive looked on the website now and there's alot more info for issues if you have any? and its only a small £22 computer? cant really expect it to work like a £800 desktop?
I used the Debian operating system.

Re: ARM mini computer round up
Not bad for the money though is it.
I remember reading electronics magazines back in the 90's and they had these tiny little single board computers but the price tag was in the multiple hundreds of dollars. It's great how these days we can get great hobby gear for such a good price.
