Re: First impressions - Slow, Scary & unfriendly

Unfortunately, the device is marketed "capable little PC", and that to most people, means browsing the interwebs.

Re: First impressions - Slow, Scary & unfriendly

Maybe they are not expecting a CoreI5 experience. Maybe they just expect usable performance which, from what I read in the forum is hard to come by.

Re: VIA's entry into the low cost computer market

You brick the APC if you manage to kill the BIOS. Same is true for the RPi, you brick it if you managed to kill the GPU/SoC. At least for the APC, you can always replaced the BIOS chip as its socketed (it is probably a cheap EEPROM which means its programmable and hacker friendly). On the Pi, good ...

Re: VIA's entry into the low cost computer market

Not sure about that. The RPi SoC cannot automagically read FAT partition on SD cards without running some form of boot loader code which I assume is what the GPU boot ROM is for.

From what I've read, the APC comes with an onboard 2GB storage, enough for a small OS.

Re: VIA's entry into the low cost computer market

How is the APC BIOS different from the RPi GPU Boot ROM? Aren't they basically the same i.e. initialize some basic hardware so the device can boot from an external storage Assuming the BIOS functions in a similar way to a PC BIOS, it just seems an unnecessary (and costly) addition, as indeed is the...

Re: Greenhouse Automation

I have the RFM70. They're good to around 50 ft (maybe more for direct line of sight). I've somehow developed a very crude meshing protocol that lets a node pass message to the nodes around it. It is still very basic and requires an MCU with bigger SRAM (obviously to store routing data). But I got it...

Re: Programming the ARM chip

I'm not suggesting the guy to ditch the RPi. What I'm saying is if he really needs to go to the nitty-gritty of ARM programming (i.e considering a career in embedded electronics, design, etc), then there are more suitable and cheaper alternative to the RPi that are actually created to help anyone st...

Re: Greenhouse Automation

These wireless modules use SPI to communicate with an MCU so it will work with everything that supports SPI. Since I'm using xmega (arduino's bigger brother MCU), it should work perfectly with an arduino (except that most Arduino boards are 5V even though the AVR chip itself supports down to 2.7V). ...

Re: Programming the ARM chip

For a nice way to play with ARM at the bare metal, I suggest the STM32 Discovery boards. They're ARM Cortex-M3 (or M0 or M4) so you're using the Thumb-2 instruction encodings, but you do have control over everything and can boot from flash. It's also easy to disable the USB ST-Link interface and pr...

Re: Possible to attach cheap screen module to Raspberry Pi?

Just some 8 bit micro and a cheap LCD module off ebay. I'm almost done making a crude terminal output for the Pi. It will take the serial output from the UART and format it to fit the 26 chars x 26 lines display. Not very pretty for long boot messages but more than enough to display useful data

<r>I'm serial-enabling this for some cheap terminal-based screen. Granted it won't be able to render fancy/accelerated graphics, it should be more than enough to display some data (readings from temp sensor, ip addresses, kernel debug message, etc).<br/> <br/> <URL url="http://instagr.am/p/KdZvhTxri...

Re: finding a 6'' monochrome LCD for the pi

it shouldn't be hard to interface an LCD to the RPi with a microcontroller in between. You can drive a 20x4 charLCD or a 320x240 TFTLCD with an inexpensive MCU. Just have the RPi talk to the MCU via higher level command (thought the serial port) and let the MCU do the drawing on the screen.
