I’ve got a MCF5282 that I’m trying to use PDD4 as a GPIO on.In my setup code, I’ve got: MCF5282_GPIO_DDRDD = 0x10;/* cs on dd4. */
I\'ve been hacking away on an ARM based device (Freescale i.MX27 ADS) with a built-in screen for the past few days. The device is running a modified, minimal GNU/Linux system, with no window managemen
DNS is not working on my embedded device, I can do ping to 74.125.77.147, but ping to google 开发者_运维问答\'s ip address 209.85.231.104 works but ping google.com is not working.
i am开发者_运维问答 working on embedded devices where it is common that you handle some hw interrupt events with c code (like catching a pressed button, or let some LED´s blink), i was wondering if a
I\'m trying to measure ambient brightness values with a CdS light-dependent resistor (R2 in the below diagram.) R1 is a known value, and the resistance of R2 has an inverse log relationship with the c
I want to design a device that supports both cellular connectivity ((ie. HSDPA/HSUPA) for high-speed downloads/uploads and telephony) and heavy multimedia applications (like playing streaming video in
I need to manage a memory heap, with the constraint that this memory should only be written to, never read, i.e. the malloc implementation should keep the bookkeeping information separately from the h
So I\'m starting to get a feel for what sets functional programming apart from imperative programming. So like any good convert I\'m looking at things with the Haskell hammer and trying to imagine how
I require the SPI header file so I may write a SPI master and slave for two PIC24FJ64GA002. I had one but I accidentally deleted it. Please may some one send me a link to download the header. As soon
Very often malloc() is absolutel开发者_JS百科y not allowed when programming for embedded systems. Most of the time I\'m pretty able to deal with this, but one thing irritates me: it keeps me from usin
