Someone in another group is thinking of using a portable assembler to write code for an app that would be ported to a number of different embedded processors including custom processors in FPGAs. I'm wondering how useful this will be in writing code that will require few changes across CPU ISAs and manufacturers. I am aware that there are many aspects of porting between CPUs that is ...

Hi Folks (and pardon me if I'm not on topic)- I'm looking for a way to synchronize some code activity to the Android display frame rate. It's a short bit of code that will simply set the color of a small display region, nothing more. Is there some sort of method or hook that I can exploit for this purpose? I can use a timer running at very fast intervals successfully but the renderin...

Used .id_table instead of .of_match_ta

Got curious after a question on EmbeddedRelated.com -- is there a unified SBC market, or is it totally splattered? 20 years ago if someone said "industrial SBC" then there was probably a PC-104 board in the mix, and if they said "military SBC" then it was probably VME. I'm wondering if that's still the case, or if the world has been taken over by BeagleBxxx and XXXX-Pi boards. Hard ...

I want to push a bit stream through a series of *identical* devices and have (identical) software running on each determine if that particular device is being addressed, or not. It seems like the simplest way to do so is to require each device to examine an address field in the packet and, if '0', assume the data that follows is intended for its consumption. If not, decrement the address ...
