Hello, the very old timer intel 8253 and 8254 could be used in mode 1 as a hardware triggerable one-shot with programmable pulse length. Now I am using the infineon 80c167 and need a one-shot with programmable pulse length and hardware triggering too. There are a lot of counters T1 to T8 and there is the Capture/Compare unit too, but I found nothing about one-shots in the user's manua...

All, I have been handed a project to locate and obtain a replacement for a now obsolete single board computer, a win systems SAT-4DX. Win systems recommend a newer one, but there is a compatibility issue with the target hardware that the computer connects to. The target hardware utilizes the PC-104 (ISA bus) to memory map hardware into the 15-16Mb range. The new PC has a minimum of 32 M...

I hacked together my "IP cameras" using some web cams for which I was able to track down some FOSS i/f implementation documentation. This was OK for a proof of concept. But, I now have to settle on "production" hardware. There seem to be a variety of i/f's for cameras: - RS170 (requires hardware to digitize the signal; inflexible) - parallel (video is digized, just needs to be captured a...

Hi all What would be a good choice for low-end embedded hardware (single board systems à la raspi, cubieboard) with good support for USB slave mode? As in there is USB hardware onboard that can be configured to run in USB device / slave mode and there is kernel support for it; as in gadget driver. I gather this mode or something like it was / is supported on the early RasPi model

For example, suppose one has a two different boards with some overlap in software functionality and similar CPUs (same arch., different mfgr). Furthermore, these two boards have different revision levels which cause some of the functions to do things slightly differently. I've been talking...
