The Raspberry Pi in all its invocations was conceived as a filip for education about computer systems but looking at some of the recent posts in these NGs, it seems to have got stuck in a blind alley; the alley of Linux, whereas the real...
Hallo! Die Vorgeschichte: ich restauriere gerade einen Eurocom-1-Rechner von Eltec aus dem Jahr 1979. Der hat einen 6802 @1MHz, 2kB EPROM (2716), 1kB RAM (2* 2114), zwei 6820, einen 6850 sowie 30 Tasten und acht Siebensegmentanzeigen auf...
EETimes had an interesting article asking if 4-bits was dead.These chips have been pad limited for 2 decades, and as such areprobably manufactured at fabs that are beyond obsolete.You could take a public CPU design like OpenRISC and replace...
What's the fastest periodic IRQ that you have ever run?We have one board with 12 isolated LPC1758 ARMs. Each gets interruptedby its on-chip ADC at 100 KHz and does a bunch of filtering and runs aPID loop, which outputs to the on-chip DAC....
The TI MSP430 looks like an interesting chip. The low poweroperation allows 16 bit adc onchip. Now they seem to be doing thesort of things that microchip did in the past such as free seminarsand low cost development tools. Like most...
Hi all,I'm looking for ideas as to what features should be included in a newembedded CPU architecture. What are current microcontrollers missing?All suggestions greatly received!Cheers,JonB
