Making Fatal Hidden Assumptions

We often find hidden, and totally unnecessary, assumptions beingmade in code. The following leans heavily on one particularexample, which happens to be in C. However similar things can (anddo) occur in any language.These assumptions are...

12V-LED-Kfz-Birnchen CAN-Bus

China bestellt. Bei beiden wird in der Beschreibung hervorgehoben, dass es zu keinen Fehlermeldungen im OBC und CAN-Bus kommen wird. Bei den kleinen Dingern steht sogar CAN BUS auf der Platine. cu. Juergen -- \\\\\\\\\\\\\\\\\\ ...

CPU design

For implementing the higher level protocols for my Spartan 3E starter kitTCP/IP stack implementation, I plan to use a CPU, because I think thisneeds less gates than in pure VHDL. The instruction set could be limited,because more...

Tiny AVR

We need a small chip with absolutely lowest power, so for the attiny4:Top of the spec stated 200uA at 1MHz, but nothing about 125KHz.Bottom of the spec has some chart of around 30uA at 125KHz. Can thisbe trusted? If so, why don't they say...

4 Bit MCUs, Still Alive and Kicking?

I'm not sure which group it was in, but someone who designs toys talked abo ut the extremes they would go to for cost reduction, removing useful, but n ot essential resistors because they were $0.001 each. I'm trying to find out if there...
