I'm running an ATMega88A at 8MHz and have the SPI configured to run at Fosc/2 = 4MHz.
In theory, shifting out 5000 bytes over SPI should take 1/4000000 * 8 * 5000 = 10ms. But according to the internal timer, it's taking just over 19ms. This seems like a ton of overhead. Is this typical?
I'm laying out a PCB for a NiMH single AA cell charger following the AVR450 Application Note - Battery Charger for SLA, NiCd, NiMH and Li-Ion Batteries but I'm not sure where to place the NTC thermistor that will read the cell temperature throughout the charging process.
I plan to lay out the ce...
@NickAlexeev yes, I was thinking about it but I didn't take it in the end. I have an 18 credit semester as well as being the lead project coordinator for my universities IEEE branch. three of my six classes are project classes so I'm pretty busy
@Funkyguy I was going to ask about your impression of course. I couldn't take it this fall either. I've talked to the professor, though. He said that this is not the first time that this course is offered, and probably not the last.
