Today, 18:01Hi, "min operating current" means the shunt reference diode needs a minimum current to work properly. Letīs say: * the Ref datasheet says:...2 replies | 15 view(s) -

Today, 15:50KlausST replied to a thread rectifier protection at high frequency high frequency from high voltage transients in Elementary Electronic QuestionsHi, my answer is: No. Btw: for the simulation... the "Transient Spike" should be in series to the "Supply", not in parallel.

Today, 15:48Hi, With my designs Iīm used to keep errors very low. I usually try to keep it as low as possible. Here - with the correct use of the...18 replies | 470 view(s)

Today, 14:31Hi, Iīd always rely on hardware over software. The Microcontroller has the periferal to get perfect timing down to one clock cycle. It just may...18 replies | 470 view(s)

Yesterday, 09:28KlausST replied to a thread Feeding DMM with 5V source instead of batteries. in Elementary Electronic QuestionsHi, I agree. Thus I recommend to use an DCDC converter to get high impedance isolation. Klaus5 replies | 137 view(s)

Yesterday, 09:26Hi, You may use the interrupt, but thereīs no need for it. Read the datasheet: Iīm about sure you may wirte to the OCRx registers at any time,...5 replies | 105 view(s)

Yesterday, 08:10Hi, It depends on configuration...and I didn't go through your setup.... But with OCRx registers for PWM you don't change frequency, you change...5 replies | 105 view(s)

18th January 2019, 11:31Hi, The value is "true RMS"? Use a scope to check amplitude and waveform. If the amplitude drops, it is cause by the drop in the triac. ...23 replies | 619 view(s)

18th January 2019, 09:19Hi, The problem is: we can not know what XTAL you use. We can not read the datasheet as long as you don't give (a link to) it. Each pin of...10 replies | 291 view(s)

18th January 2019, 08:24Hi, 33pF for a 20MHz seems (to me) a bit high capacitance. What does the XTAL datasheet say? And how much I/O capacitance has the clock...10 replies | 291 view(s)
