    Hey Paul, thanks for your response and acknowledgement. I am absolutely fine putting this onto your list. For me it is just important to know, what is going on. Therefore, many thanks for the further information. For...

    Unfortunately, PaulStoffregen does not want to recieve PNs, so I post my overview here: Dismatch of set values and output times. For me it looks like an issue with the implementation in the duino-core. Here are the...

    Hi Paul, at least it looks consistent, thanks a lot! Value 64 should be out of range, since the counters (I know so far) count from 0 to 2^n-1 to access 2^n steps. On the other hand, if PJRC wants to start counting...

    Hi Paul, thank you for checking the PWM output again! I am sorry coming back to this late, unfortunately I had to check my broken washing maschine, yesterday. Your observation is really interesting. Looks like some...

    Hi Paul, thanks for your response. Well, I selected the frequency by checking the Teensy tutorial about PWM. I copied the "ideal"frequency from table 3 (section "PWM Resolution (Teensy LC, 3.0 - 3.6, 4.0, 4.1)") for...

    Hi Paul, thanks for your reply. I believe that you're right, the 74LS07 is not a good choice for my application. I will have a look at another chip from the 74-series. The transistors are slightly too slow for this...

    Hi Paul, thanks for your help. Your comment about sinking and sourcing opened my eyes, you are absolutely right. When input of 74LS07 is low, it sinks ... and LED is bright ... All right! Is it already night on...

    Hi, I started with the Teensy 4.0 (a few days ago) to build a quick and dirty camera chip tester. Therefore I am running a LED at ~2 MHz with PWM and check for intensity changes in the image output. Unfortunately, I...
