FspTimer: using AGT timer issues - UNO R4 Minima - Arduino Forum
Servo test program servo_timer_config: type:1 Channel: 1 Raw Period: 960000 Note: servo_timer. get_period_raw() returned a period of 960000 Which does not make sense, as I am pretty sure this is a 16 bit counter. Wonder maybe it did not like to do a period that long. So tried changing to 1500. Raw Period: 71999. Tried 750 -> 35999. Thoughts?

Tone and timer (s): when to expect interference? - Arduino Forum
The "tone (pin, frequency, duration)" command is an easy way to create beeping sounds with a connected loudspeaker. However, from the Arduino Tone Reference or the more Technical description it is still unclear to me which timers (and how many) are used. As far as I understand it now. if the same tone is played on multiple pins then multiple . . .

Which timer is used by the "Servo. h" library - Arduino Forum
The servo library uses one of the timers to trigger interrupts which it then uses to support upto 12 servos in software instead of just 2 (assumption on my part here) that a single hardware timer without additional software could support. A little bit about the servo library here -. rcarduino. blogspot. com.

Using millis () for timing. A beginners guide - Arduino Forum
Part 1 It is not usually long before new Arduino users discover that although the delay() function is easy to use it has side effects, the main one of which is that its stops all activity on the Arduino until the delay is finished (not quite true, I know, but that is usually how the problem presents itself). When this occurs the new user is usually directed to the BlinkWithoutDelay example . . .

Multiple R4 Timer Issue - UNO R4 Minima - Arduino Forum
Hardware UNO R4 UNO R4 Minima. gjacobs101 January 9, 2024, 6:07pm 1. Hello, I used Phil Schatzmanns writeup to successfully get one timer working on the R4. I tried two timers with different rates but only the first timer runs. The index from FspTimer::get_available_timer is different for each timer so it would not appear to be that.

Timers on the Arduino Mega 2560
Hi all, I am contemplating a project where I would want to have three independent timer interrupts running simultaneously and want to understand how the Arduino platform uses the timers on the Mega (ATMega 2560-based boards). As I understand, the ATMega 2560 has four 16-bit timers available and two 8-bit ones. Ideally I would like to hijack three of the 16-bit timers. My question is, I know . . .
