Beispiel "PWM_BASIC" der Lib ATtiny_PWM wird nicht kompiliert

harry-th · December 31, 2023, 5:16pm

Hallo,
ich versuche gerade, auf einem ATTiny412 das Beispiel PWM_BASIC aus der Library ATtiny_PWM zum Laufen zu bringen.
Den ATTIny412 verwende ich wegen notwendiger pinout Kompatibilität (VCC, GND) in einem existierenden PCB Layout
Meine Umgebung:
Arduino 1.8.13 ( wegen Benutzung von megatinycore)
Library ATTiny_PWM installiert
ATTiny412 in Programmieradapter
UPDI-Programmieradapter mit FTDI USB to serial adapter und RX/TX to UPDI Schaltung

Hier der code:

float frequency = 1000.0f;

float dutyCycle = 0.0f;

void setup()
{
  Serial.begin(115200);

  while (!Serial && millis() < 5000);

  delay(500);

  Serial.print(F("\nStarting PWM_Basic using PWM on "));
  Serial.println(BOARD_NAME);
  Serial.println(AT_TINY_PWM_VERSION);

  //assigns PWM frequency of 1.0 KHz and a duty cycle of 0%
  PWM_Instance = new ATtiny_PWM(pinToUse, frequency, dutyCycle);

  if ( (!PWM_Instance) || !PWM_Instance->isPWMEnabled())
  {
    Serial.print(F("Stop here forever"));

    while (true)
      delay(10000);
  }
}

void loop()
{
  // You can change frequency here, anytime
  frequency = 2000.0f;
  //frequency = 20.0f;
  dutyCycle = 20.0f;

  PWM_Instance->setPWM(pinToUse, frequency, dutyCycle);
  analogWrite(PIN_PA3, dutyCycle * (1 << 8) / 100);

  delay(10000);

  analogWrite(PIN_PA3, dutyCycle * (1 << 8) / 100);

  //while (1)
  delay(10000);
}

Die einzige Änderung, die ich gemacht habe, ist

#define pinToUse PIN_PA5 -> #define pinToUse PIN_PA3

Vielleicht stehe ich nur am Schlauch und es ist nur eine Kleinigkeit, denn ich kann mir nicht vorstellen, dass da in nicht lauffähiges Beispiel mit der Lib ausgeliefert wird, aber ich komm nicht weiter und bitte höflich um Erleuchtung.

Hallo,

Link zu deiner Lib?
Ohne Pin Änderung kompiliert es?

fony · December 31, 2023, 5:34pm

Bei der 1.8.19 kann man auch das installieren, nicht das die veraltet ist

StefanL38 · December 31, 2023, 7:58pm

IDE so einstellen.

Wenn es das auch auf deutsch gibt bitte link posten.
Hab danach gesucht bin aber nicht fündig geworden

fony · December 31, 2023, 8:05pm

Meinst das hier?

Guten Rutsch

Das Programm passt schlichtweg nicht in den Speicher vom 412er... (Steht auch in Deiner Fehlermeldung: arduino_build_680113/PWM_Basic.ino.elf section .text' is not within region text')

Wenn man den Code in der loop() Auskommentiert und in der setup() sämtliche Serial Zeilen ebenfalls, verbraucht das Programm schon

Es wäre wohl empfehlenswert diese Lib nicht zu verwenden und das PWM zu Fuß zu programmieren.

Und da passt noch etwas nicht. In dem Code den Du gepostet hast, ist BOARD_NAME nicht definiert.

Hier findest Du Beispielcodes zur PWM Programmierung:

github.com

SpenceKonde/megaTinyCore/blob/master/megaavr/extras/TakingOverTCA0.md#example-2-variable-frequency-and-duty-cycle-pwm

# Reconfiguring a Type A timer (like TCA0)

We have received many questions from users about how to take over TCA0 to generate 16-bit PWM or change the output frequency. There are a few non-obvious complications here, and this document aims to clear up these confusions. First, before you begin, make sure you have a recemt version of megaTinyCore installed. This document references functions added in the 2.3.x versions; pre-2.x versions further contain significant differences that render much of this document inapplicable. What is written here largely applies to TCA1 on the AVR Dx-series parts, and is expected to apply to the AVR EA-series as well, though no definitive information on those parts beyond their mention in the AVR EA-series technical brief has been released. It it unlikely that any relevant changes will be madem but not impossible.

## For far more information on type A timers
Microchip has made available a Technical Brief describing the capabilities of the Type A timer, which is arguably the most powerful timer available on modern AVR devices (it's this or the type D timer, but while that is unquestionably more complex and is capable of some tasks which the TCAs are not, it is applicable to significantly fewer use cases, and far more challenging to configure). That technical brief describes all applications of the type A timer, not just PWM (and also assumes it is starting from power on reset (POR) state; if you are using code from there, you can call `takeOverTCA0()` or `takeOverTCA1()` to both reset it to this state, and ensure that the core does not subsequently mess with it).

[Technical Brief 3217: Getting started with TCA](https://www.microchip.com/en-us/application-notes/tb3217)

## Reconfiguring TCA0 while using DxCore and megaTinyCore
The most common point of confusion is the fact that DxCore and megaTinyCore, out of the box, configures TCA0 (and TCA1 if present) for use in "Split Mode" - this allows them to generate 6 8-bit PWM signals each. Since analogWrite() only supports 8-bit PWM anyway, when using the Arduino API functions, there is no loss of functionality imposed by this.
However, for users wishing to take over the timer, it has caused confusion, because it changes the behavior of the compare and period registers significantly (they are treated as 8-bit values instead of 16-bit ones), and TCA0.CTRLD which controls split mode is enable-locked. In order to help resolve this issue and make it easier to make use of the advanced functionality of the timer, we provide the `takeOverTCA0()` function. That will disable all of the core-mediated API functionality that interacts with the timer, so that digitalWrite (and analogWrite) will not reconfigure the timer, which could result in PWM on an unexpected pin being turned off(in the vase of digitalWrite - you should not call analogWrite() on a pin that is controlled by TCA0 anyway after taking over TCA0. Simply calling `takeOverTCA0()` will perform a hard reset of the timer in addition to instructing analogWrite() and digitalWrite() not to configure that timer (digitalPinToTimerNow() will return NOT_ON_TIMER for TCA0 pins).

### Fully manual reconfiguration
You must disable the timer when switching split mode and non-split mode, and Microchip recommends that you issue a reset command. That's what we do here. This will reset timer registers to their default (not our default) values. Note that in split mode, the two low bits must be 1, or the command is ignored. Only 00 (none) and 11 (both) are listed as valid; it sounds like there had originally been a plan to allow the RESTART command to be issued independently to the two halves (and possibly a third command) but that it either was never implemented, or never worked correctly and was discovered early enough and dropped instead of adding another issue that would go unfixed for 5+ years to the errata.
```c++
  TCA0.SPLIT.CTRLA=0; //disable TCA0 and set divider to 1
  TCA0.SPLIT.CTRLESET=TCA_SPLIT_CMD_RESET_gc|0x03; //set CMD to RESET to do a hard reset of TCA0.
```
Note that as these bits have the same function in SINGLE and SPLIT mode, it does not matter whether you reference them as TCA0.SINGLE.* or TCA0.SPLIT.*

Wahnsinn das die Lib für etwas PWM soviel Speicher braucht. Vor allem da die ATTinys ja eher die sind, die weniger davon zur Verfügung haben.

ich danke euch allen für die guten Tips.
Ja, es ist schade, dass diese Lib soviel Speicher verbraucht und ich werde wohl dem Rat von Kai-R folgen, und die PWM zu Fuß programmieren, da ja auch noch zusätzlicher Code für die geplante Funktion benötigt wird.
Zur info für euch:
Ich habe eine LED Deckenlampe gekauft, die über eine Fernbedienung in Helligkeit und Farbtemperatur eingestellt werden kann.
Leider mußte ich feststellen, dass die Lampe den eingestellten Zustand vergißt, wenn man sie über den Lichtschalter ausschaltet.
Ich habe dann das Netzteil analysiert und festgestellt, dass da anscheinend ein kundenspezifischer Chip verwendet wird. Den will ich ersetzen und der ATTiny412 passt genau ins Layout.
Das Einlesen der FB-Codes funktioniert schon und jetzt fehlt eben noch die Ausgabe von 2 PWM Signalen (4kHz, 8% -100%), da die Einstellung der Farbtemperatur einfach über die unterschiedliche Ansteuerung von 2 verschiedenfarbigen LED-Ketten erfolgt.

Nochmal vielen Dank
