Voor mijn verjaardag , nieuw speelgoed gekregen !
De Icom 9700 is een V/U/SHF trx all mode en wat voor mij belangrijk is , is de mogelijkheid om satellietwerking te doen .
Tevens zit er 23 cm op en dit kan later nog van pas komen bij het ADSN werk.
Uitbreiding van mijn SHF materiaal.
Af en toe , en als ik de kans krijg, breid ik mijn SHF spullen uit.
Wanneer de kans er is , moet je eigenlijk niet twijfelen , want ze worden zeldzaam.
Het kleine grut is goed tot 18 GHz
Volop terug in de software.
Mijn rotorbesturing werkt tot volle tevredenheid, maar er zijn nog twee probleemkes die ik opgelost wil zien :
1. De afhandeling van de TCP verbinding bij afsluiten .
2. Tijdens de rotorsturing kan ik niet de actuele positie terugsturen via TCP , dit komt omdat alles zich maar in één draadje ( thread) afspeelt , namelijk in de main.
Dus , ik ben nu aan de studie voor multithreading onder C .
Dit lukt aardig op mijn Intel/AMD machine voor een simpel programmaatje maar de RPI heeft een ARM processor en ik wist niet of er een library is voor die processor.
Na wat gezoek ( er is niet zoveel te vinden over multithreading met de RPI 4)
heb ik gevonden welke lib ik moet installeren in de RPI:
sudo apt-get install libpthread-stubs0-dev
Dankzij :https://gist.github.com/pvrego/7fd2610d0bf5ca063e63db6ab776e89c
Wat ge dan nog moet doen , is bij het compileren de volgende parameter meegeven in de syntax:
gcc -Wall -c -pthread "%f". ( Dit komt uit de Geany IDE)
Het is de -pthread dat belangrijk is !
En deze header insluiten in uw programma :
#include <pthread.h>
En ge kunt starten
Hieronder een klein voorbeeld van multithreading.
*******************************************************************************
#include <stdio.h>
#include <unistd.h> // posix library
#include <pthread.h>
void* myturn (void * arg)
{
for(int i=0;i < 8;i++)
{
sleep(1);
printf("My Turn ! %d\n",i);
}
return NULL;
}
void yourturn ()
{
for(int i=0;i < 3;i++)
{
sleep(2);
printf("Your Turn ! %d\n",i);
}
}
int main(int argc, char **argv)
{
pthread_t newthread;
pthread_create(&newthread , NULL , myturn , NULL);
yourturn();
pthread_join(newthread , NULL);
pthread_exit(NULL);
return 0;
}
en het resultaat:
en dit gebeurt er als de code niet juist is , m.a.w. geen threads.

Een nieuw begin brengt altijd gedachten naar boven .
Ik heb eens gekeken welke zo de " hot" topics waren de laatste 12 maanden en ook sinds de start van deze blog
12 maanden :
Weerbalonnen waren erg in trek , dan een reparatie van een TS440S en op 3 een vleermuisdetector , raar
Sinds de start:
Hier is vast een liefhebber van de schepen regelmatig aktief , gevolgd door de data van de Amroh 402 spoel en een verwijzing naar Websdr's
