are the 50hz chips manufactured at 50hz ? or are they downclocked to 50hz. why cant you use higher clocked speeds ? like even 500 mhz, etc ? is there something

are the 50hz chips manufactured at 50hz ? or are they downclocked to 50hz. why cant you use higher clocked speeds ? like even 500 mhz, etc ? is there something special about 10 and 50hz ?

That's the number of times per second the main update code runs and it has nothing to do with the number of clock cycles or instructions per second the CPU can run (other than the fact that the chip needs to be fast enough to have the update code finish before the next time it needs to start).

  Exactly this. A chip running at 50hz would never be able to run a task 50 times per second when it's only executing 50 instructions per second.

  ah thanks! that makes it so much clearer.

If I understood it correctly, they’re not talking about a chip literally running at 50Mhz. They’re talking about polling a sensor in a loop running on a 50Mhz timer. The processor doing that is certainly running at a much higher clock frequency

  To clarify, its 50Hz not 50MHz

    and 50hz = 0.02s

  Yeah they're talking about the control loop itself which means 50 times a second the computer/program looks at it's inputs (sensors) and changes it's outputs (commands to actuators). The actual computers processing that program run much faster.

Chips have internal timers which can be configured programmatically so they emit hardware interrupt in specified time intervals. When the interrupt is emitted, CPU jumps to the method which executes the certain program. After that it goes idle, waiting for the next cycle.

  The greatest Joy in my life today is that i have been cured of Herpes by a Doctor called Dr. Macaulay , I was infected with HERPES Disease in 2019, i went to many hospitals for cure but there was no solution, so I was thinking how can I get a solution,so that my body can be okay. Until one faithful day as i was browsing on the internet I saw a testimony on how Dr. Macaulay has helped people in curing Herpes and other diseases, quickly copied his WhatsApp number so i contacted him for solution for my Herpes disease, So Dr. Macaulay told me that his going to prepare his herbal medicine for my health which he sent to me, luckily after 2week my Herpes was cured. Dr Macaulay is well recognize as one of the best herbalist doctor in Africa, you don't have to be sad anymore or cry anymore on this disease when the cure is available. .For enquiries:Via:Dr.Macaulayherbalhome@yahoo.comWhatsApp: (+2349067522465)https://wa.me/message/HJO6BWJEP4CFJ1 https://wa.me/message/HJO6BWJEP4CFJ1
