Re: How to use gpio clock

That depends on how you are setting up the PWM registers. Could we have your assembler for the PWM registers? .section .init .globl _start _start: b main .section .text main: mov sp,#0x8000 /*Configure GPIO18 as PWM0 output, which is ALT Fun 5 setting in the register 10b=2 decimal*/ mov r0,#18 mov ...

Re: servo motor programming in assembly language

yes. my doubt is how to assign gpio clock and how to generate pwm signal for servo. i red about the registers from the datasheet but i have no idea how to use it The code below shows how to use the Pi's PWM to drive a servo motor. This may be a good start point. https://github.com/boochow/bare_mata...

Re: servo motor programming in assembly language

wether i need to assign gpio clock to use pwm ? Yes, you have to. And, as far as I know, the register addresses for PWM clock are not clearly documented in the BCM2835 peripheral manual. You can find them in https://elinux.org/BCM2835_registers#CM_PWMCTL . Then of course you have to set up the PWM ...
