Wow very nice explanation, I have just started my career in embedded, when I'm searching so many videos found this... It helps a lot.. thank you so much
Information provided by you is really useful.... Too much deeply and very core information regarding internal mechanisms. Very useful for Students, Beginners, professional... Specially for person who do not have enough money to attend paid course and who have no good teacher or leader.. Thanks
I appreciate the effort being put in such a clarification of the embedded system... There are really some perfect people to teach such a perfect thing with such a perfection... uff awesome... appreciate man appreciate :::《)))
Great Video!! I got a question, if i wanted to implement three phases using the Center-aligned mode, did i have to set a seperate interrupt for the phase shift or would it be enough to just start the three timers simultaniously but with three different CCR values?
There's one slide I'm not entirely sure if it's my misunderstanding, or the chart mismatched. at 9:45 it looks like on the increasing side, OCREF is high when counter=CCR. but on the falling side, OCREF is low when counter=CCR. Did I misunderstand?
Nice video sir! and thank you for ur explanation But i can't still understand about Auto-Reload Preload Enable (ARPE). could you give me example of ARPE's purpose? Because, I've experienced setting or clearing it in debug mode but I can't see the difference , It still generates the same PWM wave form .
When you update ARR, do you want the new ARR value to take effect immediately, or do you want the ARR update to wait until the current counting cycle completes? This is controlled by ARPE bit.
They're are registers. You interface through a computer language (eg. C or assembler) and a program translates it to machine language of instructions. These registers just are just memory locations that can be written in assembler or C language. Placing data values in these memory correspond to giving values to ARR and CRR.
for stm32F103 mainly there are 4 independent pwm(timer port). you can setup how ever you want. every port has 4 output that have same counter values but different output forms.
nice video, you have the book Embedded Systems with Arm Cortex-M Microcontrollers in Assembly Language and C(second edition) Can you pass this book to me? please
