IS IT POSSIBLE TO IMPLEMENT THIS ON MULIPLE ADC CHANNELS? I AM USING FOR SING CHANNED BUT FAIL TO IMPLEMENT ON MULTIPLE ADC CHANNEL..

the repository is not public

nice tutorial, hello from Ukraine

Excellent video! Thank you.

Thanks for the video and a great tutorial. Could you do a video on how we use stm32 to make USB microphones? I would like to connect two or more microphones and record the multichannel sounds.

hey I have one doubt I want to connect more led stripes in parallel then i want use the different timer pwm but I have problem in the configuration DMA request another timer dma does not show that dma trigger option But I will change the code like that but my code run only single timer In my main c this for tim 2 reset_all_leds(leds, NUMBER_OF_LEDS); HAL_TIM_PWM_Start_DMA(&htim2, TIM_CHANNEL_3, (uint32_t*)leds, NUMBER_OF_LEDS1 * 24 + 24); HAL_Delay(300); set_all_leds(leds, NUMBER_OF_LEDS1); HAL_TIM_PWM_Start_DMA(&htim2, TIM_CHANNEL_3, (uint32_t*)leds, NUMBER_OF_LEDS1 * 24 + 24); and this one is same code tim 3 led_pos_counter++; if(led_pos_counter == NUMBER_OF_LEDS) { led_pos_counter = 0; } temp_neo_pixel = circular_pattern_led[led_pos_counter + NUMBER_OF_LEDS]; circular_pattern_led[led_pos_counter + NUMBER_OF_LEDS]; circular_pattern_led[2* NUMBER_OF_LEDS]; HAL_TIM_PWM_Start_DMA(&htim3, TIM_CHANNEL_1, (uint32_t*)&circular_pattern_led[led_pos_counter], NUMBER_OF_LEDS * 24 + 24); HAL_Delay(100); circular_pattern_led[led_pos_counter + NUMBER_OF_LEDS] = temp_neo_pixel;

YOU ARE THE LIFE SAVER

Excellent job man.

Here is a note in datasheet, `Low Byte of Gyroscope Y-axis data. To convert the output of the gyroscope to angular rate measurement use the formula below: Y_angular_rate = GYRO_YOUT/Gyro_Sensitivity` What is Gyro_Sensitivity ?

11:17 can you explain more about reg MAG_DATA_ONSET? why read 8 byte in that? many thanks!

Thanks a lot! what is the rest of line 106? printf("frequency %f: %f ", ((float32_t)(i * SAMPLING_RAT) / FFT_LENGTH), out...

Nice video,great explanation

Great Job. How do I get to interface mpu6050 with stm32 so that I only get readings anytime there is an interrupt coming from the interrupt pin of the mpu6050 when there is linear or rotational movement?

Thank you for the video and a great tutorial. If you don't want to remove the microphone from the board then switch to I2S3 instead and follow the tutorial. The recordings will be done without any hassle :)

Do I need to solder with Nucleo-L412KB? Also how would I if I need to. Thanks.

I got error " undefined reference to 'arm_rfft_fast_init_f32'. I imported the DSP library as you mentioned in the other videos. Why i am stille getting the error?

How to store structure data to eeprome and read back

nice work. can i get all the files and code for your all videos when i join to steppeschool or i need to jion through patreon. which one i need to choose. cammant your answer please. i really like your videos and excited to making it my own.

what is the perpose of filter out variable

Great Explanation!

Hello Stepp School. I have everything setup as explained, yet im never able to enter the callback, i feel i have followed everything, do you have any idea as to what could be the reason as to why my callback is not working? I have enabled IT on my timer, i have run the HAL_TIM_Base_Start_IT(&htim2); and i have created a callback function with some actions to take during the interrupt. All i have in my main loop is a delay, and its just stuck in there, the interrupt never fires.

Thank you for this video. It saved me lot of time. Can I also ask how to detect the event of disconnecting the USB cable? Otherwise, in such event, the output buffer keeps playing with no new data coming which makes annoying sound.

Thanks!

When i am copying hal_statustypedef in another c file then it is not coming as Library function , hal_ok is also coming as simple line not as function. Can you please help me why it is happening . There is syntax error coming.

Excellent work please tell me the motor voltage rating & rpm rating and torque and max current , also size of wheel diameter, in short please give the links for motor & wheels of pololu

Hi, what is your main code? I've copied all the code you showed in the video, but I get no audio.

Hii can you use stm32f030 to read ppm and work with servo pwm?

I figured that diff gain also increases response speed to perturbations of the motor speed, so that it may be possible to reduce the P gain... In your demo, it seems that you are showing the response from an uncontrolled state to a controlled state, rather than response to a perturbation of the load? Or? But, I'm just some old guy, who never did learn the mathematics part, more of a "hands-on" and conceptual driver.... 😀

It would be interesting/useful, to show, on the graph of the motor speed, the PWM value that is applied, so that we could see the action of the differential and proportional functions make the quick response of the PWM, and the slower changes due to the integral part... Hmmm... Possibly also show the values of each of the three correction terms? But, maybe that's in the next video?

I am not sure but I think your convolution formula should be y[n]= sum of (x[n-k] x h[k]) with k=0 to k=N ( N order of the filter). not sum of(x[n-k] x h[n]). I am sorry, I may be wrong!

Nice!! a lot learned!

Pay to play... I guess it's a way of getting actual income for the work

Looks like nice way to handle "edge conditions".... I haven't read the timer information, yet, so I was surprised to see overflow on such a low speed operation. Thanks!

Hello, thank you for your video, but i have a major problem, when i go to debug configurations and try to enable the SWV, i can tick the option... would you have an idea about how to resolve this problem and why it occures ?

Trace become disable while debugging , what to do?

Hi, how did you calculate the Covariance matrices?

Filter coefficients are initialized from double literals and casted to float32_t. Assuming float32_t is float this should give warning

Best tutorial for the printf() function in STM32 IDE I have found! I love how easy the setup was and it worked on first try. Some note for all who want to use it: You can create new .c files and use the printf() function. Just make sure you add #include <stdio.h> because only then the printf() function is declared.

This is really useful. I've gone through the difficulty of using external EEPROMs to hold calibration constants and offsets for my STM32 projects, but the method you show is much more convenient. Thank you!

In other words - the same what you obtain in SWV window (same kind of saw) I would like to see on the oscilloscope. What more I should do ?

Hello nice work! i like your video very much, but i cant find the code, i am already accessable to your web page, please advise the website to your code...thx

Nice work!

Thank you! Your videos are always informative and unique!

3:52 why it get 6?

Which is better Kalman or Complementary filter? For orientation estimation

I think HAL_TIM_IC_CaptureCallback is wrongly mentioned as a fn which calculates the pulse width. It just detects the rising and falling edges of the PWM signal. You need to change its CCER Register Value to make it detect the signal

Very, very helpful. Thank you. But there is also one thing interesting for me. How connect TIM1 to pin, for example pin PA8. I would like to see signal on oscilloscope.

Why did you disable the clock source? In my case, I am using an external oscillator to generate the system clock. However, I'm not finding an option to select the external clock as the source. What should I do in this situation with cubeMX tool?

Great explanation!

Can you share your libary cs43l22? Thank you.
