Hello, I would like to know if it is possible to help me? Is it possible to add a variable allowing to vary the reading speed? Like a pitch for example? And also to be able to do reverse playback ? Thanks for your help.
@@mutexembedded2206 ok sir, But i don't think UART can achieve sufficient baud rate to transfer audio data. so it will be helpful for me if you can guide me for USB. How can PC save file from USB. Thank you.
Salam Mohammed Ramadan Karim can you tell me please , how can i change timer period of timer-Interrupt while running the Code(from While-loop)? I tried to change the value of the period from the while-loop with this line(TIM2->ARR = 25; ), but the LED blinks (with delay) just for 3-4 clicks und stops . can please help me, i will be very gratfull thank you
Nice Tutorial! One question, how can I calculate how much RAM is used when reading/streaming the WAV file? I was wondering if you could stream the WAV file and do other stuff at the same time.
@@mutexembedded2206 interesting, is there any way to calculate buffer size? I imagine it's something based on the WAV's properties that you select on the conversion.

I just changed MODE_ANALOG => MODE_ANALOG1, in CS43_MODE enum and it solved the issue. Is it correct Mr Yacoob? //1. Mode Select Enum typedef enum { MODE_I2S = 0, MODE_ANALOG1, }CS43_MODE;
Hi, my audio is not playing although led status is changing properly on pause/resume and start. Mounting/Unmounting led status is also toggling properly. Even i removed my wav file from pendrive it still status led working on pause/resume and start.

Actually , I have a problem , probably you can help me with , I m trying to read wav files as you did with the usb storage , this time I m trying to do it with sd card module that works with spi , the code works fine ...it reads the wav file ...but ...I hear nothing...
Hi Mohamed, I copy the code exactly as you detail in the video and the first led shows the correct connection of the USB but seems that never enters the second loop where the USB drive is read... do you have this problem in the developing stage? Thanks for the support
Can you debug and find out where exactly it got stuck. Tip: check you USB fread/fwrite functions first to ensure your FatFs is setup correctly in the first place
Hi@@mutexembedded2206 where it got stuck is in the line137 - if(Appli_state==APPLICATION_READY) as the Appli_state never changes from APPLICATION_START to APPLICATION_READY therefore never even use the f_mount function (as not get into that loop). From that line then start the while (1) again.
@@mutexembedded2206 Hi Mohamed I've been trying and the problem seems to be the VBUS as the PC0 was not activated (I've to do it by myself in CubeMX) now the LED's are correctly working.
The problem now is that I cannot get any audio output from the USB... can you please detail in which buffer is stored the data from USB in order I can check it in the debugging mode?

Got lots of new tutorials for you later this year.
Thank you. these tutorials have been so helpful from me learning the stm32. can you do something with LabVIEW and stm32
Good afternoon! Thank you for your video and tutorials.
Thanks a million. That's a great explanation.

Perfect tutorial. Thank you. Do you have a advanced knowledge about RTOS? I looking for a video tutorials.

Yes, perhaps through USB or UART

Using auto reload is the way to change timer period. But need to ensure you are doing it right.

Nice Tutorial! One question, how can I calculate how much RAM is used when reading/streaming the WAV file? I was wondering if you could stream the WAV file and do other stuff at the same time.
RAM usage is the circular buffer size only. Yes you can have CPU does other things too, can use RTOS for multiple threads
@@mutexembedded2206 interesting, is there any way to calculate buffer size? I imagine it's something based on the WAV's properties that you select on the conversion.
Sir,
Please give a code for recording and play wav file without using audio codec
You can direct Audio to Analog output instead of I2S

can you provide videos for ri2s slave role transmit

Hey , can i ask a question
Salam,
Yaqoob i was watching your ENC28J60 3 year old video. I did not find your last part. is it missing or you haven't made it. Jazakallah.
No missing video in this channel. th-cam.com/video/A4c0nJudOI0/w-d-xo.html
Hi Hasan,
I stopped working on that, I was at Uni. I am planning to make a better series about STM32 Ethernet
If you look at my notes under the ENC208j60 I managed to get iENC28j60 to work using the arduino libraries and posted the code to github. Even easier now if one is using an eclipse based IDE like SW4Stm32. This has a button called convert project to C++. Then one can directly use the arduino libs with minimal modifications. Better is to use one of the supported PHY chips on a board that supports a PHY.
awesome
