In this video I set Clock Configuration tab → HCLK (MHz) to 72 You can set the speed of STM32 to any value you want up-to maximum of 72 for STM32F103C8T6. Most of the time 72 is better. I set prescaler to 71 The reason is I needed to measure micro-seconds for the sensor Time = 1 / Frequency 1 us = 1 / 1MHz To have micro-second, timer frequency needs to be 1MHz. Because I already set clock to 72MHz, I need to divide it by 72 for timer frequency. You can divide it using prescalor Prescalor is always one less so it is 71 Another example: If you set clock to 64MHz, you need to divide it by 64 for timer frequency. Prescalor is 63
I am doing this project on STM32F401RE.the code runs fine but when i debug it shows me the error. Error message from debugger back end: Error erasing flash with vFlashErase packet.
how to debug on keil C, power supply from ST link is 3.3V so when plugging in 5V pin on stm32 the voltage is only 3.3V, so hcsr04 module not working, please help me
@@NizarMohideen I power separately for Hc Sr04 module, power stm32 via STlink and then connect to common ground, will my computer be damaged when supplying 2 sources at the same time? I'm a newbie
The computer will be fine as long as you supply 5V or less to any sensors. For more information about safety, please watch video no 51 or 52 in my TH-cam channel th-cam.com/video/Ga2lfBq9zaE/w-d-xo.html th-cam.com/video/TeAa6UPIb-c/w-d-xo.html

I set prescaler to 71
The reason is
I needed to measure micro-seconds for the sensor
Time = 1 / Frequency
1 us = 1 / 1MHz
To have micro-second, timer frequency needs to be 1MHz.
Because I already set clock to 72MHz, I need to divide it by 72 for timer frequency.

Prescalor is always one less so it is 71
Another example: If you set clock to 64MHz, you need to divide it by 64 for timer frequency.
Prescalor is 63
nice work thanks so lot for your hard work
Thanks to you
Thank you so much, it worked for the STM32-L476RG, I just had to change #include "stm32f1xx_hal.h" to #include "stm32l4xx_hal.h" on the libraries.
Thank you, Nizar
Always welcome

Es Koo run krtaa ha aur stm board par transfer krta ha too nehe hota kata ha stm link is not recognize kindly help
i love you

Before connecting st-link, supply 5v via usb.
Or, you can connect 5v (vcc) and gnd to +/- of separate 5v source

Sir one request can you plz interface ultrasonic sensor with smt32 to control the brushless motor, if you have code plz send me
I am sorry I don't have a brushless motor with me at the moment
Ok sir
Can i get hex file of this Project?plz
I am sorry. I don't have the hex file with me
You can make one using STM32CubeIDE
