Hi, there I'd like to know is there any specific part designed for power line communication "over DC".Something like, https://www.yamar.com/datasheet/DS-SIG60.pdfI've searched a bit, seems that most manufacturers provide PLC over AC solutions.Any id...

Hi, there, I am not sure this is the right place to ask if it's concerning IDE.Just got my new STM32H747 Discovery kit, running CubeMX examples,All running well, except for debugging:(I am using MDK Keil (V5.27 / V5.28) and on-board STLink V3)I found...

Hi, there!  I've just downloaded the STM32H747I-DISCO MB1248 board design files(https://www.st.com/resource/en/board_manufacturing_specification/mb1248_bdp.zip) I found that the schematics is an Altium Designer Project, but layout is an Allegro brd ...

Hi, dear all!I am curious about the current functionality of FOC SDK.I checked that in ST Motor Control Workbench does support over voltage protection and a brake resistor can be used to dissipate the power.But I am curious about whether or not the ...

Hey, after taking a further look on the map file, I just found that the when using newer CMSIS DSP call a sqrtf function which lies in FLASH-ITCM region, not ITCM! 0x0020212c 0x0020212c 0x0000003a Code RO 2750 i.__hardfp_sqrtf ...

perhaps not using Chinese in the path?

Okay, I am so silly, I need to turn off the cache.  The default cache policy for SRAM is write-back, so the up-to-date data is still in cache not in the SRAM. Same for other cached data.

Thanks for the reply, Hani!Have you ever tried this generator mode using ST's FOC library?

Newer CMSIS DSP has huge impact on ITCM-Ram execution!!

Strange problem when using Keil and debugging STM32H747 Discovery. Concerning RAM address

Why STM32H747I-DISCO ref design using two different CADs?

Does ST FOC SDK support generator mode?
