Hi,i just tried to see the reaction on some events on a system with H7A3 cpu and was surprised:EXTI response time was 50 us ! This is a lot for a ARM cpu running at 200MHz - too much, i would say.ED: wrong timings measured, my error : pins have cer....
Hi Sir , I need your help with some questions about SPWMI:1. STM32Cube_FW_H7_V1.7.0 without Demo project, Could you provide a Demo project of SWPMI STM32H7？2. As RM said，SWPMI can serve only as Master interface, Whether SWPMI can communicate with ...
Hi to all.I have an H-bridge motor drive that I'm having some EMC issues with. There are always conflicting requirements. I want to drive the FET's hard , for power dissipation reasons , but faster gate rise times mean higher harmonic frequency gener...
You can see my codeThe 'send_frame' / 'CAN_CMD_STD' functions are about CAN bus transmission.Removing 'CAN_CMD_STD' code will make all my code work. In particular, the 'data_set1' array can contain appropriate adc values.But if I add 'CAN_CMD_STD' co...
Hi I am working on SBSFU Application project from STM32U585 project. I have done below changes to the existing project.1. Added my project code SBSFU_Appli_NonSecure project.2. Previously this project was assigned 192KB and it was hardly using 3% of ...
Hi all, I have already searched on the forms and in general did not find an answer to my problem, I will be very grateful to you for help.I need to create an output signal with a frequency of 100 Mhz as CLK in STM32H745. I used the Discovery Boards ...
Hi, i have write a code to erase data of internal flash memory of the MCU. But when i debug it,a page(tab) pops up with the following message: No source available for "<signal handler called>() at 0xfffffffe" . And i can't any longer debug. I use th...
STM32H745 datasheet says:RTC_OUT can come out PB2 port. No other port is listed in the DS for RTC_OUT. See table 8, page 62. RTC_OUT also listed in table 10, page 90, and note for PC13, page 92.STM32H745 reference manual says:RTC_OUT can be direc...
While I am trying to write data in flash in memory it isn't being updated in the particular memory location while checking in debug session. And memory locations are showing 00000000 by default instead of FFFFFFFF and the image for same is attached h...
basically, qspi is know to operate in memory mapped mode. where,fmc_nor flash used to operate in what? is the nand flash is only operates on non memoey mapped mode, where memory needs some driver to access . please, clear this doubt best regards, jr_...
