Hello,Am using STM32H745XI device same as the disco board and external flash on QSPI (MT25QL512A) single chip flash. IAR IDE is used for development. Though there are reference driver codes available for MT25QL512A but different controller is used. I...
Hi, I am using a stm32h743zi to stablish a connection with a ESP32 via SPI. I was using SPI4 at the beginning with one board that i made using these pins:66 PE13MISO67 PE14MOSI65 PE12SCK68 PE15INT64 PE11boot cs NSSUsing the pins above my program was ...
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 ...
I created a 10Hz sine function with phase of pi/4, amplitude of 1000, bias of 2000, a sampling rate of 1kHz, and 2048 samples (20 periods in total) and saved it into q15_t input[2048].I created a fft stract by arm_rfft_init_q15(&S, 2048, 0, 0)I enter...
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 ...
Hello everyone,Hope you are all doing well. I am currently working on a BMS that includes an STM32L562VET6Q MCU and other peripherals.ARINC429 is completely new to me. This week, I have been reading the ARINC 429 (HI-35850) datasheet and trying to co...
