STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
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...
