I got this assembly code (see below) in an ST example code on secure boot and and I don't understand some lines :why do we have to push R1 five times in a row?why is LR set to 0xFFFFFFF9? That is causing a hard fault at runDoes anyone have better un...
Hi, I would like to, trigger an update event interrupt using software. My timer runs in One Pulse mode, the idea is, that another event should also run the code in my Timer ISR. So after this other event happens in my code, I don't want to wait for t...
Hi,I'm facing problem in reading data from EEPROM, which was written before power cycle.EE_Init() always causes formatting of EEPROM irrespective of EE_CONDITIONAL_ERASE or EE_FORCED_ERASE parameter passed, resulting in erasing the previous dataConfi...
I have implemented a basic I2C between STM32H7 (Main) and STM32F4 (Secondary) processor. I am using an array of size 6 to transmit from the Main CPU to Secondary CPU using I2C in IT mode.The HAL API for I2C requires the data_buffers to be of size uin...
This is probably a *** question, but I was wondering if there is a difference in performance between the following C statements given b is a standard boolean:bool b = false; //... if (b == false) //... if (!b) //...Will gcc in STM32 Cube IDE translat...
Hi all,I am currently working on GSM 4G module with STM32F429ZI. We are trying to connect to our server using LwIP and PPPos. I am able to connect to PPP and get PPPERR_NONE and IP address. I am also able to connect to our server using socket connect...
Hello,I am working with timers in a stm32 project. In the generic INIT function that is generated using the .ioc file important functions like HAL_PWM_Init(), HAL_TIMEx_MasterConfigSynchronization() etc are understandably called outside the user cod...
I am working with STM32G474RET6U MCU and I would like to check the values of bit filed EXTSEL (ADCx->CFGR.EXTSEL) the problem is that according to SFR view this bit field starts on 6th bit of CFR register, but according to the reference manual it sho...
Hello.I'm using the STM32U5A9J-DK development board to work on a project to display UART data on the screen textArea, and I've made sure that there are no problems with the communication between the PC and the STM32 UART, and with the process of Mode...
