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...
i use STM32F107+LWIP(2.0.3)+freeRTOSI wrote the program with the help of the following document :https://www.st.com/resource/en/user_manual/um1713-developing-applications-on-stm32cube-with-lwip-tcpip-stack-stmicroelectronics.pdfAfter connecting the c...
Hello STM community,I'm working on a project where I need to inject pre-configured config.ini and cacert.pem files into my STM32 target for mbedlts communication. I've gone through the STM32CubeU5 example for FileX, which demonstrates creating a file...
I am using the STM32H753 ARM Cortex M7 processor(Package LQFP208).My SYSCLK runs at the max. speed of 480 MHz and I want to configure my I2C1 (polling) in the Fast Mode (400KHz). I have configured the GPIOs and the modes but I am stuck at the "I2C_TI...
My OTG_HS2 kernel clock is PLL3Q at 48 MHz. If I use CSleep (only CSleep, not any of the deep sleep modes), SOFs are generated at the wrong interval (checked with protocol analyzer and oscilloscope). If I remove the WFI, SOFs are generated at the pro...
