Hello.i need to make EEPROM emulator for data storage here i am using stm32l432kc controller. and i am using last 4 pages of internal flash memory to emulate EEPROM. start address of page 124 is 0x0803E000 end address of page 127 is 0x0803FFFF. each ...
Dear community,I'm currently working on a student project where we need to analyze the performance of the FMAC unit of the STM32G4. My idea is to implement an FIR filter and measure how many clock cycles the FMAC operation takes to filter a predefine...
Our design involves storing the images in external flash. Images are fetched in run time from external flash and displayed on LCD. Is there a built-in integrity check to verify the validity of the bitmap before displaying on the LCD?A question came u...
Hi,I am relatively new to STM32 development and would greatly appreciate any assistance with the following issue.I am encountering the following compile-time error: C:/mvt1/TouchGFX/gui/src/settingsa_screen/SettingsAView.cpp:7:10: fatal error: ..\Dri...
Hi ,I am working on to implement functionality to detect flash 2 bit ECC error. To test my implementation followed below method in STM32U5 reference manual. With this method, I am able to generate flash 2 bit ECC error.However I have following obser...
Hello, We are using STM32H573AII3Q in our application. It has in-built SMPS for core power supply. Just wanted to know can we disable this SMPS and use seperate external 1V LDO to power the core?
Hello,Can anyone suggest whether or not I need to connect external capacitors to the VREF+ pin if I plan to use VREF only for the onboard DAC?Could this be a hardware problem?STM32G431CBT6. The problem is that on the oscillogram I see oscillations wi...
Dear all,I have a custom pcb with a STM32H753 on it.There I'm already using the TIM12 function for generating a PWM output signal This is my init function - generated from CubeMX: void MX_TIM12_Init(void) { /* USER CODE BEGIN TIM12_Init 0 */ /...
I use STM32CubeIDE 1.16.0 to do project and use STM32H743.when my code is over 512K, I re-write ld file,but download is failed.But I use STM32CubeProgrammer to download the same elf file,it worked!!! So what's wrong about it ?
Hello,VCAP1 and VCAP2 are external capacitors for the core's voltage regulator.The data sheet for the STM32F479VI states that, "Stabilization for the main regulator is achieved by connecting an external capacitor CEXT to the VCAP1/VCAP2 pins."I inter...
