Hi, I got a problem with the reception using USART7. I'm using it in the interrupt mode but the problem is that the data in the buffer is not coming well. I'm connecting STM32F407 board with the STM32F746 using UART. When the F7 transmits, there's no...
Hi,I'm using STM32U575I-EV and CubeMX.Please tell me about benefits using lpbam in CubeMX.I thought that if I properly set up the peripherals that support LPBAM on the "Pinout & Configuration" screen, I could do the same thing as LPBAM Scenario.When ...
Hello,We use STM32F765VGT6 in our product. The datasheet says 1MB of flash memory available but it looks like there is 2MB available for use 0x0800 0000 to 0x081F FFFF. Is this a documentation issue? Can we use the extra 1MB flash starting from 0x081...
Hi, I have problem to generate correct output waveforms with Altium SI tool using the IBIS model stm32f765_767_777_lqfp144.ibs. I'm trying to generate a clock output signal in PB3 configured as SPI1, no pulls, fast speed or high speed but the result...
I finally got my hands on a STLINK-V3SET. I'm eventually going to use it on a custom board we're spinning up but I thought I'd start with STM32CubeIDE and a Nucleo-H7A3ZI-Q. I've tried several configurations per the manuals and always get this erro...
I just was testing the bootloader, when it did not respond after writing the flash. Upon inspecting the memory, i found the last 2 bytes have not been written? (i guess the uC went to hard fault or something)It should not be this way?
Hello, I am having an issue with the STM32 GPIO. The problem is that immediately after supplying power to the chip, GPIOs such as PJ0, PJ1, PJ2, etc. are momentarily powered, behaving as if they were set as outputs.Below is the test sequence:1. I cr...
Hello Community,I am slightly confused while selecting the external high-precision Clock source for our application that uses STM32G474RxT3 series MCUs. I want to use DSC1001DL2-024.0000T as I have these in our inventory, I checked for the operating ...
stm32l071CB flash only 128kB, can fatfs run on Stm32L071CB? Roughly how much space it takes up?The FATFS I used to use on the stm32F103VE platform took up about 200KB of flash because of several large arrays。
HiI design a board based on the STM32H7xxI-EVAL, the ethernet PHY is LAN8742A-CZ-TR and according to its the datasheet the crystal specification the drive level need to be 300uW but the maximum drive of X53T-C20SSA-25.000MHz level is only 100uW.Did y...
