HI. I'm trying to understand what is Stack aligment and what is it for. Cortex-M3 has a special bit STKALIGN in SCB->CCR register. Theoretically this bit is set to 1 in new revision of core, but when i look through debugger this bit is clear.I've rea...

Greetings embed ProfessionalsRecently taken onto STM32 and getting along quite well so far! Regretting for not having done so earlier so plenty of catch up and "learning to do" (ps. mechanical engineering background here). Learning in particular; I'd...
Hello guys.I've been trying to learn how to program STM32 MCU's using registers.This time, I've attempted to configure a basic UART programm in which I would like to send whatever I receive via UART back to the source. Basically an echo program.I'm i...
Hi,I have a NUCLEO L552 and I would like to run a very simple program (just blinking a led).I have placed my vector table @ 0x08040000 as described by the data sheet. to program the flash I use the J-Link from Segger. What is strange, is that I canno...
Hello,I'd like to use my STM32F446 in the following way:ADC 1&2 are connected to an analog sensorOnce the sensor connected to ADC 1 passes a certain voltage, start using DMA to transfer ADC 1&2 values to buffers.Once the transfer is complete, stop th...
Hi everybody ,does anyone have source code for writing data in SD card?I am using STM32F103C8Txthanks alot
HAL_RCC_GetSysClockFreq(void) in stm32f7xx_hal_rcc.c uses a (unt64_t) divide which could be avoided. This uses, on my build, 716 bytes of code space alone for the required _udivmoddi4 call, and this is not used anywhere else in my code.Would it be po...
I'm trying to send exactly 8 bits of data, and check my results with tera terminal, however I'm not seeing anything come up. I noticed that on the block diagram for the STM32L476RG nucleo board, that the APB1 Bus is also connected to AHB1, but there ...
Hell guys, i'm trying to communicate with LCD2004a with the I2C extender.i followed this guide https://www.youtube.com/watch?v=7mQppaEJjT4what i did:I generated project using CUBEMX to Keil uvisionconfigure I2C with those parameters: 100Khz CLK, slav...
