STM32G474: Descriptions on access paths to SRAM2 is inconsistent within a data sheet.

DS12589 Rev 1 (for G431) and DS12288 Rev 1 (for G474) both states in Section 3.5 that SRAM2 can be accessed by CM4 core through System Bus or through the I-Code/D-Code bus. However, Figure 2 "Multi-AHB bus matrix" suggests that SRAM is only accessibl...

How to swap two memory regions from different banks in FLASH Memory for STM32L475?

Hi,I am working on B-L475E-IOT01A2 which is a STM32L475 series Discovery IoT kit and has an ARM M4 cortex. It has two banks of FLASH Memory of size 512 KB each. I am implementing two applications along with a bootloader and all of them are stored in ...

i work on a project with stm32l010f4 how can i get a regulated stable voltage from one of its output pins?? how can i get VREF as an output for adc?? is there any code for this??

hi every one, i have a question about MDIOS pins in stm32f765zi chip, PA6 and PA10, in the case which we use these pins, Micro is master or slave? because "S" in the name refer to slave, thank u

Deadtime about PWM

i config TIM with PWM , and insert deadtime , i found the first deadtime is longer than later , this why behave so ?​

STM32L05 + SPI not work after stop mode

Hi,I am trying to use an e-paper and a STM32L053C8 microcontroller.When i use the display in the first cicle, all works fine, but after wake up from stop mode, the display not works. Maybe the SPI interface not start well or i am doing somthing wrong...

OCTOSPI with dma used for external DAC

Hallo.I want to use OSPI to feed an external DAC with data.Data shall be transfered through DMA from memory to OSPI. Eight bits and OSPI-CLK shall be used.In the first place I set up OSP in octo mode, disabled all IRQ etc. and tried to write one byte...

IF ANY NORMAL STM32F SERIES controller DOES NOT HAVE DEDICATED FSMC OR FMC PORT THEN HOW TO INTERFACE EXTERNAL SRAM AND FLASH WITH THAT CONTROLLER?

ADC accuracy (offset and gain big errors)

Hi, I'm using the STM32L451VC microcontroller. I'm trying to measure the analog input with an internal ADC (12 bits resolution). The value is compensated with the vrefint (1.21V) of the microcontroller, following the next formula: Vchannel = (3 V · (...
