Can I combine SRAM1 and SRAM2?
Hi,I use STM32L476QE.I want to use the entire RAM (96KB SRAM1 and 32KB SRAM2) as one continuous memory, is that possible?I use IAR

Why is the Option Bytes of STM32G474xx chip isn't one-to-one corresponding to its register?
Category 3:In Option Bytes: (0x1FFF7800)Bit 22 DBANK:0: Single bank mode with 128 bits data read width1: Dual bank mode with 64 bits dataThis bit can be written only when PCROP1/2 is disabled.Bit 21 Reserved, must be kept at reset value.Bit 20 BFB2: ...
STM32F4 Discovery MCO1 from HSI clock source looks like an analog signal when I expected it to be digital.
I used CubeMX to point HSI(16 MHz) to Master Clock Output 1(no prescaler). I hooked it up to my o-scope and saw the signal in the following picture. It's obviously not a digital signal, but shouldn't it be? What's going on here?
How to determine the DMA transfer rate?
I am using an STM32F4466 Nucleo board. I am using DMA 2 for ADC1 to memory transfer.My AHB frequecy is 180MHz. I want to know how long does it take to transfer a half word.

Is it good idea to define RTC SRAM section in linker script?
I think it would be the easyest way to work with RTC's SRAM. In this case I just need to define the section in code where to put my variables. I would like to see someone's opinion who is more experience with STM's than me.
Basic timer interrupt example?
Beginner requesting an example of a timer interrupt every 20 us. Am using a Nucleo-F767ZI. Not sure if CubeMX is used for this as the interrupt is timer not external?
Why can't i send a specific number with i2c?
I have started writing an i2c driver for the stm32f051c8 and have stumbled upon an issue.The code i use to test a very basic version is: RCC->AHBENR|= 1<<18; // gpio clock enable gpiob RCC->APB1ENR|= 1<<21; // enable i2c1 clock GPIOB->MODER|= 2<<1...
bxCaN 16-bit rx-filter
In the manuals it usually says that the 16-bit filter includes 11-bit STID, IDE, RTR and EXID[17:15]. Does that mean that if standard CAN IDs are used, EXID[17:15] covers the r0-bit and two highest bits of the 4-bit DLC-field? I haven't found that me...
STM32F429 CAN bus example code to transmit and receive message using can bus analyzer
Hi hello,As iam new to stm32 i don't know how to use CAN bus to transmit and receive through CAN bus analyzer to stm32f4 controller, could some one help to give some sample or example code to send and receive message using CAN bus analyzer to stm32f4...
