STM32L4A6ZG boundary scan has stuck inputs every 24 cells

Our design has a STM32L4A6ZG, we are using our own boundary scan tool to test the PCB. During testing we found that input of PF1 (cell 375) and PD13 (cell 207) where always high after some more investigation it looks like the inputs that are 24 cell...

Initialize SDRAM in SystemInit

Hello,I am using a STM32H7A3 and a SDRAM MT48LC8M16A2P.In a project using the emWin graphic library, I would want to store the relative buffer 'aMemory' in SDRAM.By reading on community and seeing the examples I understood that I have to write a Syst...

I have a case open in my profile due to technical issue with one disco board and the ST employees are updating me on the situation. I would like to reply to them but I keep getting an error whenever I try to post a comment.See screenshot for referenc...

I am planning to use temp sensor part TMP451HQDQWRQ1 with STM32F303ZET6. This sensor is SMBA based. Where to connect SCL & SDA from sensor to MCU? I can see below 4 pins in MCU, I2C2_SMBA I2C3_SMBA I2C1_SMBA I2C2_SMBA Please help.

Trying to use PWM to toggle LED, won't output to LED

Hi folks​New to STM32 and getting into it by starting with clocks, timers and ADC. All I want to do is dim a few of the onboard LED's with a pot on a breadboard. Stepping through debug I've found the following Analog input is reading values from the ...

Hello, I used nucleo F303k8. I use timer1 to create PWM. When I startup the nucleo I saw 2 pulses that I dont understand why,?

How to access the DHCSR, DEMCR registers on the stm32l011f4p6 processor?

According to the RM0451 Reference manual (Ultra-low-power STM32L 0x0 advanced Arm ® -based32-bit MCUs),I use the SWD protocol to access debugging:1. Turn on the power and set the reset2. I initialize SWD3. I get access to1) SW-DP has an internal ID c...

In STM32L562VET6Q Microcontroller in that my question is how to configure/map SRAM 2 memory address as 0x2003 0000, so , i can use it as contiguous memory of both SRAM 1 and SRAM 2 i need big size continuous memory block.

"64 Kbytes located at address 0x0A03 0000 with hardware parity check (SRAM2). This memory is also mapped at address 0x2003 0000 offering a contiguous address space with the SRAM1"
