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...

Cannot post comment in my case

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"

How to add delay before switching Tx/Rx mode in USART Async RS-485 mode (Hardware flow control).

I am using USART 1 and USART 2 of STM32L56VE series microcontroller in RS-485(Hardware flow control) in Async mode, I am using PA9(TX),PA10(RX),PA12(RTS),PD4(RTS),PD5(TX) and PD6(RX) pins. I have observed Transceiver is switched to send immediate at ...

I have a Nucleo L053R8 card. I want to run a different card using the top part of this (section CN4) but I cannot provide 3.3 voltage via vdd_target. So I tried to use the 3.3 pin in the JP1 section, but my code cannot be transferred to my other card,
