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,

how to enable and use CUSTOM_HID_GetReport_FS?

I am using Nucleo STM32 F767ZI board. I want to send data via interrupt endpoint. In LPC2148 is done using HID_GetReport function. how to do the same in STM32 MCU?

STM32G0B1 Device lock?

Hi, I am currently trying to develop a DFU using the chip's dual bank feature.After bricking my second prototype (only recoverable by exchanging the G0) I am out of ideas what could be the problem.I could at least track it down to manipulation of the...

Is STM32F303RB PORTx bit banding possible?

I'm using STM32F303RB seriesIs there PORTC with bit banding?Best regrads. 

Wordlength setting when using Modbus RTU as UART

Hello, Now I'm using Modbus RTU and UART. Modbus RTU communication is being performed through UART. Modbus RTU setting is data 8 bytes, but communication is possible only when uart wordlength is set to 9 in STMcubeIDE. Why is wordlength 9 when data i...

Pulse edge detection level of STM32 Timer input capture

I'm using STM32F407 and I want to capture a pulse of following detail:Frequency: 100~1000 HzLOW voltage: 0.7vHIGH voltage: 1.5vand I'm wondering that whether STM32 input capture can be triggered on such 0.7~0.8V height pulse, or not.If not, what is t...
