Greetings! I'm experiencing strange behaviour when invalidating or enabling the DTCM-RAM on STM32H723 (using the Nucleo board for this). When debugging and using the step-over functionality, the invalidate and/or enabling process for the D cache seem...
i m using an stm 32 microcontroller to read adc channel, this is my approch: discontinuous DMA requests in Normal Mode and single conversion adc for multiple channels, i want the adc channels to be read 20 times in a row, with a frequency of 1Khz usi...
I made a board with spi1 connect a lora module, and the nss pin, I just want to use soft control. But I found that before I enable spi1, the SPI CR1 and CR2 register value as: (gdb) x/2wx 0x40013000 0x40013000: 0x00000024 0x00000040 but afte...
Scenario:Able to connect the STM32WB55 as Peripheral/Slave to Master (mobile phone). Communication is mostly solid between these devices, however, during periods of inactivity, the STM32WB55 randomly stops responding to the Master's empty PDU and re...
In the datasheet of W25N01GVZEIG,Data program load and quad data program load can transfer up to (2048+64) bytes.(The transfer of data between the controller and the external flash uses DMA)When I try to write 2048 bytes, nothing is written. The same...
I'm a beginner with STM32 and I'm trying to generate a sine waveform using a STM32G4 through the NUCLEO-G431KB board to be exact. I've been looking through tutorials on how to generate a waveform using a STM32G4 board, particularly this tutorial but ...
I use STM32CubeMX(ver 6.12.0) to configure STM32H7R3Z8T6, when i try to enable FMC to control nand flash, it suggest "NAND Flash 1 is not fully configured. Please enable addresses and data in the Mode section." as followingsomeone please help!!
Hi,I am new user of ST Microcontrollers. I am using STM32F4 Discovery board.Till now its default HSI oscillator I was using, now I am going to use the HSE clock of this.STM32F4 Discovery board have 8 MHz crystal, which is connected to the microcontro...
After normal power-on, the MCU does not run, but as long as something is used to shield it, it will return to normal. Help to see what is the reaso
Hallo,we are using STM32H735G-DK boards and wondering whether unaligned access of memory mapped HyperRAM should be generally possible or not.In the errate sheet for the STM32H735https://www.st.com/resource/en/errata_sheet/es0491-stm32h72xx73xx-device...
