Hello, I am using the STM32f107vct6 which has 256kbyte flash memory size. However, after connecting to MCU via st-link V2 and ST-link utility it shows me just a few pages of my flash memory size and the wrong flash memory size.what is my mistake?
Hello, I have implemented a high-speed USART @921600 baud rate with STM32f10x @72Mhz. I want to send 3000 Bytes to a slave MCU.In slave MCU, I used USART DMA to read MSG[300]byte data collect the data, and copy them into a larger array(Data[3000]).My...
Hi all,I'm working with STM32F4 disc board, I'm using PB8 and PB9 as interrupt input, those pin shared same irq handler EXTI9_5_IRQHandler I would like to know if it is possible to only deactivate the interrupt on PB8 before STOP mode but leave the...
I have an MT25QL01GBBB8ESF-0SIT controlled by an STM32F765VGT6 microcontroller. This was coded using C and the STM32 HAL in the STM32CubeIDE. It was verified working using different SPI commands such as read JEDEC ID, page program, etc. However, afte...
I recently started working on a custom board project based on an STM32G070CBT and using the SWD interface through an ST-Link Debugger. The previous developer is no longer working, and all he left behind was the Keil uVision project. So, everything sh...
Hi, We are using STM32G070RB for our application. Need a reference design for the schematic & also as mentioned in below screenshot there is requirement of L1 inductor on AVDD pin, Please let me know the Required value of inductance/impedance or plea...
Hello, Im using STM32H745 on custom board, with Micron Flash Memory (MT25QU512ABB)Board is tested, I was able to manage NOR memory through QSPI.I tried to change nonvolatile configuration register to set two things:Number of address bytes during comm...
Hello, Am working on STM32L412RBT6. We made a custom PCB for our product and Am trying to PD2 as digital output as toggle function. I can't able to find any high output at PD2. The pin PD2 is always remains low. Please help me on this
Hi Guys, New in STM32 design. We are going to use STM32G4 MCU (specific P/N hasn't been selected yet).We want to use dual image boot (for upgrade option). I need to choose an external QSPI flash for that.What is the maximum image size for STM32G4? Th...
I am using the STM32 G431RBT6 chip and UART 3 for data transmission. The transmission works normally, but after about 20-30 minutes, it suddenly stops completely. Here is the function I am using to send data: bool SendByteUart3(uint8_t byte) { HA...
