STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I have a board that used STM32F07. I connect BOOT0 pin to GND via RES 10kOhm and left NRST pin open. At first i able to connect to STM32 and upload code but problem is after first time upload code (I use debug mode). It show STM is disconnect and aft...
I have STM32L011 board that i make. I left NRST and BOOT0 open. And i try to upload code using ST Link V2. But seem like the ST link is not recognize the STM it always show "Target no device found". Can anyone help me identify the problem? Please..Th...
Hello everybody,Im am currently trying to connect a STM32H753 to a AD7606B using the parallel interface (FMC) and got it working at some point where the CPU can read/write the data from/to the FMC but it needs a __DSB() before starting to use the rea...
I am working on the firmware for my STM32U575 based controller board. I cannot find in the documentation an explanation about the Low/Medium/High settings on a GPIO port. I see the bits to be set, and in MX the option for choosing the setting, but I ...
....so says STM32F334x4/x6/x8 Errata sheet STM32F334x4/x6/x8 Rev Z device limitationsDoc is dated 2021. No answers seen on web.Has this been fixed yet?If not, will it be fixed? And if so, when?Ta lotsRex
I've noticed some strange behavior when doing sector erase on this device.I erase sector 0..63 on bank 2 and write my data. I can confirm that this operation is correct by reading the flash starting on 0x08080000 using stm32cubeprogrammer.As a verifi...

I am using an STM32H7 to interface with a TI INA700 power monitor. I am using polled/blocking I2C, in particular HAL_I2C_Master_Transmit to set the register I am interested in reading, followed by HAL_I2C_Master_Receive. This has been working fine f...
I have built a board that is powered using a LiC and to conserve some power i run it under 1MHz (524KHz).I need 2 UARTs and one ADC for my application. However, since there's only 1 LPUART i use second UART to connect a cheap BLE module that i can se...
Hello, I am using an STM32F103CBT as an I2C slave. A memory buffer is to be transferred via the interface. Although hi2c1.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE; is set, I cannot measure clock stretching and the first byte transferred is always 0...
