hello i'm trying to make a project whit stm32f401ve and Digital Thermometer DS1621 using I2C protocol, and I have a problem whit i2c receive. here is my source code and photos of datasheet and simulation any help will be appreciated
static const uint16_t TEMP_ADRESS = 0x48<<1; int main(void) { HAL_StatusTypeDef RETURN ; uint8_t buffer[1]; uint8_t buffer2[2]; uint16_t Val ; float temp_c ; HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_I2C1_Init(); buffer[0]=0x...
NUCLEO-F411RE Openocd "Cannot identify target as a STM32 family."
Hi everyone,I am currently trying to learn rust embedded thanks to 3 stm32 based developpement board :Nucleo with STM32F103RBSTM32F3DISCOVERYNucleo with STM32F411REI have no issue with the first two ones but I can not make work the F411RE with gdb & ...
Resolved! QSPI nCS behavior on STM32H747
Hello,I am facing an issue with nCS pin of QSPI on STM32H747BIT.Reference manual indicates that SCLK is supposed to wait one period after nCS fall before starting operations :But I do not observe this wait on my board.*Yellow is the clock *Blue is th...
Resolved! Hello all, I have a question because this is not clear according to datasheet. I am using STM32H755XIH3 MCU and I wand to know if I want to use VOS0 MODE. can I use the SMPS on and supply only the LDO and work at VOS0 mode? thanks all.
at the datasheet:LDO only - can work with VOS0SMPS directly cant work with VOS0.SMPS on and supplies only the LDO - ?

Hello all....Ok....not sure what i am missing here but this fails miserably....The compiler hates when I try and assign test = The return function works fine, I have made the return variable static so as not to lose the scope....test is an array so I...
Bringing clock system configuration from NUCLEO-F207 board to stm32F207 based board
I'm trying to run an application that works fine on the nucleo board environment on a custom board using the same mcu. It's my first time and I'm using a protype pcb version with a very single circuitry. I was working over a firmware example with HAL...
