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...
The crypto chip ATSHA204A needs a >60us low pulse on the I2C SDA line to wakeup. After that pulse the SDA should be high for at least 2.5ms. How must the I2C be configured to create the described pulse? The attached pictures shows a transfer with ad...
Hi, i want to display temperature value of LM35 temperature sensor on oled using stm32f103. i selected adc channel . even i am able to read adc reading but it is not varying properly and even i am not able to read exact temperature reading. can anyo...
Starting from Windows 10, the STSW-STM32102 driver is no more adequate and the usage of the native inbox driver is recommended.
Hi folks, I,m using STM32l4 MCU, I have configured USART3 with DMA1 with 1Mb/s baudrate. My concern is its worked fine if I don't put MCU in a Stop2 mode state. But if I put MCU in Stop2 mode state after waking up its not working. Here is the uart In...
I am using STM32G071RB. It is fine to connect only swdio, swclk, and gnd for program download. Is it necessary to connect the reset line?
I am using STM32L073.When using this ADC, the EOC of the flag ADC_ISR for which AD conversion has been completed does not change unless the EOCIE of ADC_IER is set.is it right.
I have the STM32L475 working in STOP2 wake up as WFE based on the RTC. I would now like to add in an external interrupt source (WFI). There doesn't appear to be a way to use both a WFI and a WFE as wake up. The only way I could see would be to have a...
Hi All,When I try to boot the M7 core alone and I disabled the M4 core. I create a simple stm32Cube project, the code stuck at:while(!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY)) {}inside the SystemClock_Config() function. The VOSRDY will set only when I cha...
I have migrated code working fine on STM32F767 to STM32H7A3.The strange thing is DMA2D_IRQHandler does not get called upon memory-to-memory transfer complete. I call HAL_DMA2D_Start_IT() function, it returns no error, it does what it should, I can ev...
can it be that it is only possible to program it only with the STLINK-V3MINI and not with the eval board usb?my STLINK-V3MINI doesn't work so i rely only on the eval board usbif the is a guide for the STEVAL-STWINWFV1 for the wifi connectivity it wo...
