I have an STM32F401 MCU acting as a master on its I2C1 port linked to a slave STM32F407 MCU, and a couple of DIO expanders (PCF8575). After a random period of between minutes and days the Master appears to stop updating the Slave MCU but continues to...
I already have the board
Hi team,I working on stm MCU using IAR ARM Workbench ver8.40.1 and previously I was getting a Fatal error "intrinsic. h", anyhow I solved it by giving as "intrinsics. h" and later I got this error. thanx in advance.
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...
