Can the ADC on STM32F745 wake up the micro from Standby?
Would like the ADC on STM32F745 to wake up the micro from Standby if a certain positive or negative threshold is reached. Is this possible?
Flash ESP32 from STM32H7
Has anyone had luck with the esp-serial-flash library using an STM32 as a host?I tried to integrate this project into a Cube Project and was receiving ESP_LOADER_ERROR_TIMEOUT upon trying to connect_to_target(). I am basing this off of the STM32 exam...
DAC restricted to 0.5volt on a stm32L432 when you add a gpio_output to any PB
DAC restricted to 0.5volt on a stm32L432 when you add a gpio_output to any PB and appears to be the line __HAL_RCC_GPIOB_CLK_ENABLE(); added to MX_GPIO_Initwith static void MX_GPIO_Init(void){ GPIO_InitTypeDef GPIO_InitStruct = {0}; /* GPIO Ports Clo...
Resolved! STM32F20X ADC has voltage output
Hi all, I am now working with STM32F205 ADC1 w/ code generated by STM32CubeMX. I find that ADC pin has a 0.5V output even it is unconnected (floating). I tried pin PC0 (channel 10) and PC1 (channel 11) one by one and both have the same problem. Afte...
RTC calibration by Temperature using smooth calibration
I dont know how to calibrate rtc by temperature, i confused. When I look at RTC smooth calibration method like this, I thouht that i understand. After that i encountered AN2604 application note and i confused again.I cannot understand 2nd section in ...
how can i program the internal accelorometer to get the distance
Am using STM32F407VG -TX/DISC1
DMA circular | Changing data in mem-to-peripheral mode
I was wondering.What will happen when changing/writing data of the memory you assigned as buffer for DMA in circular mode. Will it be ok, garbage? Is there maybe a shadow register?Is this for every mem-to-peripheral interface the same?I'm very curiou...
Resolved! I need help with trying to figure out how to set my time using a push button and the RTC peripheral on the STM32G031K8 board. I can't seem to figure out how to get it to increment instead it just keeps getting reset to 00:00:00.
What do I need to do to be able to be able to set the time through the use of a push button. Is there a way to set the hours and min separately or does the RTC need to be set all at once? Here is my call back function where I am trying to set just th...
