I want to read the Vdd (link to VDDA) of my board with the ADC in a STM32L072. I try read it through a divider bridge or through VrefInt, and both give me a value far below the voltmeter value.here is my config: hadc.Instance = ADC1; hadc.Init.Ov...
Hello, I'm using stm32F446RE.Sending CAN messages to two controllers and it stopped working after some seconds if time delay between the messages is less than one second, And it's slow for my project.looking for suggestions, attaching some of my code...
Hello All....Simple question. I am using the functions(HAL_TIM_Base_Stop_IT and HAL_TIM_Base_Start_IT). Basically I set a timer to count to a value and an interrupt occurs. The timer starts on a GPIO edge. I would like the timer to always zero out at...
I'm reading TS and clearing TSF, ITSF, TSOVF flags upon power up. But when power cycle happens again, the TS registers are still containing the previous value, but not present value.
Hello ST community!I would like to know if someone can help me with my project, I need to read the analog measurements that enter the MCP3208 ADC through SPI with STM32F103C8T6. I need to read all 7 channels of the MCP3208. I've been reading the data...
Apnote "Achieving 32-bit timer resolution with software expansion" (AN2592) mentions that it is possibleto create 32bit input capture with only one 16bit timer. Combine interrupt from update event to count timer overflows and regular 16bit input cap...
I have two STM32 based development boards and would like to get CAN example (slightly modified) to work with a simple data packet of 2 bytes sent from one board to the other. But I detect no valid CAN frame on the bus.The setup is taken from here: ST...
