Hi, I have a design with STM32F407ZGT6, using lots of stuff - external SRAM, USB, SDIO, USARTs for MIDI in/out, etc. Also I use VBAT to maintain RTC and device settings while it is off.First, I had a problem with high VBAT current (about 1mA) while t...
Dear ST Hello,I am implementing an infinite state machine on stm32F409 board and I have an issue.I Have a periodic pwm of 60us triggered. I Want to move all the code to the main while loop from the Interrupt service routine.My objective is to run ea...
Hi, I would like to send a data from my STM32F401CC to Arduino. I have connected Tx to Rx and successfully upload the code to stm32 and Arduino Uno. I don't get the values right, only first four readings, then all the values become random. This is my...
Hello Gals/Guys. I recently purchased a NUCLEO-F439ZI after playing around with F0-DISCOVERY. As is tradition, I wanted to make a LED blink. I have failed miserably. I started in CubeMX to for the initial setup using all the defaults. Using the...
Hello I am working with the STM32f4 development board. I'll make one LIN(Local Interconnet Network) master and one LIN Slave instance but I don't have any example.Has anyone created a sample code?
Hello.Reffering to AN4207(Doc ID 023945 Rev 1) Single ended zero reference mode (Page 9):This mode injects an input common mode of half scale to the ADC thus maintaining the dynamic range the same as in differential mode (-32767 to +32767). In this m...
I use STM32F103CB in my project. but I found timer interrupt fastest time can't less than 1us. Timer prescaler is 0, up counter mode, counter period is 36, no inernal clock division and auto-reload enable. When timer interrupt occur. I set Pin high ...
Lead time for many parts get into the 52 weeks region. It would be helpfull, if McuFinder would give a lead-time estimator, e.g. green for good, yellow for > 4 weeks and red for > 26 weeks.
Hi all,I test the timer input capture mode. The input range is 1Hz ~ 100Hz.I set the parameter as below. (Using CUBEMX)Timer Clock : 60MhzPSC : 6000ARR: 10000void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) { HAL_GPIO_WritePin(LED_PORT, IN_...
