Hello,I am thinking to use an STM32H7 to write external data incoming from 16 GPIOs to an SD using the internal SD 4.1 Host controller. The data clock rate is 12 MHz.The STM32H742xI/G STM32H743xI/G DS (https://www.st.com/resource/en/datasheet/stm32h7...
Hello,I have a system using STM32F100RBT needs wake up from standby mode every second.Some operations it conducts when it wakes might take longer than a second.Each time before going to sleep, I read the current RTC time, and set an alarm for this ti...
HiAs a title, after I call HAL_SDADC_CalibrationStartand HAL_SDADC_PollForCalibEventfollow Refference Manual page 240, calibration progress will store an offset error value in OFFSETx[11:0] fields. So do I need to read this value and put in the calc...
Using ADC with DMA to read a bunch of analog inputs on a STM32F030RC, I am getting an error callback due to an overrun error if I select 1.5 cycles for the sampling time.Any slower sampling time seems to work OK.I'm confused about how this error coul...
Hi, Just purchased a STM32072B-EVAL board and loaded an example project on it. I cleared it from memory using ST visual programmer and now the LCD display is blank (i use to see the GUI). Did i accidentally erase the GUI? If so can I download it back...
Hello! I´m new with stm mcu´s and I would like to know how to generate a 10ns pulse with stm32f407 discovery kit. Is it possible?
Hello,I use STM32F100RBT. I want to enter STANDBY mode and exit every second.It works well, except for one issue: it always wakes up 1 second later.I run the following code, where I get the current time, print it and set an alarm for the next second ...
Hi, I want to deactivate all interrupts during a short period. I'm using __disable_irq();however, it says, that this can only be used in privilege mode. If I use this function my board crashes. I want to look up the privilege level, but the RM at pag...
Posted on March 03, 2017 at 12:34Hi guys!I'm configuring the Nucleo 64 with the STM32F446RE to use SPI as a Master.The problem I'm having right now is that the NSS pin is always low. Clock and MOSI are perfect. What I would like is that the NSS is h...
