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...
Usecase:Using the SDMMC module with DMA in HS mode (clock bypass @48MHz following CMD6 switch CMD), the SDMMC_IT_DTIMEOUT interrupt is raised when waiting few dozen of seconds after last successful data transfer (FATFS f_read in this case).The HAL_SD...
hi STM,i have STM32F303E-eval board which can me mapped to STM32F302VB mcu i/o lines.how to validate STM32F302VB source code using STM32F303E-eval board.please give inputs.regards,roushan kumar
Dear All,I faced a problem and I would like to issue a note for other developers. If it is a hardware bug in microcontroller, it may also be helpful for ST developers to fix it for a later revision. Let me explain what I faced in detail. (While tryin...
