Posted on January 02, 2018 at 22:54Is this a typo, or are there some other register bits which allow to select the source of the SAI1-B clock frequency?JW
Posted on December 30, 2017 at 13:21Hi, everyone!I am trying to implement PID controller from arm_math library. I use this code as kind of example for this https://stm32f4-discovery.net/2014/11/project-03-stm32f4xx-pid-controller/ I am getting erro...
Posted on September 27, 2017 at 22:10Clocks in the I2S diagrams in STM32F4xx DS show two settings of CPOL, although the difference appears to be minor:Also caption of several figures in I2S portion of the SPI/I2S chapter in RM0090 contain CPOL=0.How...
Posted on December 24, 2017 at 19:54The manuals mention 'ART accelerator allowing 0-wait state execution'.Do all STM32 models run off the internal flash at maximum speed? Would code copied to RAM run faster?-- pa#performance
Posted on January 02, 2018 at 21:01(this is re-post because of the 'forums issue')I have the following function to write a RTC backup register of 446ZCT:All RTC initialization code is generated by CubeMX.void put_backup_num(uint8_t num){ __HAL_RTC_...
Posted on December 02, 2017 at 09:38Hello guysI want check the STM32F207ZG can run with arduino. But the F207ZG is too big ,144 pins .We plan to use F207VG 100pins, it is can run complaint with arduino ?Is there anything to change ? #arduino-stm3...
