hello , I use spi and ı use slave mod spi. When I send a frequency of 500khz or more as a clock so data is shifting or I recieve wrong data but I send a frequency less than 500 khz I recieve true data. what is the reason of this.( use stm32h743z...
This is the how I'm trying to write to flashBasically I pass my uint16_t array to a function called FLASH_WriteA which accepts the array, the destination array or the location and the lengthvoid FLASH_WriteA(uint16_t * src, uint16_t * dest, uint16_t ...
In FLASH_OPTR, both DBANK and DB1M are r/w and have no restrictions beside that PCROPA/B needs to be disabled. For 1M device there are two(?) sensible settings DBANK=1, DB1M = 1 for 1Myte dual bank continous modeDBANK=0, DB1M = 0 for 1Myte single ban...
Beginning to explore timers in STM32F051 (from DiscoveryF0). I'm starting with TIM6 (basic timer) as I'm looking for nothing more than a periodic interrupt. Before I get started, I'm wrestling with where to find complete register reference for the co...
I need to calculate angle value with input of sin/cos from ADC1/ADC2 channel by DMA way. As using the cordic of atan2 function,I think that two parameters of Y and X need to be written to pInBuff as like the key code below, is it correct? sCordicConf...
I want to wake-up from standby mode on a STM32L422xx using PA2 (WKUP4) with pull-down enabled in PWR_PDCRA. Wake-up signal can go up to 5.25V at this pin.Can this configuration cause any problems e.g. high current injection during wake-up phase?Thank...
