Posted on June 13, 2016 at 17:40Part of ARM's specification of the core (as given by ARM® v7-M Architecture Reference Manual, or ARMv7M ARM for short :) ) is the SysTick counter, and part of that counter is a read-only register, containing a calibr...
Posted on June 02, 2017 at 11:37Hello everyone,I have recently switched from 8 bit to 32 bit mcu. I'm Working on STM32F429xx series. As per datasheet of STM32F429ZI mcu (cortex m4), each of DMA controller have 8 streams. is it possible for DMA contr...
Posted on May 31, 2017 at 17:02Hello,I'm still trying to continue the programmation of my STM32F405 board and I have (again) a little problem. I use a OP-AMP to compare 2 signals by sending him a integer. The return value is always the same even if ...
