Hi, ive been trying to understand how to program arm processors and I come from Arduino, but I never understood where the instructions that a machine understands come from, where are they all listen?

ARM processor instruction set
Hi, i would like to understand how to program arm processors in general but i need an in depth explanation or tutorial to show m ehow to find the commands or letter combinations( words) that make the MCU do something. if i were to compare written cod...
Resolved! DMA issues with dual-core STM32H745
I'm currently using the dual-core STM32H745, and am trying to utilize DMA's on both cores to R/W to/from shared memory. DMA's are only successful on the M4 cores, and always yield a DMA Transfer Error. I haven't done anything to modify the initializa...
Continuous watchdog reset on STM32F7
The STM32F767ZI on some of my boards has a strange behavior where is goes into continuous watchdog reset.- Could it be because of ESD? Or is there a known issue with the silicon?- What could cause the watchdog trigger?
UART communication problem
hi i'm trying to use the stm32H750 uart with Interrupt i managed to get it working but the message is a bit off ( alot ) here is a bit of the code uint8_t tx_buff[]=" "; uint8_t rx...
Hi, I am trying to sett up an STM32f030 processor and tries to get the ADC_ExternalTrigConv_T1_CC4 to trig the ADC from TIM1.
I am using the old StdLibs to do this since I am (I thought I was) comfortable with these. Anyone that can point out some code showing how to do this in detail? Have been struggling with this for three days and begin to loose my faith in this.Thanks,...
Resolved! Triggering ADC1 injected channel with TIM2 (LL library, STMG474RE)
ADC1 running with "Continuous Conversion" mode, no DMA. It has one regular channel 3 and one injected channel Temperature Sensor. I want to use TIM2 TRGO to active the injected channel every few second. However, its not working. When I set the ADC in...

SDIO(FatFS) File open(write) problem
Posted on April 03, 2018 at 05:35Hi.At the first time, SDIO works well but 10~20 minutes later, when i try to open a file(FA_CREATE_NEW | FA_WRITE options), there is no answer for 30 seconds and then SDIO does not work anymore after being shown FR_D...
Resolved! Hello Guys, I am facing problem in STM32H7 DMA. I had written code to receive the data from UART in DMA mode. In that i am transmitting the data in Polling mode and receiving in DMA mode.
In this at first time only data is receiving after that code is not executing RxCmplt call back function.Hardware: For testing I had shorted the both TX and RX pins together of STM32H743I EVAL board.UART Config : Baud rate = 9600,DataSize = 8bit,Mod...
