STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi,I'd like to run synchronous PWMs on TIM1 and TIM8 of an STM32F446RE. I use TIM2 to trigger both timers.My setup:Master: TIM2MSM bit is setTRGO = Enable bit (CNT_EN)Slaves: TIM1 and TIM8Slave mode = Reset modeTrigger source = ITR1I appended my Cube...
HiFor a project I am using a STM32F429ZITx and need to implement OTA functionality. With single bank chips I have previously put the update into the free part of the flash, then copied it over and restarted.With 2 banks I came as far as erasing the u...
The reference manual (link below) gives some details regarding setting the high and low voltage thresholds for the ADC's analog watchdog in the ADC_HTR and ADC_LTR registers. However, I can't find any details explaining how the values put into bits [...
Short story: the board was working fine, but now I cannot communicate with it from the IAR IDE (cannot debug/download)Long story:I am using the IAR Embedded Workbench IDE - ARM 8.50.6 to program/debug my NUCLEO-H745ZI-Q board. I had successfully uplo...
Hi everyoneI'm currently working with the STM32H755ZI SPI1 peripheral. I'm using low level driver to read 2 bytes of data. I'm transmitting 2 dummy data bytes (0xFF) in order to get some response from the SPI slaves. Most of the time, the receive wor...
The problem is crc used in iap for transferring the bin file is to only check for errors during the transfer process , however i dont want any random bin files to be flashed into the flash or executed from it, only certain signed bin files need...
Hi! I'm pretty new to STM microcontrollers and I found myself in a strange situation:I want to create a prototype for a project on Nucleo-L011K4 (and later use L081KZ for the PCB version) and I need to run ADC on multiple sensors paralel. But all tut...
Microcontroller low cost for home health care design
Hello,I have a global variable, wich is accessed by multiple ISRs. Can I safely disable and re-enable the interrupts within an ISR using __disable_irq() and __enable_irq()?Or is there a more elegant way of protecting the variable access?best regards,...
hey,i have an STM32L432KBU6 and i want to serial communicate with my chip. I connected the SWCLK, SWDIO and the SWO pin and followed a couple tutorial on youtube but i just cant get the Serial communication done. i just want to open serial monitor li...
