Assistance with Debugger Issue

Hi all, I've been battling a frustrating issue on my STM32F407 Discovery board for the past few days. I don't know where the fault lies exactly but hopefully if I explain someone can point it out. I'm working on a robotics project, not doing anything...

1GB memory usage instead of 512MB for STM32L4R9AI

The STM32L4R9AI documentation says that it supports Macronix MX25LM51245GXDI00 and Micron MT35XL512ABA1G12-0SIT Octo-SPI Flash memories. These modules are not currently available for sale.Please tell me, is it possible to use MX66LM1G45GXDI00 instead...

How can I measure 4mA with a ADC from STM32? How to achieve 4mA -> 0 ADC?

Hi!I know how to measure 4-20mA sensor with STM32 by using a 160-165 Ohm resistor as a shunt resistor between ground and analog input of the STM32, and then apply 4-20mA into the analog input.But at 4mA, I gout about 0.6V into the ADC and then I losi...

QSPI issue

I am using STM32F746 controller and MX25L128 flash on a custom board.I want to make external flash loader file for my custom board.I followed the MOOC - External QSPI loader how toI got error while memcmp for (var = 0; var < SECTORS_COUNT; var++) { ...

STM32F1xxx shortages

We moved to STM after being let down by Freescale and TI in terms of sourcing. We are now finding massive MCU shortages and lead times > 30 weeks. Even despite this, we just found out that apparently STM is not taking additional orders.It is frustr...

WAKEUP from STANDBY mode and EXTI/NVIC IRQs

Hi all,I'm learning about low power modes , and I'm testing the RTC wakeup timer function.Datasheet talks about to set the IRQs for WakeUp timer on EXTI(IRQ 19) and NVIC(IRQ 3), but I tested in my code, with and without set these IRQs and the wakeup ...

I already have the board.
