STM32L053R8Nucleo board waking from STOP MODE on UART and GPIO

Hi,I am trying to wake up the MCU from STOP mode. I am able to do so for either the UART or the GPIO interrupt but not both. It seems I have to disable the UART to get the GPIO to work but then of course I cannot get the UART wake code to work.Is the...

When will STM32F405RGT6 be back in stock?

STM32L4: ADC3 stops when dual ADC mode selected.

Hi,I am using STM32L476VGT3. When ADC1, ADC2 and ADC3 are configured independently, everything works fine. As soon as I write into the DUAL[4:0] bits of register ADC_CCR (common control register) to set ADC1 and ADC2 in dual mode, ADC3 stops. The dua...

Can DAC conversion of two separate channels be synchronised on the STM32G474 series?

I'm working on a project to generate composite video from an STM32 using the high speed DACs.This requires 3 DAC channels for red, green, blue fed by DMA.Of course the red/green DMA conflicts with the blue, hence the blue output is delayed about 30ns...

When is going malloc() / dynamic allocation to be fixed?

Edit: It seems there's a bug that will randomly delete sysmem.c and syscalls.c.If it happens, cubeMX won't regenerate them.Also no warnings at compile time, so you won't suspect anything was deleted.So the solution is to make a new empty project and...

Difference Between Regural mode and Injected Mode in ADC of STM32F469i-Discovery

In the STM32F103, what is the function of CK_INT in the Figure 123 of RM0008?

Data in the RAM of STM32

I use IAR to program STM32，the map file shows that ：the RAM is divided to​ 1.data Section；2.CSTACK and HEAP section；3.bss section；4.Unassigned part of the RAM。What I want to know is ​that:The Unassigned part of the RAM is used to do what? Because I w...
