Doubts about using QSPI for STM32L431？
Now the project uses STM32L431RC external nor flash to save the data. I want to replace STM32L431RB external QSPI flash, which can reduce the cost, but the program byte is too large, so it needs to be put into the QSPI device to run. QSPI flash is di...
STM32L100 TIMx_IC2
Hi there!I have this MCU and i see as an alternate function 14 it can configure PA1 as TIMx_IC2.I cannot find in the documentation or block diagrams the meaning of this function? is it like a TIM_Channel? or like TIMx_ETR?Thanks!
STM32F103 BUS MATRIX
Hi everyone! new around here.. i am taking an online course about DMA controller.At the very first lesson they teach how to check routing using DMA BUS MATRIX.The problem is that i cannot find of any of my two board that uses STM32L100 or STM32F103.A...
Reset doesn't seem to put the IVT MSP value into the MSP
I'm using the STM32L152 processor. I just noticed that on a reset the value at IVT slot 0, which should be the MSP value, doesn't get put into the MSP. I see another value there on a reset. I added "ldr sp, =_estack" at the start of Reset_Handler, an...
ADC_RegularConversion_DMA project question.
Hi Everyone. I'm modifying a the example project "ADC_RegularConversion_DMA" for the STM32F4-Discovery board.I now want it to work via TIM2 trigger. I would like TIM2 to trigger the ADC, and then the DMA to transfer the ADC result to a buffer.The pro...
Resolved! Saving some data in RAM between Reboots.
Hello,I am trying to add s RAM section at the end of the RAM to savesome data (states) between warm reboots, when the watchdog kicks due somewiring problems (i2c).I changed the ld file as:I reduced the stack -2kI reduced ram -2kI created a RAMAUX and...

All the STM32L4 reference manuals. describe LPTIM_CFGRBit 20 WAVE: Waveform shape The WAVE bit controls the output shape 0: Deactivate Set-once mode, PWM / One Pulse waveform (depending on OPMODE bit)OPMODE bit is mentioned nowhere else ....
Community emails
I want emails for replies to my posts, but I'm getting a few emails per day on random topics that I am not involved in. For example, I just this: "FLosa.1 asked group STM32 MCUs: How do I send my input data to a neural network on an STM32F4 to make ...
STM32H753BIT6 - RTC battery discharge current
We are using STM32H753 controller In Power off condition we checked VBAT discharge current in STM32H753BIT6 .The discharge current is pulsating from 4uA to 28uA.We enabled only RTC peripheral.We are not sure why the behaviour is like this
