STM32 MCUs Products

Could somebody please tell me what firmware version is provided on ST8500 (if I order only the SoC...not a dev board) and what are the resources for developing?

BOR vs PVD Detection Logic

We have seen PVD triggers when there is transient load of 1A added on the 3.3Vdc (loaded additional to our design through electronic load) and it triggers when the transient load dips the 3.3V for duration of ~450 micro seconds.We have seen BOR trigg...

Resolved! STM32F051 ADC Vref problem

Hi there!I need your help before i became crazy. I configurate (with DMA) 9 ADC input plus one for Vrefint channel of my STM32F051 discovery, Now my problem:i read a wrong value of Vrefint channel the value is equal a Ing1. But if i configure ony Vr...

Nucleo board with STM32H7A3 - ADC and OpAmp I know the maximum sample rate for direct , fast and slow channels. But what if I use an opamp in the follower mode and connect it internally to ADC. Is my sample rate the same as for slow channels?

Resolved! STM32L432 use both usart1 and usart2 receive missing data

Hi,I write the firmware using STM32L432 (NucleoL432-KC) used usart1 and usart2 with DMA RX/TX and received idle line.The usart1 and usart2 using pin of the same port (PORT-A)The problem is lost receive data if I receive data on both port at the same ...

Resolved! STM32L0 VREFBUF register config

Hello,I am using the STM32L071 with the latest STM32 studio software. I cannot find any sign of the VREFBUF configuration in the libraries (I need to enable the internal voltage reference for the COMP1 peripheral). I have found this article for H7 de...

Resolved! STM32L476: how to select ADC & ADC channel the DAC is internally routed to ?

Hello,I'm planning to use a STM32L476 to acquire approx 150 analog signals. For some reasons, I have to periodically check the justness of the ADCs.I read in the RM that it is possible to connect internally DAC to ADC but I can not figure out how to ...

STM32CubeMX H723 FW_H7 V1.10.0 Uart DMA can not work

I am working on STM32H723, I use STM32CubeMX and pack FW_H7 V1.10.0 to auto create code. I used 9 uarts, each have DMA for RX, and RXbuffer size if 512. I send data to each uart port 256 bytes one time. Then, the first time, uart report it received 2...
