ADC Vref and External input in STM32L053R8
Can we use the Internal ADC Vref channel and External analog input channel simultaneously in STM32L053R8 and get data using DMA.?

Resolved! inconsistent behaviour in TIMER and CCxR interrupt
Hi, I'm using an STM32L053R6Tx chipI've implemented at TMR2_interrupt hander it gets triggered on ARR overflow and CC1FI'm using the interrupt to trigger a GPIO output to work like a PWM the- GPIO is high when CNT is less than CCR1- GPIO is low when ...
STM32U575 Nucleo Board SMBUS
I'm new to using the Nucleo environment I am not seeing any activity on the PB10 and PB11 when using the SMBUS_TwoBoards_ComIT_Master example, when looking at those pins on a scope. I only have one board currently. - Board: NUCLEO-U575ZI-Q (embeds...
Resolved! Two STM32 - UART communication
Hello,I've been doing a small project lately and ran into a problem in one part. I have two STM32 microcontrollers and I want to communicate both of them with eachother over UART. One of them is designed to send a fixed array of 6 charactersuint8_t k...
Resolved! STM32F7 crash on HAL_UART_Transmit
Hello, My STM32F7 crash after Reinit the UART : - I have an UART for my RS232, and I can communicate to 2 devices by this RS232. So the customers choose on which device he want to send data, then I configure internals variables and the UART baudrate ...
Resolved! Ethernet don't work with VOS1or2 settings of STM32H745IIK6 (customer board).
Hi community,I have a problem where Ethernet does not work when VOS is set from scale3 to scale2 or scale1 on a customer board.Please help us solve the problem. Clock and peripheral settings use code generated with CubeMX v6.9.1. The CPU is STM32H745...
STM32H723 ADC3 with VREF+ at 3 v
All:We have a custom board with STM32H723 where VREF+ is set to 3 volts.When I feed ADC3 input 2 with a value of 0 volts, I get 118 counts on the 12-bit ADC, 1.48 volts gives 1385 counts, and 2.95 volts gives 2600 counts.Earlier work with Nucleo boa...
Resolved! Power consumption of 6K vs. 12K SRAM in STM32C011F6 vs. STM32C031F6
Hello,We are using the STM32C0 in a low-power application. We initially selected the part with 12K SRAM in case we needed to use more than 6K, but after development have found that we can make do with 6K. I am curious if there is any power savings ...
STM32H735-DK: SMPS vs LDO interesting observation
Heyho,I just made an interesting observation on the STM32H735 Discovery concerning the internal core power supply.I'm working on an ethernet bootloader for my custom board using an STM32H733, which has no internal SMPS, only the LDO.As I do not yet h...
Resolved! CubeMX STM32L4 code generation question
Hi folks,I use MX to generate a code for STM32L4. I noticed, when I configure timer in one pulse mode, I cannot set OC CH1 in PWM mode with CubeMX. I could set it manually after code was generated, but it would be overwritten if I run MX one more tim...
