Is synchronous data sampling of TIM.CNT and ADC.DR with 6 MHz possible with the usage of DMA1 & DMA2 on an H743?

Hi,I want to use an STM32H743 for sampling one TIM.CNT and one ADC channel synchronously and store the data of both peripherals in array buf_adc[5000] and buf_timcnt[5000]. Therefore I want to use the DMAMUX request generation and use LPTIM2 as trigg...

STM32L4S7VIT power consumption issue in power-down modes.

I am using STM32L4S7VIT MCU.I am using STOP2 mode to put MCU in power-down mode, for that, I am simply making all the pins as ANALOG except 1 interrupt GPIO PE0 and then calling STOP2 power-down function, but it is taking around 2 mA current it shou...

Resolved! Can someone please suggest me a way to build a binary (monolithic?) Image containing the code of both cores of a STM32H745, so that I can copy it with drag & drop in the windows volume "NOD-H745ZIQ (X :)"?

I can run the code for the two cores if I program them separately from the Keil, but I would like to generate a .BIN image to send to my client, who is doing tests on a prototype, with the code for both cores.I generate the .BIN with the "fromelf" pr...

HAL_UART_ErrorCallback not being called after overrun error

This is on a STM32F412RGTx.I just inherited a long over-due project based on this MCU. I've done lots of PIC and 8051 programming, but very little on an STM, or with the HAL.We are sending short commands to the MCU from the PC (ie, SET VAR1 1.234),...

Resolved! I2C DMA stall

I'm configuring i2c with dma using the registers directly. I'm sure I have an error somewhere but I don't have a great idea on where to go next with debugging. Sometimes my i2c transfer goes through expediently, but sometimes it has a long stall afte...

How to enable the ART accelerator on STM32F76x processors?

I'm wondering if the following is correct for using the ART flash accelerator on the STM32F7 line:Change linker script to use the ITCM instead of the AXIM bus for FLASH memory.In the startup code, enable the ART accelerator by setting the ARTEN bit o...
