STM32G031K8 consumes 100uA in Stop1 mode
Hi,I am currently working on the firmware of a PCB with an STM32G031K8T6 as the MCU, supplied by a 1.8V voltage.When I enter Stop 1 mode, the consumption of the MCU drops to 100uA, instead of the 7uA stated in the datasheet.The app_stop function is a...
Unable to do communciation between FDCAN and Classic CAN
Hi everyone, I’ve been stuck on a CAN communication issue between two boards: STM32F429 Discovery (Classic CAN) STM32H743XIH6 (FDCAN) I’m trying to establish CAN communication between them. Currently, the F4 board can transmit and receive data cor...
Resolved! Is STM32G4 FMAC X1 vector\non-circular mode documented\supported?
I have multiply\accumulate operations that I want to streamline by using the FMAC. For my application I will be loading the X1 buffer by DMA from peripherals and I don’t want to use circular mode. Documentation mentions ‘vector mode’ which matches wh...
lost access to STM32G030 micro
In a recent design I needed an additional pin and I configured the PA13 / SWDIO pin as a GPIO input.All going fine, code works, but then this happened: After I program the chip in automatic mode and set the option byte rdp to 0xBB I can't connect aga...
Resolved! Pins assignment of OCTOSPI PSRAM (APS12808L-3OBM) to STM32U575 GPIOs
Hi, We are planning to use PSRAM chip apmemory (APS12808L-3OBM) with STM32U575QII6. Please check pin assignment from STM32 to PSRAM chip And also please share the schematic and layout guidelines for STM32U575QII6 OCTASPI to PSRAM chip integration. ...
STM32H7's I2C4 using BDMA not triggering Complete Callbacks.
I'm using an STM32H725 to communicate with an i2c sensor. I'm using the I2C4 bus with the HAL DMA functions. I also enabled the BDMA channels for the rx and tx and respective interrupts. The problem is that the complete rx/tx callbacks are not trigge...
Resolved! I cannot get any useful printf() info from SWVITM data console in STM32N6570-DK. The displayed info are messy symbols.
i use STM32N6570-DK to do a simple project but i cannot get any useful info via printf() on SWVITM data console. (1) I add some code in systemcall.c for printf() on SWVITM data console or UART1 via a "define" in my main.c. (AS many professionals sugg...
confirmation for the LPTIM present in the STM32C011J6Px
Now I want to know whether the STM32C011J6Px has a Low-Power Timer (LPTIM).Currently, we are planning to use the STM32C011F6P6 MCU in STOP Mode 2. Since we do not have any external pin interrupt available as a wakeup source, we are planning to use th...
Difference in utilization factor for STM32H753 and STM32H743
Hi, I am using STM32H743ZI Nucleo 144 board for one of my application. As per the observations I got the utilization factor with STM32H743 is 35% where as with STM32H752 it was 60%. We have not initialized any crypto or secure features on STM32H753 b...
