Hi, I am using STM32L072CZT6 for my project. The device operates in two stages: It wakes up at scheduled intervals, save the number of interrupts received to flash , and returns to standby mode. During standby, interrupts wake the device, the count i...
Hello.I'm trying to use STM32 U5A5' SRAM (SRAM1,2,3,5) and I'm encountering some very weird behavior.When I use the entire aforementioned sram blocks, my mcu hard faults.uint8_t __attribute__((section(".TEST_Section"))) data[1024*1024*2];int main(voi...
Heyho,about VCAP / LDO connection in STM32H7 series without SMPS, for example in STM32H733ZGT6 (LQFP-144), when using the internal LDO for core supply.As far as I understand, the VCAP pins are for the connecting buffering capacitors to the internal L...
i have an issue with my timer interrupt that every 500 us happends and external interrupts (12EXTI) .when the timer interrupt happend , the external interrupts never execute.i dont know why this is happening.i mean it supposed to pending for other in...
Hi,Im using STM32L031F6P6 mcu for one of my project. Im also using IIS2MDCTR & LSM6DSV16BTR sensor.I need to find heading regarding that i have few doubts.1.Will STM32L031F6 mcu support mems1 package?if no could you suggest a mcu which support the sa...
USING MCU - STM32H743XIH6As per datasheet "STM32H743XIH6_Datasheet" page 139 it is mentioned that GPIO can sink/source 8 or 20 mA.When MCU will be going to source 8 mA and when it will source 20 mA?Is there any current control configuration inside MC...
hi i am saishiva i am working on the STM board from 10 days but i am not getting the clarity about the how to activate the RS485 using the modbus protocol can you pleaae help on that
Dear Sir,I have interfaced SDHC card 32GB of Sandisk with STM32L452RET6 microcontroller SDMMC1 peripheral in mode - SD 4 bit wide bus. In my device SD card as a Datalogger.Issue - When my device is working mean data is logging (Data writing in SD car...
I saw on NUCLEO-U5A5 schematics - there is a level shifter for signal T_VCP_TX:a bit obvious: if MCU jumper is set to run on 1V8 VDD - an external UART receiver (e.g. CP2102N) would not get anymore correct UART_TX signals (yes, it does not anymore wi...
Hello,which interfaces does a virgin STM32C0 in SO8N offer on the first boot for programming? AN2606 says USART1 and I2C1. In other cases, AN2606 adds a note when SWD does not work, but no such note is there for STM32C0. So, I assume SWD is supported...
