STM32 MCUs Products

i have STM32F103C8T6 suddenly the pins of the MCU is not working. Are the pins fried ? The 3.3v or 5v pins does not work when I connect a LED using 1k res. But when i try to run the Blinky app in eclipse and choose the internal LED PC13 to blink it works

using internal Vrefbuf : HAL Code generation issue

I try to VREFPIN in internal mode (so VREFPIN is an output).Based on IDE STM32CUBEIDE 1.3.0 and using a STM32G071 MCU.The generated code is : void HAL_MspInit(void){ __HAL_RCC_SYSCFG_CLK_ENABLE(); __HAL_RCC_PWR_CLK_ENABLE(); /* System interrupt init...

STM32L562VET6Q stuck on interrupt enable

Hi,I'm working on una custom board with the STM32L562VET6Q, and i'm also using the STM32CubeIDE for developing and the STlinkV2 for debugging.I'm struggling because if any interrupt is enabled the program hang.I have made a simple configuration with ...

how to communicate between two cores with interrupt in stm32h745? please provide any example code

STM32L46 CAN : Data reception from remote problem

I am using STM32L46 CAN and trying to receive a chunk of data from the remote device .When its 73bytes I do not get any messages . I see the first 8 bytes in RDL0R and RDH0R. Also I see RF0R as 0 FIFO interrupt being enabled. I am using STM HAL APIs...

Hi, where can I find information about how to program an STM32 through the SWD interface? My objective is to program one stm32g0 through the SWD port without using a PC

Setting up GPIO and SPI for hardware slave select management. /NSS is never set to HIGH. Is there a bug?

I am writing a SPI driver for STM32L476RG, which is on a Nucleo board. First use: Communicate with an EEPROM to see how SPI works, logic analyzer records the bits. The slave seems not to react. I found out the /NSS pin is never High. As far as I get ...

STM32L4 Bypass Oscillator

Hello,I am designing a circuit that needs a HSE and a LSE oscillator for USB and RTC respectively, and need to solder it by hand. Would a bypass oscillators in a SOT23-5 package (i.e. the SiT2024BA-S2-33E-8.000000G and the SIT1630AE-S6-DCC-32.768G) w...
