STM32 MCUs Products

My Nucleo-64 with STM32L073RB required a hard reset after power up using an external Vin supply. I tried everything to fix it, cap on NRST, delays in firmware, nothing worked. Spent days on the problem. Upgraded ST-LINK firmware and VOILA! Why???

Hi, I am using a STM32F7508-DK board and I would like to use the following setup: use only one project instead of building and flashing 2 separate projects, is it possible?

As I said in the description, I would like use only one project instead of using 2 projects and. I've tried to use a single linker file and split it after the build using objcopy to obtain 2 separate binaries for internal and external flash, with no ...

STM32 F4 Timer Input capture

Dear community,I am trying to use a timer to see if there is no activity on a data line. However, it works not as expected. As you can see in the picture, the timer (yellow) gets interrupts when the signal line (pink) is changing. But no interrupt, w...

Error in the stm32l412 datasheet. The quadspi pin assignments are not consistent between the pin table and the AF table. In particular QUADSPI_BK1_IO1 and QUADSPI_BK1_IO0.

SPI Mater<->Slave communication problem (slave starts to send 0x0010 after some while)

Hello, I'm working on a project with 2 STM32F4 that are communicating by SPI. The Master (running on 168MHz) is sending packages with 10x16bit every 1ms and 5.25mBit/s. The CS signal is connected to an EXTi pin of the slave that calls a DMA SPI tra...

What are TIMx TIx[1..15] input signals?

TIM1 section figures 55 and 79 in G0 reference manual RM0454 Rev2 refer to TI2[1..15] as selectable sources for TI2 signal (see also TI2SEL register bits). It appears that TI2[0] is the TIM1_CH2 pin, but what are the sources for the TI2[1..15] signa...
