STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on October 17, 2017 at 10:31Hi.I'm not sure whether one IRQ handler can handle multiple ports.For example, If I made one EXTI3_IRQHandler(), then I want to connect external interrupts PA0, PA1, PA2, PA3 to EXTI3_IRQHandler().Is this possible ...

Posted on October 17, 2017 at 06:33HelloI am using STM32F746-Discovery.I run USB in high speed mode.Internal DMA is enable.But, if I use ICache and DCache my host is't initialization.Who will tell me what the problem is?What am I doing wrong?Alex
Posted on October 14, 2017 at 22:18How to manage: I2C_TransferHandling() for accessing high sector (>255 bit) of a 24c04 eeprom?In a selecting device I'm not capable to modify 0xA0 to 0xA1 for settings A8=1 and access to 256..512 bytes of eeprom.I'm...
Posted on January 18, 2017 at 16:20Hi,im using a STM32L476RG and want to interace an extrenal RTC via I2C.cube = 4.19.0lib L4 = 1.6.0 hi2c1.Instance = I2C1; hi2c1.Init.Timing = 0x10909CEC; hi2c1.Init.OwnAddress1 = 0; hi2c1.Init.AddressingMode = I2C_...
Posted on October 17, 2017 at 03:14I got a ST32F769NI-EVAL and trying to send serial data through UART7.I've found the right setting using PB4 as Tx and set it correctly.I use internal JTAG(not using ST-LINK) so I can use the PB4 pin as Tx.But I get...
Posted on October 17, 2017 at 00:54 I cant get the STM32F746 timer tick interrupt to work even though I have followed the chain to the tick ISR. Comments in the code are a bit unclear too. /** @addtogroup HAL_Private_Variables * @{ */ __IO u...
Posted on October 16, 2017 at 22:39Hi, I've found a brillant OCR source code made for the STM32F429-DISCO board. I had to rebuilt the project, using the KEIL V5, because the original source code doesn't bring the project files or the linker files. ...
Posted on October 16, 2017 at 21:24Hello All.I am new to STM32F microcontrollers, though I have worked with Freescale/NXP Kinetis ARM processors for quiet a few years.I am trying to get and external interrupt (on port C bit 13) to work on a 48 pin ...
Posted on October 16, 2017 at 21:08After enabling the hardware IWDG, I noticed that on subsequent SW programmings, I always get an immediate single IWDG reset event. After that reset, the system boots, but it seems to boot several times faster than ...
