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...
Hi,I use Linux as a development environment for STM32F429. I've created several Makefile files for my project and I'm able to compile it. Now I'd like to flash project's output binary file to STM32F429. I know that it is possible to mount STM32F429 ...
Hello,I am wanting to do flash via dual boot option on a STM32L476RG board using an external board NUCLEO- L476. when I am trying to change the option bit via program in which i am using HAL_FLASHEx_OBGetConfig and HAL_FLASHEx_OBProgram in our main p...
Posted on April 05, 2017 at 12:48HelloI'm trying to read data from a GPS module that send packets with different lengths. I connected the rx line to another pin and enabled an interrupt on it, in this way I can 'timeout' the end of packet (packets a...
HelloI am implementing I2C transfer with DMA in stm32.Processor: stm32l152rdt6DMA Configuration:I would like to continuously receive 3 bytes from master, so I use circular mode.NVIC Configuration:I2C Initialization Code: hi2c1.Instance = I2C1; hi2...
We've also had problem with STM32L496 to implement dual-bank boot but it had been resolved by workaround. But for STM32L4R5, it is still not working.
In the STM32H743 errata sheet (ES0392 revision 4), section 2.3.1 “Conversion overlap may impact the ADC accuracy�? leaves me with three questions:If I am reading correctly, this means that running conversions on two different ADCs, from two different...
For each microprocessor of the ST series - there is public documentation in PDF format, for example DS10916 (pages 76-87). I want to make my own format for describing AFxx contact states. When you try to convert a table from PDF to text or Excel tabl...
Hello,STM32F4 and F7 have a VOSRDY bit in PWR->CSR. Documentation about the bit is nearly not existant. On a F4, while still running on HSI, I changed the VOS setting. Waiting for VOSRDY in that state never succeeded. Looking for that bit just before...
I am new to STM32 products and development software. I have purchased the STM32F303RE Nucleus-64 Eval Brd. I'm also using SW4STM32 IDE as there are more examples. I have had some success, I still have some fundamental questions. I also downloaded and...
Hi,I am using STM32F746 series MCU.1) After executing SCB_DisableDCache(), the CPU resets.2) The CPU starts up after repeating the reset multiple times.3) This symptom does not occur when debugging with JTAG (ST-Link) connected.Could someone know thi...
