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 am trying to configure a UART communication using the LL but I am not really understanding, registers seem easier to digest to me but I am not finding any tutorials or examples online. Can someone provide me with please? Thank you!
I'm using BL-475E-IOTA2 board (STM32L475) which comes with MX25R6435F Flash chip. I'm trying to using Quad SPI to write and read to/from the flash chip. With free running the code(release mode):If I don't use DMA when writing to the flash chip, it ca...
Hello,we currently have a problem using PB6 of an STM32G474ME as FDCAN-TX: During Reset, it is pulled down to GND, which we attribute to the USB-C functionality. This causes the FDCAN-TX line to send a dominant signal during reset of the STM32.As per...
I have a board that is running well. There are about 50+ PCBs in production operating fine. The firmware is pretty complex, but the hardware relatively simple, just some SPI devices and some PWM outputs.I revved the board, and the new board doesn't w...
Hi,I work with STM32F412/STM32F413 processor. I have also external LSE.I have the next problem related to STOP mode and RTC.There are some scenarios we want the processor to go to sleep for x hours.The processor goes to sleep for 5 seconds, doing som...
I've used https://community.st.com/s/article/how-to-create-an-i2c-slave-device-using-the-stm32cube-library as the example codeand in the example the main program is:/* USER CODE BEGIN WHILE */ while (1) { if (Xfer_Complete ==1) ...
I am trying to connect LCD (SPI interface) to my custom stm32f030c8 board, PB13 -> SCK, PB15 -> MOSI (Transmitt only mode).I created a test project with cube configurator (attached a screenshot).I did not change anything in the generated code, just a...
Hi!I'd like to set a custom section in the linker script file to store firmware specific constant data. This section should be at the head of the firmware binary with a fix offset address. I was able to create a section at the end of flash area but t...
