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 currently using STM32H723ZGT6 in my design. But because of the memory constraints for my application, I am planning to use STM32H743ZIT6 or STM32H753ZIT6 in my design. Please do let me know that these 3 MCUs are pin to pin compatible or a dro...
Hello All, I need to perform two separate tasks. First I need to locate an array of constant integers at the fixed address 0x8000 0000. I know this has to be done though the linker script. But I am a little out of touch with writing linker scripts. ...
HelloI am trying to implement CAN Wakeup functionality. I have used MCP2562 Transceiver. I understand MCU will PU the stdby pin of Transceiver before going to sleep. By Pulling Up stdby pin, Transceiver will be in low power state and can still send s...
I am using a custom PCB based on a STM32F446 MCU. I have followed step by step the ST's tutorial posted on their wiki: (https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step3_Introduction_to_the_UART), but I can't see the "Hello World" message once ...
Hello,currently I am using the NUCLEO-G474RE and the goal is to output a PWM signal simulating a sinewave. Therefore the duty cycle must continuously be adjusted.My issue is that I seemingly cannot do so.The Timer is configured as Timer D, TD1 output...
Problem is solved when I put termination resistors in the stard and end of the bus but when I do not do I have a strange behavior of the MCU that I cannot explain/understand.Below you see the screenshot of Yellow: RS485 bus, Blue: The RX Line on the ...
Hi, everyone. I am using stm32l496 and I my application requires me to keep all data in ram after reset. Now i followed these instructions in this link. https://interrupt.memfault.com/blog/noinit-memory it works, like I expected but the thing is I wa...
When debugging custom hardware with the STM32L431KC, the debugger gets stuck in the reset handler:Reset_Handler: ldr sp, =_estack /* Set stack pointer */And in the console it says:Open On-Chip Debugger 0.12.0-rc1+dev-00061-g5e9b46d77 (2022-10-...
Posted on September 14, 2017 at 04:50I'm developing the firmware for our custom CPU-Board with STM32F769NIH6, and checking RTC function using LSE clock. It seems working correctly, but can't see the waveform of LSE clock. Our circuit of the LSE cloc...
Hello Everyone I dont know if its the correct place to ask . We design a medical device where EN62304 calss C is applied . the standart says if we use an 3rd party software ( any library ) should be designed to use for medical devices. What about HAL...
