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...
I am trying to communicate with a spectrometer sensor using SPI protocol. With SPI default settings, I am using both arduino and Stm32L476 nucleo boards. (8Bits, MSB First, CPOL Low, CPHA 1 Edge).I read multiple registers from the sensor using both a...
I am working on register level programming, and I have gone thoroughly the reference manual it just contains about the features of the peripherals and registers and something about its working so how can I program if it does not contain the procedure...
