I'm using the project "SPI_FullDuplex_ComPolling_Master" in P-Nucleo-WB55.Nucleo/Examples_MIX/SPI in FW version 1.6.0. Works fine on the nucleo board. I've ported it to my board which uses pins PB5, PB4, and PB3. I'm using a crystal on my board. I di...
While trying to read ADC value over voltage divider I accidentally connected not divided voltage to ADC pin. That was about 10V and with burnt smell I promptly intervene and cut the connection. The board was hot but I could touch it. After that I pu...
Hi all,I am considering the STM32L073RZ for a low earth orbit application. Would this MCU be suitable for the following operational environment?Altitudes of 590 – 630 km.Temperature environment range is -40°C to +70°C.Total Ionizing Dose (TID) exposu...
Hello everyone, I have medium level in stm32 mcu's like using adc's, timers and also HRTIM peripheral in 32f334 and G4 series but I can't figure out the optimum way to generate three level spwm waveforms for using with NPC inverter that I'm designing...
ref: https://www.st.com/resource/en/application_note/dm00110292-implementing-an-emulated-uart-on-stm32f4-microcontrollers-stmicroelectronics.pdfDue to pin restrictions, I've forced to send data on two GPIO pins not wired to any uart on the 152. I've ...
Hi, I am developing a product which has a LCD. So I am using STM32F767zit6 MCU and MT48LC4M32B2 SDRAM on my custom board. I want to know is there any tutorial or example there which i can referrer to generate code form cubemx and test my SDRAM. I hav...

Hello,I'm trying to control the boot behavior of my STM32L412 development board which has a floating BOOT0 hardware pin.I'm trying to clear the SWBOOT0 bit in FLASH_OPTR using firmware. So far I am able to unlock the register and clear the bit. Th...
Hi,I have some strange problem with UART printing. It does not work when Interrupts are enabled and Link Time Optimization is used. Or rather the UART prints the first character and then seems to get stuck. If I either disable interrupts in the code ...
