Hi, I would like use the DMA functionality for SPI on my STM32F4. But all examples I have found are calling the SPI DMA Transmit Receive function in a while loop. But what would be a better way? I think that if I call the Transmit Receive function ...
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...
