Hi.I init global array DMABuf[33] = {0}; According C++ standard it must be filled zeros.DMABuf placed into SRAM1(2) i.e. SRAM D2. Immediately after reset the buffer contain zeros. After initialisation DMA, buffer and all SRAM D2 contain random number...
Hello,for a switched capacitor ADC with differential inputs, I would expect no limits on common mode voltage as long as input voltage is in the GND/VDDA range. However STM32 ADCs only allow a small range of common mode voltage around (Vref- VDDa) /2....
STM32L412KBUx on NUCLEO-L412KB, STM32CubeIDE, Version: 1.8.0.I'm trying to use TIM1 to measure frequency of an external input signal connected to PA8. I'm confused by the choices in CubeIDE. In Pinout & Configuration, TIM1, Channel 1, I selected Inpu...
I have set up an SPI interface between Nucleo-STM32L476RG and TI CC1200. Working in STMCube IDE and mostly using MX to generate drivers for SPI2. The SPI interface works and I am able to send comands and receive regster values to/from CC1200 however,...
I started a new project using an STM32G473CB in the QFN48 package. I've used this and other G4 chips for many other projects and never encountered this issue. This issue occurs with all 3 flash size variants (CB, CC, and CE).I've replicated this issu...
I create a custom board to use PT4115 to control LED. This PT4115 can be control with PWM or external DC on DIM pin. According to spec, the DIM range is 0.3-2.5V.I tested the board by I short the DIM pin to GND and the LED turn off.So it show the boa...

Hello ST community!I'm working with the STM32L152C Discovery board and would like to create a simple USART example. I have developed USART drivers in the past, but this time they are not working with the disco board. It is possible that it has to do ...
