I am using STM32L4S9AII6 MCU.I am exploring options to ensure that certain outputs are forced to a known safe state during power up. I want to be able to take advantage of the MCU's built in GPO pull-up and pull-down configuration features, but I am ...
Hello all.We have developed in the past some devices using the STM32F4 and F7 families, with no issues using ADC+DMA+Timer Triggering with no effort (mostly tweaking the examples provided by ST and using the ioc Cube files).However, we are trying to ...
I am trying to use bitmapped structures to send data to an i2c DAC. I defined the fields as:typedef enum { mcp4726_command_code_write_volatile_dac_register = 0b000, mcp4726_command_code_write_volatile_memory = 0b010, mcp4726_command_code_...
Hello allI have a custom STM32L496RGT3 based board which I've configure to run at 64MHz off the HSI using CubeIDE:void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Conf...
Hi!I use SRAM 1 (0x30000000 - 0x30003FFF) in D2 domain for USART2, USART3 DMA buffers. All work clean. If I use SRAM2 (0x30004000 - 0x30007FFF) just after running debug it's all right. But after "Reset chip and restart debug session" the first access...
CPU hangs when calling I2C_WaitOnFlagUntilTimeout because I2C DMA interrupt handler has higher priority than system handle, so that tickcount cannot hit the Timeout. How can I resolve this trouble without consuming too much CPU ? I saw some topics ab...
Hello. I am writing an SPI driver for STM32F407 Microcontroller to control the resistance of the MCP410 chip.The datasheet for the chip can be found here:https://ww1.microchip.com/downloads/en/DeviceDoc/11195c.pdf The I use a cheap logic analyzer tog...
External 32.786KHz crystal is connected to the terminals PC14, PC15 and 6.8pF, NPO Capacitors connected between crystal and GND.Battery Back-up is provided.Configured using the STM32CubeIDE (STM32CubeMX) -> Clock Configuration to use LSE (32.786KHz)A...
