I am developing a device using the nucleo-f429zit6 evaluation board as a reference. This device has an Ethernet communication function, and the Ethernet communication function was tested by directly connecting this device to the server using a cross-...
Hi, We are trying to run a signal integrity simulation of STM32H747IGT6 in Altium Designer. However, all of the reflection waveforms for signals driven by the device are around 0 volts (basically noise, no driver). We've noticed there is some errata ...
Hello, I have this code // Initialiser le bloc A fresult= HAL_SAI_Init(&hsai_BlockA1); if (fresult != HAL_OK) { return HAL_ERROR; } // Initialiser le bloc B fresult= HAL_SAI_Init(&hsai_BlockB1); if (fresult != HAL_OK) { r...
Hi! I am configuring DMA to generate a PWM signal to control addressable LEDs with an STM32563VGTx MCU.My issue arises when generating the PWM signal using DMA. When calling the "HAL_TIM_PWM_Start_DMA" function, it executes without any errors, and th...
VSCode is gaining in popularity at work and so I had a requirement to use it as the development platform for an ST mcu based project. I have very little experience with vscode and as I was unable to find an answer to my problem I thought that I would...
i use nucleo-f446ze learning how to use STM32F4 stdperiph，but in STM32F4XX_GPIO.h，GPIO_MODE only have 4 mode，GPIO_Mode_IN = 0x00, /*!< GPIO Input Mode */GPIO_Mode_OUT = 0x01, /*!< GPIO Output Mode */GPIO_Mode_AF = 0x02, /*!< GPIO Alternate function M...
Hello,upfront, it might be an incredibly dumb problem on my behalf as I am fairly new to this.For a couple days now I have been trying to read out the voltage through the onboard ADC configured for 12 bits but all I am getting back are values in a si...
Hi community,I am using STM32H747I-DISCO board and I configured external SDRAM as dynamic data memory in M7 core by calling the SystemInit_ExtMemCtl() function in SystemInit() function, it is working fine but when I tried with the M4 SystemInit_Ext...
Hi, everyone.When implementing a sort of delay function using Timer2 to have a more precise time control, while putting the MCU in power-saving mode, I noticed that the division performed to the APB1/2 clocks does not correspond to what's programmed....
Hello, we are using the saleale logic 8 to read data transfer between an STM32 MCU and an IC through SPI (ADS8166 ADC).The CLK frequency is 1.5 for the SPI configuration with a prescaler of 2 so at the end we have CLK of 750 kHz. For some reason SO...
