Hello, I am using STM32F429ZI Freertos+TCPIP+TFTP . Ethernet works smoothly but after addition of small code which includes some global array of 2KB it does not give ping response. when I uncomment the global array then again it works properly. What...
Hi All, I'm using stm32h753, no LWIP project. Eth Tx is not working. HAL_ETH_Transmit - keep failing with DMA transmission - I have seen few posts about that issue - I tried all the solutions I saw - none worked...Any help is most appreciated!
I have a STM32H735-DK and I'm trying to get an audio data from codec WM8994. I programmed the SAI1-A to be SLAVE_RX while SAI1-B is MASTER_TX. I programmed the codec input INL1. Everithing seems to be fine, the DMA fifohalffull and fifofull are gener...
Hi, I am working with a STM32H743 and I am trying to use USB OTG FS with the best clock configuration possible. I would like to have a SYSCLK at 480MHz and use the USB OTG FS with the external clock source HSE at 48MHz.The frequency of the external c...
Hello,I wanted to use the CORTEX_M4F_STM32F407ZG-SK demo of free rtos with stm32f401cc. In the past I have used this demo with stm32f405rg, I have changed the PLL setting for 84Mhz as:// in stm32f4xx.h#define HSE_VALUE ((uint32_t)25000000)// in syst...
How shall I get the configuration details for each module . If DFSDM what are the design parameters, RTOS Timer information and algorithm used etectera
Hello,I am working on STM32H745IIK controller.I am enabling the FS and HS USB configuration.This is very Important connection ,the USB HS is used for accessing the data come from the PC application and the data comes in veryhigh speed.FS mode is use...
Hello Everyone. I'm a student and learning ST nowadays.Forgive me for my childish question but I really don't get it.HAL library's functions are usually returns a value of result of the process.For example, HAL_Init func returns HAL_StatusTypeDef val...
Dear experts,I'm having a weird issue with SPI initialization on STM32H743/753 .The device connected to the SPI master needs HIGH clock polarity (CPOL). So we clicked this in CubeMX, and the generated code indeed has "hspi1.Init.CLKPolarity = SPI_...
