While output data from DMA to SPI it should be able to use two buffers. One for the current transfer, one to write data.But how do I switch between the buffers?#define BUFFER_SIZE 10 uint8_t txBuffer[BUFFER_SIZE + BUFFER_SIZE]; HAL_SPI_Transmit_DMA(&...
we are using stm32G030, we need to update firmware using I2C, we are using st-link v3 and we connected (SCL,SDA,GND), opened cube programmer to update firmware we selected I2C and and given i2c address as 0xAD/0xAC but we are getting I2C_BRG_ERR,wha...
I used 1.7version now i renew my project couple of days agoI guess problem with 1) LWIP/TARGET/ethernetif.c, 2) LWIP/TARGET/ethernetif.h, 3) LWIP/TARGET/lwipopts.h4) stm32f4xx_hal_eth.c5) stm32f4xx_hal_eth.hI got searched lwip thread i think new ve...
hey,I went through all possible data sheets I could find did all the required things but my Nucleo still won’t be programmed with uart.I have put boot0 on VDD pin next to it. For confirmation I also put PB2 (nboot1) on ground next to it.I tried power...
Hello,I would like to use the TCP/IP protocol (with LwIP, HAL library, without freeRTOS) in a project but I face some portability issues.I'm starting with TCP echo client example as in chapter 6.1.1 of UM1713 document.I used the 1.26.2 version of STM...
Hi.I am using a STM32F469I-DISCO and I am trying to read/write on a SD card. Here's what I did on cubeMX:SDIO -> SD 4 bits Wide Bus -> enable SDIO global interrupt -> add SDIO_RX and SDIO_TX as DMA settings -> GPIO settings set all pins except SDIO_C...
Hi there !I want start to write my own library, and step by step stop to use HAL library. Please some one know where i can find information, tutorial , or know some good book and whenre i can buy ? or webbinar ? Thank you Sergio
I've extended the USB-CDC example using Cube IDE to report serial port line state -- Ring, etc. My example works on STM32F1, however, it does NOT function correctly on STM32F4. Here's the meat: /* USER CODE BEGIN PRIVATE_FUNCTIONS_IMPLEMENTATION */ ...
