Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I am setting up I2C communication between a master board (STM32H753I-EVAL2) and a slave board (NUCLEO-H753ZI). At the master board side, I use "HAL_I2C_Master_Seq_Transmit_IT(&hi2c1, 96<<1, (uint8_t*)gTxBuffer, 4, I2C_FIRST_AND_LAST_FRAME)" to start ...
Hello,I am trying to implement 2 separate UART channels on the single port. I have initialized the two UART channels and have connected the TXs and RXs of the two channels with each other. (Image attached)When I run them separately, they work just fi...
STM32F411. Line 2693: srcclk = __HAL_RCC_GET_I2S_SOURCE();That macro calls "READ_BIT" on the I2SSRC register bit.It does NOT shift it right 23U.The function then compares this to 0 or 1.FAIL.Result. I2S cannot be configured to use an external clo...
Hi all,I am using FileX with my Nucleo-U575ZI-Q, and I want to be able to open multiple files at the same time.Now every time I try to do this, the first file opens fine no problems but when I try to open another file (without closing the first) I ge...
Hi All: I am having trouble figuring out why exactly this behavior happens randomly and how to fix it on NUCLEO-H743ZI2. Any help would be appreciate it. I went through some debugging. I think the issue could be the following. I attached my ma...
After two days of trying, I decided to ask.I have this STM32H747I-DISCO and B-LCDAD-HDMI1. The examples that are from the site given below the board and consist of programming a single hex file work (STM32H747I-DISCO compiled demo binary), without th...
I have an ADC input that is read continuously and put in a buffer by the help of DMA. This is my buffer:uint16_t adc_buf[ADC_BUF_LEN]; //ADC_BUF_LEN = 1The value in the buffer is replaced continuously by the NEW sampled value from the ADC.I wa...
Hello,I have been trying to establish the UART communication using DMA. To implement that I referred to https://community.st.com/t5/stm32-mcus-products/stm32h7-uart-dma-receive-unknown-length-of-data/m-p/86869#M11292 post. I am trying to implement DM...
I am trying to change the PWM duty cycle of timer3, channel 1 from the period elapsed ISR of timer 6. This seems to cause the chip to crash. I can confirm that:- timer6 is properly configured and interrupt fires appropriately.- timer3 is properly con...
Hi,I want to split the .BIN file because it is too big... Here is the size of the files :.BIN size : 2.13 Go.HEX size : 30.5 Mo.ELF size : 11.4 MoHere is the memory used :I am using an USB flash drive to update my system program. I know I need to spl...
