Hi, I'm trying to write i2c ISR by myself with LL. But after START condition address don't transfer(I see it in my oscilloscope), although I write to I2C1->DR address of slave and read reference manual with attention for proper handling.I generate in...
Hi. I hope this is the right place for such a question about USB communication, I am still new to STM32.I have been trying to send a message from my STM32 board (STM32756-EVAL) without using UART, but the OTG USB. I have been trying to set up my PuTT...
Hello,I'm interfacing the KTD2026 RGB sensor.Writing to the device's registers works with normal HAL I2C functions.The problem i'm facing is reading the device's registers which from datasheet should be done the following way:I have tried both HAL_I2...
Hi,in RM STM32G4 (I use Rev. 7, page 1882, Figure 648 "Transfer sequence flow for I2C master transmitter for N>255bytes":The "RELOAD=0" info in last box at "N<256" is wrong.It must instead say RELOAD=1, AUTOEND=1 (otherwise Stop bit will fire immedia...
We have a project on an STM32H750 using FreeRTOS and I am trying to access an I2C device after the peripheral inits but before the FreeRTOS init and scheduler start in Main.c but I get no interrupts from the I2C port. I have checked that the interrup...
Hi,I use the NUCLEO-F091RC, STM32CubeIDE with the MCU Package 1.11.3 and FreeRtos.The I2C1 is used with an Eeprom. So I would like to use the function HAL_I2C_Mem_Read_DMA as it is shown for example STM32Cube_FW_F0_V1.11.3\Projects\STM32091C_EVAL\Exa...
This is more a bug report than an actual question.I have experienced a wrong behavior of the I2C driver of STM32H743ZI MCU (Nucleo board).What's happening? The driver is simply dividing by 2 the slave address passed as a parameter to the function HAL...
I am currently using the v1.6.1 of STM32CubeIDE and a STM32G473 MCU.I have implemented an I2C bus and have noticed a major bug with the I2C_WaitOnFlagUntilTimeout functions. There is this condition:if (((HAL_GetTick() - Tickstart) > Timeout) || (Time...
Hi,I studied the RM0091 (page 55). There UART, I2C is listed as supported interfaces for the internal bootloader.I was wondering why the CAN isn't supported. Is this the case?Thanks
The stm32-mw-openbl project supposedly implements the system memory bootloader available in all STM32 MCUs.However, there are some missing functions:The GetChecksum command is missing, but it is documentend for example in AN4221 (I2C interface for th...
