Hi,now I'm implementing i2c with 1 master(U575ZI-Q) and 3 slave(L432KC) boards. master transmit dataBuf to slave HAL_I2C_Master_Transmit_IT(&hi2c1, addr<<1, dataBuf, sizeof(dataBuf)); and Slave receive it.HAL_I2C_Slave_Receive_IT(&hi2c1, dataBuf, siz...
I'm using UART to send message. To prevent data race, I'd like to first disable then enable transmit complete interrupt when trying sending more data. But enabling transmit complete interrupt generates an unexpect interrupt. static volatile bool g_s...
STM32H7 can support SPI communication, Parallel communication, GPIO analog SPI communication, but can it support TTL, SDR CMOS, JESD204B protocol communication? Or what should I do if I want STM32 to implement these protocols?
I am using the USB port on a STM32U595 in device mode only. I am not using a type-C interface with a CC controller. I see that the NUCLEO144_Q with STM32U575 divides the USB VBUS input and connects it to PC2 for use as VBUS_SENSE.[Q1] Do I need to co...
Setup Info:Compiler: IAR EW for Arm 9.50.1, Debug build configuration, High optimizationMicro: STM32H503CBU6 I am running into an issue where when I am trying to copy the CR2 register from I2C1, it copies the wrong value and the addresses of my other...
Hi,I am using the STM32H750B-DK board and would like to use the LCD and touch screen in my project. I have been looking at the existing LTDC_Paint example (STM32CubeH7/Projects/STM32H750B-DK/Applications/Display/LTDC_Paint at master · STMicroelectro...
I have a board design based on stm32L452 , USB gets recognized on a windows PC and I can talk to the device over any software like putty and a Test software sees the com port and can to the device. However in Android (Iam using samsung GalaxyTab A8)...

I'm working on stm32f103 I2C peripheral. I've one stm32f103 master and another stm32f103 slave. The master should send some text to the slave, but start condition never generates. The BUSY flag is set as soon as the peripheral is enable and the progr...
