Hi, I had a weird issue with an STM32F334 MCU. A pin was configured as Open Drain - this pin is used for falling edge interrupt and pulled up by a different section of the design. But I had issue today with the operation of the pin and realised the M...
Hi,I'm trying to use STM32F407 to develop bluetooth audio device. I use the cc2564c bluetooth board and CC256XEM-STADAPT board made by Texas Instruments. Now I need to use UART2 to connect the STM32 board with PC, but the PA2 and PA3 pins are used b...
Hello, I'm using the demoboard (B_U585I_IOT02A) in order to read an analogic input (between 1V and 2V for my tests) and I'm currently trying to use the ADC. I say "trying" because, for now, I still haven't been able to read the values correctly. Fo...
We are using I2C channel 1 for EEPROM and RTC (Semophore used for exclusive access) and I2C channel 2 for Touch controller. Both I2C runs at 400KHz. Everything works normally, Suddenly I2C channel 1 becomes busy at random time. It is really hard to r...
I am trying to get LM35 temperature sensor value using STM32F411RE. When supply voltage fed to LM35 is 3.3 V, the correct digital data is produced. But when 5V is fed as supply to LM35, the digital values produced are the same as those when 3.3V is s...
HiWe are using the STM32L4S7AI. We have USART2 configured as 9-bit data.We are using the HAL and have been using 8-bit HAL on many STM32 for a while... this is our first 9-bit data use.We set UART_InitTypeDef.WordLength to UART_WORDLENGTH_9B.On the w...
There are two variants, STM32H7B3IIT6 without SMPS and STM32H7B3IIT6Q with SMPS. What are the differences between using or not using SMPS? Why is it preferred with SMPS?
Hi team, I am trying to generate I2C driver code using STM32CubeIDE, to understand perpheral functions. I was successful in generating the code but i cant find the functions which I am looking for like I2C_Init(), I2C_cmd, I2C_GetFlagStatus() ...Coul...
