Resolved! Problem with ADC on B_U585I_IOT02A
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...
STM32H743BI, I2C becomes busy after two hours or five hours randomly. Some times there is no issue.
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...
Resolved! STM32F411RE ADC: wrong results with 5V supply to LM35 temperature sensor.
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...
Resolved! 9-bit UART data not as expected
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...
Resolved! Differences between with and without SMPS
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?
I2C driver code generation from scratch.
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...
Is it correct that HAL_UART_RxHalfCpltCallback and HAL_UART_RxCpltCallback are invoked even when there is nothing connected to the Tx and Rx pins of my microcontroller?
Hi community!I would like to understand if it is normal that when I use DMA method to receive data the callback related to this method are invoked even when there is nothing connected to the Tx and Rx pins of my microcontroller.I'm using a NUCLEO-F30...
How to find and choose input capture filter sampling frequency to improve the signal?
Dear all,How to choose the Input capture filter sampling frequency? Is there any method to choose the appropriate value for ICxF bits or do we have to try and find the best value? Anyone has experience with this topic, please share the experience you...
