para aplicar i2c alternate function open-drain GPIO_InitStruct.Pull = GPIO_PULLDOWN o should be GPIO_PULLUP (what diferencetween both) and uart alternate function push-pull should be pull-up or pull-down what diferencetween both?
Hello,I am relatively new here and would like to try to design a STM32H747AI board with LiPo battery power supply for wearable devices with features like OLED microdisplay, WiFi+Bluetooth and GNSS module. Since I would like to run a GUI on it with sm...
Does the STM32 NUCLEO BOARD STM32F446RE have internal pull-up resistors for I2C communication?
1. I am implementing a custom extended kalman filter function. The program on running hits HardFault handler on the 4th iteration (prediction function).2. Cortex-M4->CFSR = 0x8200 (BFARVALID=1)3. BFAR holds : 0xa5a5a5a5I am not able to understand whe...
Posted on November 11, 2015 at 17:50 Hi every one, especially Mr.Clive, today i have problem with CAN FILTERS i want to allow all IDS from 100 to 1FF in other words block all messages after 0x0200 here is my code, Please help me, Thanks in...
I bought STM32L073RZT6 and LAWAN1 expansion board, will STM32F103RB and LAWAN1 be compatible?
When used on STM32L4xx platforms (and possibly others), with flash configured for single-bank mode, the EEPROM emulation library (https://www.st.com/en/embedded-software/x-cube-eeprom.html) miscalculates flash sectors which causes silent erase failur...
Hi, I am using the STM32L45 series in my HW and I wonder if it can support I3C protocol?If not, is there another compatible MCU you would recommend?Thanks, yy
I'm trying to do a FW upgrade on the STM32F427IGH6 chip, having an Infineon XMC4800-F144K2048 chip as the master and the STM chip as the slave. They're connected via I2C; I've confirmed that the lines are connected properly, as I'm able to send data ...
I can't seem to connect to my STM32F401RCT6. This is the schematic below and all the jumper wires are working. Can anyone spot the error?When i try to connect to it i get the message 'No device found on target'
