Open source Bluetooth Apps for Addressable RGB's
Hi all!Been a loooong time since I've been around forums, but I'm back!So a long time project I've wanted to do is coming back into my brain and I figure its time to start chipping away at it!I love RGB LEDs, especially the addressable variety, and I...
STM32F103C6 never enters interrupt handler and because of that holds SCL low because of RxNE is set, BTF is set and DR hasn't been read after first data byte received, stopping reception, why?.
I'm trying to send some data from master to a slave (the STM32F103C6) with HAL functions, with HAL_I2C_Slave_Receive() -no interrupt mode- the reception works flawlessly but with HAL_I2C_Slave_Receive_IT() -the one needed- the slave acknowledges its ...
STM32F103C, I2C_ErrorCode 4 with MPU6050
Hello,I setup i2c1 as per below. I am trying to get data from a MPU6050 device on I2C but I got error code 4.On the same hardware I tested using Arduino IDE and I can read data from MPU without problems.Can one support please guide me where should I ...
Setting register to restart counter
Hi, I have never work with register. I need to restart counter of LPTIM in stm32l431. The documentation says that I need to set a register to '1'. The image explain this. How I can do that? Thank's a lot.

STM32 communication with a display via I2C over DMA
Hi Everyone,My problem relates to I2C communication when trying to send bytes to a display on address 0x78. First I tried with the plain I2C HAL function(blocking), but I realised that the MCU gets frozen because of the huge amount of data to be sent...
