Brown Out Detection
I am using STM32F779NI for my project. My use case is I want to detect brown out reset after brownout occurs and system restarts.I am checking brownout reset flag using if (__HAL_RCC_GET_FLAG(RCC_FLAG_BORRST). But the problem is this flag is shared/c...
hi i am using STM32f746zg microcontroller with CANBUS i want to establish communication between CAN1 and CAN2 where CAN1(master) will send and CAN2(slave) should receive. CAN1 is transmitting perfectly but it is not receiving at CAN2 ..
can anyone help me with the code ....thanks in advance here is my codestatic void MX_CAN1_Init(void){ /* USER CODE BEGIN CAN1_Init 0 */ /* USER CODE END CAN1_Init 0 */ /* USER CODE BEGIN CAN1_Init 1 */ /* USER CODE END CAN1_Init 1 */ hcan1.Instance =...
Resolved! What is the Actual Input Clock Source for TIM1 of STM32F103RG?
I found from ref manual that the internal clock source for TIM1 is APB2 pre-scaled value.(Please see attached image).From CubeMx, I've configured my main clock frequency to be 48MHz, which is a PLL multiplied value from external crystal oscillator of...

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 ...
