I have a requirement for receiving some long USART packets. (200 to 300 bytes). They can be of variable lengths. I did not want to poll or trigger interrupts for each byte and watch for a Stop byte symbol. But been trying to get the Idle line or Rece...
I have been trying to learn the STM32 for the past week. As someone started with Arduino, this is quite frankly overwhelming to me.Anyways, what I couldn't wrap my head around is where do people find all the reference for the callback function. I'm c...
Hello,As you can see, based on datasheet, the input frequency of Timer 2 is 36Mhz. I have attached 25Mhz crystal to my MCU and here is clock and timer configuration. I need to have 30mS interrupt but I get 16mS.void CLOCK(void){ RCC_HSEConfig(RCC_HS...
Hi, I am using an STM32L4 MCU and I need to make the COMPx_OUT acting as a retriggerable monostable output. I know I can use timers as blinking source for COMPx_OUT, but this would not help, and as far I understand, the only way to solve my problem ...
if(low_power_mode == 1) { standby(10); HAL_RTCEx_DeactivateWakeUpTimer(&hrtc); }void standby(int seconds) { /* Clear all related wakeup flags*/ __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WUF2); rtc_set_wake_up_timer_s(seconds); HAL_PWR_Enter...
I am currently developing on a NUCLEO-G071RB board and I need to generate sine waves with frequencies in the range 1Hz - 11kHz. My project requires the step between the frequencies to be 1Hz. It doesn't have to be precisely 1Hz but it has to be close...
Chip: STM32G474I have a ADC chip that offers SPI-compatible interface, it could achieve below functions in picture.I tried use QUADSPI to achieve that without instruction, address, alternate, dummy, but only DATA with indirect-read mode, but couldn't...
Hello, I'm trying to use arm_math.h in the m4 core of an stm32h745, but i get a bunch of really weird errors that seem to indicate that somehow the project configuration is wrong? I set the project properties to Debug_CM4 ( active ) and define CORE_C...
I want to manipulate the program counter in an assembler function by branching down a list of instructions by a programmable amount.syntax unified .global myasm myasm: PUSH {R0,R1,r2,r4,R5} ADD R15,#4 is rejected by the assembler.syntax unified ...
