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 ...
Hi everyone, my setting looks like this:CPU CLK: 480MHzAHB CLK should be 240MHz (I'm not 100% sure)Timer CLK 120MHzInputCapture Channel: 4 (2 direct, 2 indirect)I generate 8 short pulses each about 30ns. I use 4 InputCaptures to read those pulses. 2 ...
Hello,This is the first time I am using the STM32 MCU.I would like to know how can I re-flash a certain section of the internal flash memory (eg 1000h ~ 1200h) with NEW sensor coefficients while keeping the already flashed MCU firmware intact.Can I u...
Hi Thank you for having me here! I come from the AVR-Mega community and wondering about selecting a STM32 MCU. I needed more time to process between my input capture and USART and HDLC processing. Which MCU have 4 timers and input/output capture avai...
on stm32f105 launched CAN. With the transfer of messages, there were no questions, but there were questions about receiving messages from two CAN.the code is responsible for processing the messagevoid HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeD...
Hi STM32 community,I'm trying to process a UART string and interrupt when the full string is received. I'm having trouble receiving anything at all. To check that my serial terminal (PuTTY) settings are correct, I have tried HAL_UART_Transmit_IT(...)...
I am using a STM32L475 and plan to also use an STM32L451 processor, I am having trouble setting the RTC so that its in 24 hour mode. According to the datasheet setting a 0 to bit 22 of RTC_TR should set it into 24 hour mode but this does not seem to ...
Hi I am fairly new to SPI slave with dma on a microcontroller, I am wondering in firmware what is the process of implementing it? I have set spi1 up as spi slave and assign dma streams to it in the cubeide, but now that it is set up, how is the data ...
If anyone has a working support number would be a big help. My Question is on the STM32F411 the data sheets state many of the lines are FT 5 volt tolerant, other team members don't believe this and want to use level shifters, they believe as many l...
