Problems with DFU bootloader for STM32G431
I want to program my STM32G431-Board with the DFU bootloader. I’ve already set the configuration to get into the boot-mode with the boot0-Pin. And I explicit configure the read out protection (RDPto level 0.Also I can connect the device with the USB ...
STM32F412x - Stack overflow detection and prevention method
Hi,I'm using STM32F412 module with freeRTOS (CMSIS_V2) middleware in STCube IDE.Can I achieve below functionality as a stack overflow feature using STM32 MPU (Memory Protection Unit)?1. Detect corruption of a function return address before the functi...
Resolved! HAL of HRTIM Master timer
How to convert these LL to HAL? /* Clear ISR flag */ HRTIM1->sMasterRegs.MICR = HRTIM_MASTER_IT_MREP;and HRTIM1->sMasterRegs.MCMP1R = (MULTIPHASE_PERIOD / 5);If I use Timers A-EI usually use these:/* Clear Interrupt flag */ __HAL_HRTIM_TIMER_CLEAR...
Hi Team, we are using STM32F407 in our project, Could you please suggest OS for it. And our requirement is it should support USB stack and basic interfaces like I2C , SPI, PWM etc.
Can we use freeRTOS?Note:- But we can see freeRTOS does not have USB support.
How do I receive a char from the USB keyboard ?
I have a custom H743 board with HID (USB host enabled in the Cube) and a keyboard connected.the device has enumerated, I am getting 1300 SOF interrupts a second.but how to receive a char from a keypress ?Can someone ( using the cube) add the few ext...
LL_Init, LL_FLASH_SetLatency, LL_ADC_RESOLUTION_12B... What does "LL" mean ?
This is one question where Google is obviously not going to work... Can't seem to find out what "LL" means.Low Level maybe ? I see that LT means Lib Tool but no idea on this one.Thanks, boB
Resolved! STM32H743 variable not updating in interrupt handler
Hello,i have a strange situation happening and I really can't catch the reasons; in my project I set up an SPI transfer and set a global volatile variable that keeps trace of status state://Transmit Data if(spi == AMPLI_SPI4) SPI4_TransferState = TRA...
Writing a USB host for a Composite USB device. (Quectel BG96 modem)
I started off by using the STM cube generated libraries.Reviewing modem's documentation, i assumed that it will be just a CDC device with a few minor changes. I asked Quectel for device descriptor, they sent me one for EC21/EC25 which is similar to B...
FreeRTOS : Inerrupts
I work with FreeRTOS and I have two interrupts that can be triggered at the same time: An interrupt on a Timer in Input Capture mode (because I'm working with an ultrasound sensor HCSR04) and a UART interrupt (which is the reception of 'a character )...
