Resolved! STM32L011F4U6 can't enter bootloader
I connect the PB9-BOOT0 to VDD, then power up the board, but it just run from flash(application program), not the bootloader, what's the matter? I am not firmilar with ISP, I suppose it should enter bootloader, and wait for ISP program to communicate...
Resolved! UART DMA error - What is the proper way to restart the DMA?
Hi,I am injecting a UART DMA error by using DTCM memory and DMA2. For example:// Induce a DMA error by using DTCM RAM for DMA2 which is inaccessibleif ( HAL_UART_Transmit_DMA( huart, transmit_buffer_dtcm_memory, num_bytes_to_transmit ) != HAL_OK ){//...
hal_delay() not working
So I've created a project and am trying to use the HAL_delay(10); but it gets stuck at this function when im trying to debug. I have been changing the clock and enabling the TIM2 so I don't know if i've messed something up. Here are the settings that...
Resolved! Solution for receiving BT audio and playing stored audio samples
I am looking for ST products that will:Receive bluetooth audio (i.e. from a smart phone)Play the bluetooth audio through a single minature speaker (mono)Play stored samples of a voice counting down numbers at intervals based on an external event (if ...
Generate Pwm Pulse
Hi, i want to know how much pwm signals we can generate from stm32go71 ic?
Resolved! STM32L4P5xx system bootloader: is RAM3 valid SRAM for the stack pointer?
Does the system memory bootloader for the STM32L4P5xx consider RAM3 as valid SRAM for the stack pointer?After programming bank 2, and then setting BFB2, The device will not boot into bank 2. The linker has the top of the stack at RAM3. The value wr...
STM32F205RBT7: Suggestions needed for reliable IWDG behavior
Hello ST Community,I’m working on a project using the STM32F205RBT7 and planning to integrate the Independent Watchdog (IWDG) for system recovery. However, I’ve encountered significant timing inconsistencies across multiple boards (tested on at least...
Resolved! STM32L4S5 write data to 2MB flash memory (STM32CubeIDE)
I am trying to write to the flash memory of the STM32L4S5QIIX microcontroller on the EVAL-ADIN1110EBZ development board. I have also tried similar code on an STM32L4S5VITX microcontroller on a custom circuit board.Short example code:uint32_t flash_me...
I2C_frequency configuration
Hi,I would like to configure the I2C frequency based on the input clock frequency. Is there a specific formula to calculate the I2C timing values? Also, I would like to know whether this formula is applicable to all STM32 microcontrollers, or if it v...
