Hi,I have a well functioning application transmitting on uart4 using GPDMA1 CH1.If I turn on DCache, then it does transmit the correct length, only all characters are 0x00 (no problem in turning ICache on).In HAL_UART_Transmit_DMA(huart, (const uint8...
Hello,I try to use I2S in full duplex mode master with DMA but it doesn't work as expected.The I2S is configured in 24 bits @32Khz.DMA TX and RX are configured in half-word circular mode.I can send data manually but if I loop the input to the output ...
How to PWM input capture based on its frequency and duty cycle.
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...
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 ){//...
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...
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 ...
Hi, i want to know how much pwm signals we can generate from stm32go71 ic?
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...
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...
