Resolved! HAL_SAI_Transmit() does not stop the I2S clocks when complete
Hello,Some background:STM32CubeIDE 1.6.1MCU: STM32L4R9ZGJ6SDK: STM32Cube_FW_L4_V1.14.0 (Yes I know it's old ~ 2019) Project is too large to update at the moment.I am currently debugging external DAC audio issues. I reverted to using simple SAI blocki...
Hi, i use the stm32f405rgt6 and like to jump to the system memory 0x1fff0000. It never stays at DFU stm32_bootloader, it always starts application again.
I tryed two methodes, one just jumping to that address 0x1fff0000 via function pointer and second writing some magic numbers at 0x2001fffc and placing some asm code in the startup *.s file to jump branch to the system bootloader. I had to change cont...
Cube always generate RTC date/time reset at startup, for LL libs, STM32H73X, Cube version 6.3.0
For F73X, there is following code that avoid resetting date/time:if(LL_RTC_BAK_GetRegister(RTC, LL_RTC_BKP_DR0) != 0x32F2){.. LL_RTC_BAK_SetRegister(RTC,LL_RTC_BKP_DR0,0x32F2);}Shouldn't H7 behave similar to F7, regarding RTC initialization?
Resolved! STM32L052 - RTC with implausible or Zero - Content after RESET due to leaving the standby mode by recognizing of level LOW on RTC-TAMP1 (PC13)
The tamper contact RTC.TAMP1 on PC13 is used for entering and leaving the standby modus in tamper - level - detection - mode. The detection of low level on RTC-TAMP1 finishes the standby mode and restarts the controller. That is all OK. but in about ...
How to stop receive data in this code? or How to stop a get char? I used Interrupt to scan WiFi Information. I need only SSID. To input a buffer (Ring or FIFO) but it keeps bringing inform.
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { if(huart->Instance == USART2) { RX_Data[Rx_Index] = RXD; Rx_Index++; HAL_UART_Receive_IT(&UART2_WIFI,&RXD,1); } }
STM32L073 RTC/LCD clock frequency
The RTC/LCD clock can be derived from HSE (prescaled). In this case, the prescaler must be chosen appropriately so as to get an RTC/LCD frequency within the admissible range.Using CubeMX, when the limits are exceeded, the tooltip says:* (tooltip over...
Modifying ASC python script for Keyword spotting. getting error during log mel feature extraction. Please help
hi, am modifying the ASC python code for keyword spotting. Am using dataset which is 1 sec long wav files whereas ASC dataset is 30sec long wav files. while doing spectrogram-feature extraction am getting value 0.what is the frame length and hop leng...
Unable to get data in SRAM1 when DMA1 is configured for I2S2, in STM32H753xx
Hi STM community,I have created stm32 project in STMCubeIDE. I2S2 configured as Half duplex Master in receive mode, 16k audio frequency and 24 bit on 32 bit format. Able to receive data in polling mode.But not able to receive data in SRAM1 memory ...
Resolved! STM32F411CE DMA odd interaction with PWM timer
I am trying to use DMA to capture data in the background (from ADC) while I use PWM to control 2 motors. When I use DMA to capture the ADC values from my sensors it works fine. When I only use my PWM timers (without DMA in the background) the PWM wor...
