Resolved! HAL_UART_Transmit_DMA does not trigger HAL_UART_TxCpltCallback interrupt
Hi, I want to use UART with DMA on my STM32F407 MCU. I would expect that it would trigger `HAL_UART_TxCpltCallback` interrupt on transfer complete, but it does not do that. I tried many different configurations in STM32CubeMX:enabling "USART2 global ...
DFSDM sinc filter STM32H743 Problem
Hello,I am trying to use the DFSDM module on the Nucleo-H743ZI2 board .As a minimal example, i tried to use a sinc filter of 2. order with a FOSR of 4.Channel0 is activated in the parallel mode, standard data packing mode and the setting to take data...
[STM32] Why does the LCD current gradually increase and then decrease gradually?
I use STM32L496To save current to a minimum, It briefly enters NOMAL mode (0.2mA ~ 6.3mA) and updates the LCD numbers, then stays in STOP mode (0.2mA) for about 1 second and then wakes up with RTC.I keep repeating this.However, in STOP mode, it alway...
[RM0399/RM0433] Typo in SYSCFG register map (Multiple occurrence of SYSCFG_CCCR register)
Hi! Noticed a typo in the system configuration controller (SYSCFG) register map in both reference manuals RM0399 (Rev 4) and RM0433 (Rev 8). The SYSCFG_CCCR register is at two different offsets (0x28 and 0x2C) and SYSCFG_PWRCR is missing. I think, S...
Flash wait states meaning
Hi i have a generic doubt about falsh wait states:Say we configured the PLL to run system core clock at 160 M Hz, with flash wait states as 5.Then is cpu is equvilent to 32 MHZ core performance? (assuming 1 clk/ 1 inst, no ART's)Could some one help m...
STM32F469 - Execute code from QSPI Externa NOR Flash
I want to interface N25Q.. External NOR flash with STM32F469. Where I want to load and execute the code from N25Q External flash memory using QSPI memory mapped mode.Is this solution is Possible?If yes, from where I can get support?
SAI & I2S / DMA Callback imbalance - SAI Callbacks are called slightly more often than I2S Callbacks
Hello,I have a strange issue here trying to read 2x PDM mics from the SAI peripheral and output the audio over the I2S peripheral here on the H7.I use what appears to be the correct frequency for both peripherals and clear audio coming out, until the...
STM32F407VE sampling signal with ADC.
