UART interrupt switch between USART_CR1_PEIE | USART_CR1_RXNEIE and USART_CR1_CMIE
Hi, just want to know if it is possible to switch the interrupt between Character match and Each character received interrupt on the fly without stopping the UART ?

Manual RM0454 Rev2 for STM32g0x0 inconsistent with datasheet DS12766 Rev2.
Manual RM0454 Rev2 for STM32g0x0 mentions TS_CAL2 in section 14.9, however this value does not exists according to the datasheet DS12766 Rev2 section 3.14.1.
software reset for STM32f302vb
i have flashed RTOS firmware at location 0x8000000. i have another firmware(led blink) at location 0x8001e00. i am unable to jump from 0x8001e00 to 0x8000000 location. but i am able to jump from 0x8000000 to 0x8001e00(led bllink) and it is working.pl...
Get corrupted Data from SPI when using DMA on STM32G071 Controller
I want to receive SPI Data from an external Chip (which is running my software too).So I configured my SPI2 into Slave Mode, Receive onlyThe first thing what I did (to check if everything is working fine): I used the RXNE Interrupt and copied the rec...
ADC - DMA transfer fills only half buffer Stm32f7
I'm using an adc channel of Stm32f767zi to get 1024 samples of an analog signal and transfer data directly in memory trough DMA. I configured ADC and DMA with cubeMx, and I start the conversions trough software, when it starts until the half DMA call...
read from UART DMA buffer on the fly
Hi, I have the below code where I trigger the UART DMA and write to a buffer, and in the while loop I simply do a read from the buffer 1st element:MX_UART7_Init(); Uartret = HAL_UART_Receive_DMA(&huart7, uartbuf, 300); while(1){ if(Uartr...
Hard Fault Detected STM32L031k6t6
Hey STM team, Recently I started to work with the STM microcontrollers. In my current project I have a STM32L031k6T6 with the ADC0 (PA0) reading the voltage and the channel 1(PA1) reading the Current. My Sample rate will be 1920Hz ( 32 points / cycle...
H745 DMA hardware problem?
I have encountered a strange problem with some of the dmas seeming to not be able to write to GPIOD ODR. I am using 5 dmas in a chain to write 16bit data to port D. Initially, i was using dma1 streams 0-4 but noticed that the signal was correct for ...
Waveform generation DAC DMA
I am trying to generate a trapezoidal waveform with slew rate 45V / us that is triggered every 50ms by an interruption generated by a timer. I am using the microcontroller stm32g474, which has 2 DAC with 15MPS. I am using DAC3 with DMA (circular mode...
