Hi! I use embendded ADC1 channel 3 in STM32H743VIT6 for sampling data. Input in differential mode. For improve SNR i added capacitor 47pF parallel to diff input pins see fig1. Also this capacitor required by AN5354 This led to decrease noise floor l...
I'm using stm32 MCU to interface with mcp4821 D A C . The MCU's spi data size is set to 8 bit mode.The D A C has a 16 bit register and (Starting from 0) bit 12 to 15 are configuration bits and the remaining bits are data bits . My problem is ...how ...
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 mentions TS_CAL2 in section 14.9, however this value does not exists according to the datasheet DS12766 Rev2 section 3.14.1.
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...
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...
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...
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...
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...
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 ...
