STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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 ...
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...
I've been trying to set up MCU (STM32 L432KC) as an I2C slave device. I have previously tested it as a master device to interface with a port expander(MCP2307) and it works perfectly fine.The following is the code I am running. The master sends 1,2,3...
I'm using STM32F031K6 in my design. I want to store 16-bits variable (Timer's AutoReload Register) in a non-volatile memory. What is best solution for this application? Internal Flash or external 128b EEPROM ?Any STM32 example code available to store...
Hi,I'm trying to protect my code from being able to read by others.So I chose readout protection level-1,I could make it read protected and I'm not able disable it by using readout protection level-0,I have to disable it using ST link utility.But I w...
