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...
Is there a step-by-step example anywhere, known to work? I have followed numerous examples from several forums, but still no luck. The ADC value I get from the internal temperature sensor is always around 880. This equates to around 1 degree celcius ...
Hello,I am having problems with SPI connectivity. My problem seems to be the chip select pin that is controlled using GPIO HAL libraries. Chip select is pulled low for way longer than it is supposed to and therefore I cannot read the sent data proper...
Really new to programming these boards, and part of my project is to turn on/off these DC fans . I don't want to add any hardware to incorporate a switch, and was wondering if there was a way to program one of the power pins to be enabled or disabled...
I have used DSP in STM32F411 successfully,but when i want to use DSP in STM32G070 , i find the DSP files are some different,such as G070's DSP files : ./Sourse/. have a Cmakelists.txt. i dont know how to use that txt file, so i just add DSP as usual...
Hello,I am trying to get the CAN Bus on a Nucleo F446RE to receive messages from an ECU, but it will not. The STM32 has been tested in loopback mode and is able to trigger the interrupt and process the data upon receiving the message, and the STM32 i...
Hello,In my project I need to get very low power usage device. It works with camera, so when I am taking picture I need maximum processor speed since I need to be at least 4x so DCMI could support full speed parallel data.When I am done with my calcu...
I'm trying to transmit CAN messages with the stm32f4 from CAN2 to CAN1 (using a transceiver and so on). I'm trying to put the baud rate at arround 1khz so I can watch it using my arduino as an oscilloscope (which is able of performing 3666 samples pe...
The chip is STM32G491. The NRST pin is suspended. The option byte is default value.I find my board doesn't work after power up, so I measure the waveform of VDD and NRST as figure 1 below.Figure 1The green wave is NRST and the yellow wave is VDD. The...
I'm trying to generate periodic interrupts with an LPTIM on an STM32H723. I'm using HAL_LPTIM_Counter_Start_IT() from the STM32H7xx_HAL_Driver. My interrupt handler is never being called. I've confirmed that my interrupt handler is in the vector tabl...
I am sending an audio stream from memory to SAI2 on an STM32L476JG. There will be moments where I disable the DMA based on external asynchronous events. Can someone tell me the appropriate way to then reset the DMA so that when it begins again it i...
