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...
Hello,i have custom made board assembled by STM32F767BIT6 and external SDRAM IS42S16400 for video buffers.The MCU runs at maximum speed 216MHz. LTDC seems to work fine bud when i use dual layer, the second layer seems that reading from external SDRAM...
I am running USB in Mass Storage host mode. On connecting the device, USB FLASH stick, it takes around 20 seconds to change the Appli_Sate from APPLICATION_START to APPLICATION_READY in usb_host.c file. It is normal ? Can the time be reduced ? Than...
Hi I m using SPI to transmit and receive data from a sensor, the sensor return 3 bytes of data, SensorRXBuff[0], SensorRXBuff[1], and SensorRXBuff[2], i m gona use these 3 byte for indivual computation, i enclosed the function below, could anyone ad...
Hello folks,I've been having a weird issue and haven't found anyone else with the same problem, so I figured I'd post here.I have a project for the STM32H735 BLANK. The PCB has an 25 MHz external oscillator (ABM8W-25.0000MHZ-8-D1X-T3) used as the HSE...
I have a custom designed board using a single WS2812B RGB LED.I use the DMA to control, just as "all" examples and drivers use it.Fairly simple, and it works as a charm.99% of the time...Symptom:Once in while, it starts to show a wrong color.Fx. if I...
Hello. I have connected 32 strips of ws2812 connected separately to 32 gpio of stm32f407vgt6, each strip has 30 chips in series, how can I drive all of them? Dma, pwm, uart and spi modes doesn't support this number of strips separately.Thank you
Hello,I've been trying to find a solution on the forums for several hours now, to no avail!I have just put my programs on STM32F401, I compile with MBED Studio. I used to light my WS2812 LEDs with a KL25Z (NXP) always using Mbed Studio and my library...
Hello,I am using STM32H733 mounted on a custom PCB. The problem is that if I power the board on, the program inside the MCU does not start. The programming is done over the JTAG/SWD interface. After programming, the code is able to start running.Howe...
I developed a 62.5kbit synchronous self-clocked (similar to SDLC) communication firmware for STM32F412, to be interfaced with an old device via RS485.It works in "bitbanging" using a 16us interrupt timer (TIM11) to sample the bits and EXTI0 (PB0) int...
Hi everyone, I want to read ADC from DMA with injected conversion channels. In HAL library for STM32F407VG, there is no HAL_ADCEx_InjectedStart_DMA. This command gives invalid error. Anyone knows about this. Thanks.
