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'm new to STM32. I made a custom board using STM32H7S3V8T6, but I think the HSE OSC configuration is failing. If I build main.c in (in Boot, not Appli), if (HAL_RCC_OscConfig(&RCC_OscInitStructure)!= HAL_OK) This part doesn't make HAL_OK, so this go...
Posted on April 14, 2018 at 23:13Hey everyone,My app based on STM32CubeF7 Firmware Package V1.11.0 / 23-February-2018 gets stuck in SDMMC_GetCmdResp1() during directory scan randomly - it can stuck just after switching on or after 2 minutes of worki...
Now I want to use ADC3 to collect the voltage of single-ended signals. I used IN1 channel to collect the reference voltage source of 1.5V and the internal channel to collect the internal reference voltage source of the chip respectively. The test res...
Hi,I'm trying to set my setup my SPI1 as slave full duplex on my STM32G030K8 and i reach the HAL_SPI_TxRxCpltCallback when receiving message, but I always read value 0 in my rxbuffer when my master is spamming 16 @ 1MHz at a 1 sec intervall. Also, my...
Hello! I am working with a STM32U073 on 1.8V and I want to use the USB feature. Indeed, the datasheet tells us that USB needs a separate power supply around 3V (4.1 Power supplies), but every time when I apply this voltage on VDDUSB pin, it goes to t...
Hi, i have configured BKIN pin to detect fault for my overcurrentSo for my motor driver if this pin sense BKIN input. How much time it be will taken by my microcontroller to sense and to act to shutdown my PWM gate signalsIs it hardware glued logic t...
Can Single DMA channel be used for multiple DMA Streams?As per Table 43. DMA1 request mapping in reference manual, Can I use Channel 6 for Stream0 (TIM5_CH3), Stream 3(TIM5_CH4), Stream 4 (TIM5_CH2).I understand that Single stream I cannot use more t...
hello alli am having stability issues with a sample code that uses ethernet with lwip and freertos.practically the operation is unstable, after a few resets it works but then hard faults appear:HardFault_Handler() at stm32h7xx_it.c:88 0x8000f88<signa...
Hello, I try to add MSC feature to my app. MCU is L452.To avoid side effects, I started a brand new app with cubeIDE/Mx.I activated USB_DEVICE feature.I declared the USB_DEVICE as mass storage class.I had a look to the MSC_standalone example from G0 ...
Hi there I am using STM32L051 to talk to a RS485 transceiver and I am having problem with the receive part.System is as follow: laptop->FTDI USB converter-> Renesas transceiver -> STM32I want to update the single byte buffer when a character is detec...
