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 all, Please confirm fpscr is a special status register in STM32 L5 series controller?The IAR compiler is giving "Illegal register name" error, when I tried to execute the instuctions in c or cpp project using "asm volatile(mrs and msr instu...
I am trying to make a project to use spi with dma to transmit and receiveeverything seems fine in "HAL_SPI_TransmitReceive_DMA" and HAL_OK returns but the code in "HAL_SPI_TxRxCpltCallback" is not reached
Hello,I read the input data over SPI DMA, but when I added the AI part ICache and DCache are enabled.The problem is that when ICache and DCache are enabled, the SPI DMA is not working.How can I overcome this problem?
Hello I will use these crystals for STM32L4R9AII6HSE Crystal 16MHz ±10ppm 8pF 60 Ohms (with external capacitors of 6pf (assuming stray capacitance of 5pf) and ext resistor of 1.6KOhm)https://www.digikey.com/product-detail/en/jauch-quartz/Q-160-JXS22...
I'm using the FMC of the STM32H743 to drive a 16-bit 8080-bus LCD controller.I've tried using DMA, MDMA and a CPU-loop to transfer data to the 8080-bus, via the FMC.The transfer frequency does not depend on whether DMA, MDMA or CPU-loop is used. This...
hi,I'm new in ST. I'm trying to implement SPI communication between FPGA and STM32L051R8T6 (slave).I've initialized the spi bus in main (HAL_SPI_Init()), so that it is set to use (HAL_SPI_RxCpltCallback).and from main i called HAL_SPI_Receive_IT (to...
Posted on August 16, 2012 at 21:45I came across the following problem: I have a free-running timer, and a signal being input on its TIMx_CH1 pin. I want to capture timer value for two consecutive edges on that signal, so I set up the CC1 unit for ca...
I have configured LED and it blinks properly until timer interrupt occurs. While timer interrupt part is getting executed, LED stops toggling. Once the interrupt part is executed, it starts blinking again. I know this question maybe dumb to many but ...
Hi Team,I want configure STM32G071CBT6 as SPI slave device. Is there any existing linux kernel driver for STM32G071CBT6?Thanks,Arun
