Hello!I'm new to DMA concept, and need some clarification on several DMA questions (STM32h7). Q1. From RM0433: "To ensure data coherence, each group of transfers that form a burst are indivisible: AHB transfers are locked and the arbiter of the AHB b...
Hello folks, we are working on an application where STM32L072CZ needs to wake up from STOP mode on a data received interrupt on UART and LPUART RX lines. We are aiming for STM32L072CZ to be in low power mode and needs to wake up when an external sens...
Posted on February 07, 2013 at 19:23Hello, My intention is using TIM1 Complementary PWM Channel 1-3 for Brushless Motor Control. I want to sample the Phase Voltage at the middle of PWM ON Duty Cycle. I have configure TIM1 to output 6 Channel PWM but...
Hi,someone can explain me how to calculate the "dummy cycles" number reading an external flash qspi such as the Winbond W25Q64JV ?I have to read in qspi mode with the Fast Read Quad I/O (EBh) command in SDR mode. The flash memory datasheet asks for 4...
I am using the STM32G474 and have the following situation:I have configured a Timer to run continuously at 25 kHzThe Timer triggers the ADC to start a sequence of 6 conversions (i.e. 6 ADC channels)Upon completion of each ADC conversion, DMA transfer...
With SYSCLK set to 400MHz in MX Clock Configuration there is no problem, but any setting above ~420 up to the maximum of 480Mhz causes the system to 'crash' during initialisation in HAL_RCC_ClockConfig(..). More specifically when or after RCC->CFGR i...
Hello, I am currently using the STM32F407IE (Board A) and want to use another STM32 (Board B) with it, but I want to be able to program board A via board B using a SPI interface as I can use this as a general comms interface as well. I know you can p...
Hello everyone,I need to add the HTTP feature to my project. Since I have created my project under the "Package 1.17" for STM32F750N8Hx, I should use the last release of LWIP library in the mentioned package for my project...Here is what I am facing ...
The SPI2_MISO pin (PI2) at the arduino connector of the STM32H745XI board was accidentally connected to the MOSI of another SPI device giving around 5V and now the board red LED (LD3) keeps being on...According to the user manual, this means STLK Ove...
With STM32L562, I'm implementing a firmware update strategy using the double flash bank.I write the new firmware in the second bank, then toggle the FLASH_OPTR_SWAP_BANK option bit, and then trigger a reset with OBL_LAUNCH.To write to the second bank...
