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 everybody,for my current application I would like to disable the prefetching of the OCTOSPI peripheral.I'm using a STM32H723VGT6. Ideally one can configure it to be in memory mapped mode but still do every transmission without caching or prefet...
Hi there,I am trying to extend an SDRAM(W9825G6KH-6) for my homemade board with STH32H743IIT6.According to the SDRAM datasheet:I want to set the FMC clock to 130MHz with CL=2.So the MCU clock config is as follows:and according to the SDRAM datasheet:...
Hi everyone,We are trying to program the MCU flash memory to write and save some data on it.After successfully writing to a single sector, we can't delete the sector content anymore.We are using HAL_FLASHEx_Erase to delete the sector.In particular, w...
Hi,I use a STM32G030. The application works fine when we compile it with option -O0 (no optimize).It fails when we using the function HAL_ADCEx_Calibration_Start() for the calibration of the ADC.This function returns the fail at the follow location:T...
I have tried normal GPIO setting with pullup/down and setting AF5, but it just stays the same level, but its shape changes (see additional pictures).I have just connected the probes. (MISO is blue) // *** SPI *** // NSS (PB12) GPIO_InitStruc...
Hi to everybody.I'm struggling to figure out this issue: I got a "NMI_Handler" error...uint32_t *p = (uint32_t*)0x08080000UL; uint32_t val = *p; //here jump to NMI_HandlerIf I put the addr to 0x08070000UL (e.g.) no probelm.I'm using a STM32H562RGTX ...
I am using TIM1 for medium-frequency PWM and TIM8 for high speed ADC sampling with a STM32F765VIT6. TIM8 triggers ADC1, ADC2, and ADC3 where DMA streams collect the data. The frequency of TIM8 is a multiple of TIM1 so once it is started it will remai...
Hello,I have been struggling to make this post because I wanted to post a very clear question after I had found the source of the problem. However, I have been working on this problem nightly for two weeks now and even still I can't pinpoint precisel...
First time i set up SPI, not using HAL.In the debug, i see that not a single bit is set.What am i doing wrong? SPI_HandleTypeDef spiHandle; spiHandle.Instance = SPI2; // SPI_CR1_CPOL SET_BIT(spiHandle.Instance->CR1, SPI_BAUDRATEPRESCALER_256...
Posted on February 26, 2016 at 03:02The processor is an STM32F373VC using STM32CubeMX generated code with the FREERTOS option enabled. I have attempted to add the code: NVIC_PriorityGroupConfig( NVIC_PRIORITYGROUP_4 ); to the code in main.c as instr...
