hello every one. im running something that needs high clock speed. actually i want to create picture with some moving LEDs. i have 75MHz on gpio but its not enough. i just know its possible. im using register codes. im using boolean array for image d...
__WFI(): (Wake up by Interrupt):leads to a one wake up as expected but swallows some interrupts if more interrupt sources are simultaneously produce interrupts. The understanding of this behavior costed me a lot of time. __WFE(): (Wake up by ...
Clarification: Can I be sure that the case in Errata sheet ES0491 "Device may remain stuck in LPTIM interrupt when entering Stop mode" never occurs for certain LPTIMx if no interrupts within it are used to wake up MCU from Stop mode and disabling of ...
I'm quite confused. The RM0440 states: "Note that read-while-write capability (or RWW) is only supported when the dual-bank architecture is active. This enables programming or erasing one bank while executing code from the other bank." Okay, for me, ...
It is the problem about the dma driver of stm32L452's sdmmc1.ide: cubeideboard: NUCLEO-L452REconfig: sdmmc1 with dma , sd 4bit, without rtossdmmc1 dma config : 1. {sdmmc1 both(rx and tx) : dma2_channel_4} or 2. {(sdmmc1_rx : dma2_channel_4) and (s...
Has anyone tried it and knows that it works/doesn't work?I can guarantee that a DMA request will not occur during the update of these registers.This would be on an STM32G474. I don't have my board as yet, so, can't try it.
The FRAM chip I'm using is cypress.For details, here's a screenshot of my chat with Cypress.Thank you very much.
I am currently experimenting with programming flash memory. I want to figure out how many sectors to erase before writing data into memory. I came across the following snippet uint32_t Flash_Write_Data (uint32_t StartSectorAddress, uint32_t *Data, ui...
I was going through embedded flash programming documentation of STM32F7 . I came across a term called "data read width". can some one explain this term ?Flash memory single bank organization (256 bits read width)Flash memory dual bank organization (1...
For a long time I have been trying to guess how debug components are connected to the Cortex-M7 core in STM32F7 series of microcontrollers. It is supposed to be shown in e.g. the document RM0410 in Figure 587. This figure seems to be a copy of the sa...
