Rev 19 Page 16/59:I believe this should read "increase" instead. The purpose of Rext is to limit the current and thus lower power dissipation in the crystal. So, lowering Rext increases power dissipation. A separate issue is that this phrase is awkwa...
Below is the analog waveform for the SPI clock at 12MHz. How to improve the strength of this signal and get p-p 3.3V SPI clock at 12MHz ?"GPIO SPEED" set to the "VERY HIGH" setting. Apart from this, is there any additional settings required ?
I'm having an issue with initialising my watchdog, when I include the call to HAL_WWDG_INIT(&hwwdg2) in my code, it is causing any debug attempt to run into the hardfault handler due to some values in SystemClock_Config() being set to 0: __weak HAL_S...
Hi there! Are there any plans to add a hardware math accelerator in addition to the cordic and fmac that supports FFT's and other matrix operations entirely in hardware and runs in parallel to the CPU and communicates via DMA? A good example of this ...
Hi, i have stm32f0c8t6 micro controller. i am using adc-dma with timer interrupt. ADC after working correctly for a while, buffer values doesn't change. what could be the problem?
I am using STM32CubeH7 from GitHub (the latest commit is here). In stm32h7xx_hal_nand.c, I found something starting at Line 582: if (((hnand->Config.BlockSize) * (hnand->Config.BlockNbr)) <= 65535U) { *(__IO uint8_t *)((uint32_t)(...
Hi all,I am working on Nucleo-G474RE board to get the ADC result in multimode-continuous conversion- -dual regular simultaneous (ADC1-two channels (1,2) & ADC2-two channels (3,4)) with DMA transfer (peripheral to memory). Here I checked the buffer v...
Hi I designed a replacement pcb for a keyboard of mine with an STM32F401(RCT6).I used the QMK framework to make a firmware which I can download via DFU perfectly fine (I also uploaded it and checked it against what I downloaded..). The PC detects the...
I know there are hundreds of posts about this and I've been through most of them but still can't get things to work.The concept is simple: set up 2 Nucleo F446 boards, one as full duplex slave the other as full duplex slave.Master pseudo code:while 1...
Hello everyone! I have a STM32H750VBT6 controller with external W25Q128 QSPI memory.The bootloader starts from address 0x080000000, initializes the flash in memory mapping mode and starts the main program from 0x900000000.There was a need to update t...
