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...
Posted on July 08, 2016 at 16:09I'm trying to get the SDIO system working with DMA. The system works in the configuration without DMA.Now I set the read and write operations in the ''sd_diskio.c'' to DMA, by adding _DMA to the starting commands BSP_...
I've drawn my own schematic that uses the STM32F107RBT6 and LAN8720A chip.And this is not an work on company, not related with my job. just hobby.I made this to study firmware development in order to make toys that utilize Ethernet.and I ordered samp...
Hello everyoneI make SPI communication between Stm32f411 and module NRF24l01.I have written a function to transfer data from stm32 to Nrf24l01, and read data from Nrf24l01.Everyone help me to edit code because this is my first time using this protoc...
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 ...
Hello everyone, I am using the STM32F042K6 for a small project where I don't have much space. Therefore, I rely on the small package and the "crystal-less USB" function. The hardware arrived today, but unfortunately, I had to realize that the USB li...
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)(...
