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...
Hi, I am using a STM32U5G9VJT6Q and need the Altium symbol. Because it is a relatively large IC I would rather copy-paste the names and pin numbers pairs to avoid any errors (not out of laziness), but: - if I copy and paste the pin names (or any othe...
When I'm trying to read Unique device ID register on Nucleo-H563ZI, either by using HAL_GetUIDw0() or by doing uint32_t uid1 = *((uint32_t*)0x08FFF800); hard fault occurs.
I am using STM32H743VI LQFP 100 pin. There is no PC2 and no PC3 so I need to use PC2_C and PC3_C as SPI MISO and MOSI respectively. I heave read many forums on here claiming there was a bug in the silicon making PC3_C not suitable for SPI communicati...
Hi,I am looking for a STM32 micro that can control this DSI display (datasheet attached).But the display has 4-lanes DSI interface and cannot seem to find any STM32 with 4-lanes DSI. The microcontroller selector tool only has "MIPI-DSI" option withou...
Our board has an STM32L031 as a SPI master with two AD5271 Digital Pots (R24 and R25) as SPI slaves. After power-on both digital pots can be read (return default of 511). The first digital pot accessed can be given a new value and that new value re...
Hello,in the STM32F7 it is possible to enable instruction prefetch and in the same time disable ICache. Then I suppose that the prefetching does not put the prefetched instruction in cache. Is it correct?Thank you
Hi!I would like to know if there is a way to handle "automaticaly" a transmit then receive transfert using SPI and DMA ?I think using linked list should be possible, but i don't know how to configure that.. -Create a single linked list (only 1 GPDMA...
There have been several threads lately where the posters have seemed completely unaware of what a "solder bridge" is, and how to use it. Example: https://community.st.com/t5/stm32-mcus-products/uart-in-stm32-l432kc/m-p/689335/highlight/true#M253126 P...
Hello, I am a little advanced STM32 user, but I quite struggle with eMMC memory and STM32F7 (on custom board with STM32F756I and Samsung's 32GB eMMC KLMB2G2JENB-041 in the 8-bit MMC interface). Optionally I can solder STM32H753I which is pin-to-pin c...
How to perform SPI communication within a board (master and slave)We are trying to loop back SPI communication within the board, and perform transmission by the slave and reception by the master on one board.The master's SPI CLK is connected to the s...
