NUCLEO-F401RE UART not showing up on logic analyser via pins
I am using a Nucleo-F401RE and wanted to look at the UART section. Ideally i wanted to see the pins go up and down to see what they are doing. I am using huart1 so the transmit is on PA9 and receive is on PA10. I've hooked up the logic analyzer to PA...
Resolved! Where is the documentation for the CMSIS-DSP library
I got STM's libraries, grabbed the X-CUBE-DSPDEMO & AN4841 & AN4891 (section 3 on FFT demonstration) but haven't seen any documentation on the DSP library API. Have all the examples which are great, but still a good documentation for reference would ...
Resolved! STM32U5G9VJT6Q Schematic symbol not generating and PDF pin names not copyable
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...
Resolved! STM32H563 hard fault when trying to read UID
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.
Resolved! PC2_C PC3_C on STM32H743VI
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...
Resolved! Micro to control 4-lanes DSI display?
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...
Resolved! 'L031 SPI master with multiple AD5271 slaves
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...
Resolved! Instruction prefetch and cache in STM32F7
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
SPI with GPDMA
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...
