Resolved! Incorrect 16-Bit HAL SPI Result in Loop/Reset
Using the stm32h745I-disco board and there seems to be an issue using HAL_SPI_Transmit in a loop. I get the correct SPI data for the initial transmission, but after that the 16-bit value is all over the place. Only 0xFFFF remains the same over the lo...
SPI2 not working on NUCLEO-L452RE
HelloI've got an issue to send byte though SPI2 on the STM32L452.SPI1 and SPI3 works without any issue. But nothing on the SPI2.The code was generated from STM32CubeMX.Here is the SPI2 init :static void MX_SPI2_Init(void) { /* USER CODE BEGIN SP...
spi1 bus with multiple slave is possible?
Mostly our spi will use these 3 signals (SCK, MISO, NSS (CS) ) in master rx only mode. where multiple slave are connected to SPI and each will have a dedicated CS in star topology as shown above. How to select this NSS/CS pin for individual slave, ca...
SPI4 Issue -> clock signal is generated but MOSI doesn't output any data
We are using the STM32H725IGT6 MCU. We are using 4 SPIs -> SPI1, SPI3, SPI4 and SPI6. We are able to communicate with the SPI slave on the SPI1, SPI3 and not able to with SPI4 and SPI6. We are able to see the SPI4 clock on the SCK pin, but there is n...
Resolved! Where to find systick register documentation for STM32F4 and H7.
Hi,I founded informations about the HAL systick functions, but I found nothing about systick registers in the ref manual of STM32F429/439 and STM32H745/755.For Cortex M3 STM32F10xxx/20xxx/21xxx/L1xxxx, I founded informations in the PM0056 Programming...
stm32f303re to write data in the st M95160w EEPROM and reading back the written data. but cannot write accurately. how to do that?
using stm32f303re to write data in the st M95160w EEPROM and reading back the written data. the problem is i am not getting back the accurate output. the output should be like this:status 0x0211 22 33status 0x00but gettingstatus 0x0200 ff ffstatus 0x...
16GB eMMC (8-bit) on STM32F676ZI
Hi, I connected a 16GB Sandisk eMMC in 8-bit mode to an STM32F676ZI SDMMC interface.I use HAL drivers and TrueStudio for development.HAL_MMC_GetCardInfo returns this information:CardType : 0 Class : 2293 RelCardAdd : 0 BlockNbr : 2097152...
Resolved! Low Level API function to register map for STM32G4 family
Hi there,in the ADC FIrmware driver API Description for the STM32G0 family a table exists that shows which LL function accesses what register. In the UM2570 (which is the same doc but for STM32G4) this table is missing. This is giving me a hard time ...
SPI using Registers in STM32H7 - There is no SPI1->DR (like in STM32F4)- only
I tried to follow the SPI transmit using Registers https://controllerstech.com/spi-using-registers-in-stm32/look like in STM32H7 , it is changed significantly for example SPI1->SR => SPI2S_SR.TXPSPI2S_SR. EOT EOT: end of transferTXP: Tx-packet space...
