Resolved! QSPI STM32F767xx reads wrong data
Using STM32F767xx as QSPI master and Cortex M33 as a slave While reading the header (4 bytes) i see the first 2 bytes are correct always and the last 2 bytes as 0xFF's. If i take a capture directly from the QSPI pins on the slave i see correct values...
Resolved! STM32F334 onewire master onewire slave application example on stm32f3 discovery kit
I am very new to STM32 dev environment using atollic truestudio at this moment. I have very tight deadline of my project and want an example to see onewire master-slave transmission over uart/usart with or without dma. I tried to search it over the s...
STM32F334 TrueStudio - Adding libarm_cortexM4lf_math.a Getting error: arm-atollic-eabi/bin/ld.exe: <WWDG_EXAMPLE>.elf section `.rodata' will not fit in region `FLASH' and region `FLASH' overflowed by 101180 byte
The size looks like around 107KB of libarm_cortexM4lf_math.a library, the total flash is 64KB in STM32F334x SoC. Could you let me know if I want to perform FFT (Fast Fourier Transformation), is there any alternative or light weight library I can use....
STM32H7xx - Bug in SPI Driver HAL in larger transmission (32 bytes transmission in one call)
Hi all. I am having an issue with HAL_SPI_TransmitReceive routine under STM32H743. I am using STM32CubeIDE ver 1.10.1. In our setup for STM32H743, it is bare metal (no RTOS). The SPI is in Slave mode. In particular, I am using SPI4 as follows:Mode: S...

Hello,i found an error in the Datasheet DS12712 Rev 4 of the STM32G473 Controller.Can someone clarify please what will be correct:In Chapter 4.11 - "Alternate functions" it tells, that PA10 has an alternate funktion AF2 for I2C3_SCLBut in Chapter 4.1...
STM32L4A6ZG boundary scan has stuck inputs every 24 cells
Our design has a STM32L4A6ZG, we are using our own boundary scan tool to test the PCB. During testing we found that input of PF1 (cell 375) and PD13 (cell 207) where always high after some more investigation it looks like the inputs that are 24 cell...
Initialize SDRAM in SystemInit
Hello,I am using a STM32H7A3 and a SDRAM MT48LC8M16A2P.In a project using the emWin graphic library, I would want to store the relative buffer 'aMemory' in SDRAM.By reading on community and seeing the examples I understood that I have to write a Syst...
