Linearity of HRTim Compare
Hello together,when inspecting the behaviour of the HRTimer regarding the compare output, I found that with Clk multiplier 32, there is a non-linearity in the compare timing (stepwidth) of about +150 ps (330 ps step instead of 180 ps between adjacent...
Resolved! High speed data transfer to a memory mapped peripheral possible using FMC fed by DMA?
Is it possible to burst transfer a block of data from STM32 internal Flash/SRAM to an external memory mapped peripheral device with an SRAM style interface i.e. Address, Data, CS and R/W using the FMC fed via DMA?
Resolved! Connecting LSE to STM32L010?
Hello, all, and Happy New Year!I'm trying to design my first microprocessor board. I'm trying to follow the guide given by Phil's Lab on YouTube, at https://youtu.be/nkHFoxe0mrU?si=Dx6cx6-a9yXncmEW, which I find very helpful. I'm using an STM32L010K4...
Resolved! W25N01xxxIG Driver for STM32H7
Hello, I have been trying to make a driver for the Winbond(W25N01GV) NAND flash over QSPI(to use it in memory-mapped mode) but I've been failing so far. Can somebody give me some ideas about what I am doing wrong? I used W25Q256 before, but now I wa...
Resolved! Device for testing car headlights
Hello . I need to make a device for testing car headlights. I'm going to turn them on and check if all the lights are working. new models of car headlights work via can bus and lin. what stm32 will I need and what components. the device is supposed t...
Use W25N01GVZEIG for octaspi and Touchgfx for external loader
Hello, I want to use W25N01GVZEIG as an external loader to use it for Touch GFX and stm32h723zgt6. I used to use w25q256 before.thank you
need to read BOOT0 pin on STM32H725
I have designed a set of boards for a client with one USB interface to the main controller. We can bootload it by the usual methods, and bootload the CPUs on the other boards by pass-thru from the main controller. I send coded messages to the main ...
STM32U545RE SPI1 issue
HelloI am using STM32U545RE (LQFP64 package) for my project as master controller. I have interfaced a slave ADC to the uC using SPI1 port. From datasheet, SPI1_SCK can be either :PA1, PA5 or PB3.While configuring PA1 as SPI1_SCK it was observed that...
STM32U545RE USART3 issue
HelloI am using STM32U545RE (LQFP64 package) for my project as master controller. I am using the following pins for USART3 along with a transceiver chip ADM3061E and an additional GPIO output configured to act as the Enable.USART3_RX:PC5USART3_TX:PC4...
