Hi,I have had partial success implementing DMA with I2C as below but the only way I can receive the data "val" is by adding a HAL_Delay of 1uS and the "val" is shown as an incorrect value. Is there anyway to both do the DMA send and receive without t...
I have a project that is using DMA channels to transfer ADC values to DTCM. The values seem to be getting to the memory correctly but I was confused by Figure 1 of the datasheet which shows the ADC/DMA/SRAM on the AHB but the DTCM on a bus that appea...
could someone explain how this chip works this function table is so confusing to me
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...
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?
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...
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...
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...
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
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 ...
