Hi Martin I use the lsm6dsv16bx. at the moment i am using this on an extrem small board with I2C on a QWII connector. Unfortunately I cannot work with an IRQ from the LSM. I can read the FIFO but I can't read it fast enough via the i2c bus and ESP32. I have also checked the pullup from STM32 and ESP...

Hi Martin With your help from last time it works to sample at 480Hz and write to disk in a separate task in the second core. Perfect! But there are a few errors in the data. I will call these needles. I have sampled the LSM6 in IRQ with the STM32 and there the values are perfect (but I can't save to...

Hi Ben Sampling data is simple: create an IRQ with the correct timer setup. Read data in the IRQ-macro and collect it in a large buffer. When the buffer is full, save to disk or send with USB/Bluetooth in one block to the App-Developer. And even a little better if there are two large buffers then yo...

Hi LeighM, Hi Martin

I have tested in software mode but it is much too slow for my application. I can write a wave file, but with a few kByte it takes minutes.
Would it be possible to have a component to use the SD disk in sd-mmc with 4bit like esp32?

I think that the card with this pin can only be used with SDMMC and not in the SPI bus. With the ESP32 there is this possibility. Could you do the same for the STM32? especially because the software mode is much slower than the SPI hardware as even worse in comparison with the SDMCC SPI is slower (~...

Hi LeighM, Hi Marti Yes it's working in software mode. With the SPI unfortunately not yet. The software mode is usually too slow. I will try it out. It would be an advantage if it works with the SPI Hardware. I will also try it with the hardware from the post, which I will also use https://www.flowc...

I tested with the osciloscope and

C-code is working to set the Pin to 1

Clock is working
CS is working
MOSI is alway 1
MISO is alway 1

I tried with the c-code, but it is still not working, so i add the display and the ret_byte is alway 255

here the right port

SDI=D2
SDO=C8
CLK=C12
CS=C11
DAT1=C9 (set to 1)
DAT2=C10 (set to 1)

In softwaremode I can set the pin but not the 2 unused pin to set to high

Hi Martin, Hi LeighM I can change the pin in the 32F469Discovery.fcdx and it's run it without errors But it's not working to write a file.... I have probably mixed up port and pin, this I want to test and correct that. As a sample, the working I2C pins: 2025-04-11_14-51-21.PNG One problem, however, ...
