I found the component and I copie the component

I working now

it looks like this will soon working fine.
I just suspect I need a component Notify ?

Hi Martin

'semaphore' or 'signal' or 'Flag' i have already tried, it works, but the watchdog is causing problems.
sometimes I don't need a delay sometimes I need 10mSec delay.
is there any other way than using a delay'? for example a watchdog reset?
or a setting that only triggers after seconds?

Hi Martin Fifo with the LSM6dsv16bx and LSM6DS3 are different. I had to read out the FIFO for a project and it worked. But a lot of effort. I can also post this once, it's about the quaternions. Now I have to read two LSM6dsv16 Accelero and Gyro data. That actually already works. But there are these...

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...
