Hi Martin, Hi Ben Yes I have a second program to write two buffer (array) of 12000 integer to wave file. Its working The problem is in the csv Version to write csv file. It's very easy to sample and save if I reduce the samplerate. but if this different time would be less, the csv version would just...

Hi Martin Thank you for your support I attached 1 ws2812 - and can confirm that there us an issue... Move WS2812::Initialise to a macro and it stops working - which is very odd. Not at all sure why it wouldn't work from a macro (as main is just a macro too!) it is not so nice but i can work this way...

Hi Ben Here a program to test the SD-Card: Press a key to start (GPIO19 on my board) The program write 10'000 line in a .csv file Its write a string of 128Byte for each line (21 times a fix number 10000,) If writing is finish it's write the time in line 10'001 in mSec and it send the time to USB 202...

Hi Martin My program works again! I can set the LSM6 with I2C master and I can read LSM6 with I2C master I had to set all I2C components to ch2! With almost the same program on I2C ch1 it works fine... Thank you very much for your support Martin. for the RGB Led I wrote a new post: https://flowcode....

Hi Ben I will prepare a program to post. I always append a string with length 147Byte and that works perfectly. Hour-long recordings succeed. Writing (append) a string 147Byte without changing sector or cluster takes only 54uSec (2.7Mbyte per Second?) Writing with changing sector or cluster takes 3....

Hi Martin I looked at the writing on the disk again and noticed something even worse. I always write the same amount of bytes to the disk. Once it takes 54uSec then after 2-3 times it takes 1.12mSec and then also once 3.25mSec. So 60 times longer. This always happens at regular intervals. These 3.25...

Hi to All The LED is working nice and it's comfotable to use. There is a little problem in a program with WS2812 I have made a test with WS2812 1.This LED can only be initialized in the main, it is not possible in the macro. The LED maybe give some problems with the power management and maybe also w...

Hi Martin

That make it even stranger

Yes, that too: In an almost identical program this works perfectly. I can also write to both IMUs.

Hi Martin

Yes deep sleep save power.
On my complet board:
deep sleep =0.7mA
light sleep = 2.0mA

Hi Martin

Your program works fine even if I add some more commands My program give a watchdog error if I write to I2C even in at loop an begin
