Raspberry pi pico - record to sd card: error #33

Closed Hubert662 closed 1 month ago

Hubert662 commented 1 month ago

Hello, First of all, thank you for your post. Great job. I have a raspberry pi pico and I want to record audio to an SD card. I used your "record_mic_to_sdcard_non_blocking.py" file, and didin't change anything. I copied the "sdcard.py" file to the pico, and again didin't change anything. I have a microphone INMP441 and micro SD card module like this: MicroSD-Card-adapter

But something is wrong, and this happend: screen Micropython firmware: v1.23.0 (latest) What could be wrong? What am I doing wrong? I'm a beginner so maybe I made some simple mistake.

Sorry for the delay to respond. Do you still have a problem? If so, please provide the entire micropython code listing. It is difficult to help debug the problem with only a few lines of code. Thanks!

Thanks for your reply. I solved this problem. I changed "SPI bus speed to SD card" to 20.000.000. Now it works but I have different problem after closing file. I will write about it on the second issue comment.
