Hi, @junhuanchen 經過一些嘗試後,終於找到一個很快速的修正輸出pwm頻率的方式。 測試程式碼請參考附件的pwm_demo.txt檔案。 [pwm_demo.txt](https://github.com/sipeed/MaixPy3/files/7942492/pwm_demo.txt) 輸出波形圖請參考附件的圖檔。波形圖檔有點跑掉,請包涵。 ![pwm](https://user-images.githubusercontent.com/32902617/151181436-0f479dbc-a95e-4d82-9d51-cd77c3b7ff53.jpg) 要達到輸出想要的pwm頻率,可以從PCR的16bit counter回推。 假設PWM頻率為100,16bit counter設定為60000,100 * 60000 = 6000000, 6MHz。 亦即從PCCR決定clock source,之後使用PCCR及PCR推敲合適的除頻係數。 從pwm-sunxi-group.c驅動程式來看,似乎PCCR及PCR的設定跟實際輸出有落差。 可以多試幾種組合,看看實際輸出跟預期的差別。 BR, Akio

關於獲取coco2017的txt可以參考yolo-fastest/scripts中的get_coco2017.sh的label檔案。或者是使用這個專案的script來轉換。https://github.com/ultralytics/JSON2YOLO 不過請問有人知道coco2017的類別是80類還是91類? BR, Akio

Hello Moritz, Thank you very much. Right now, we are trying to find a way to accelerate the SNN simulation approach by using brian2. I'll wait this project and trace...

Hello Moritz, after some trace about the brian2/device structure, is it the new brian2cuda is merged into brian2 in device directory, like cpp_standalone device, as a new cuda_standalone device? Best...
