Dear Team,
I am using Adafruit Feather M0 BLE which has Atmel SAMD21 Micro controller.
My target is to read 5K of bytes for every 10ms through SPI. I believe, which is not possible without DMA then,
i have checked the SPI DMA driver and could not find.
Do we have the SPI DMA driver for Atmel SAMd21 MCU or how i can proceed or get it SPI DMA drivers for Adafruit Feather M0 BLE board?
i understood, the SPI DMA driver whichever you provided is your own library i guess.
correct me if i am wrong.
My target, is to use own Arduino driver files for my project implementation.
Could you please suggest any other Arduino board which has more powerful MCU with Bluetooth?
hope you remember my load of system which is provided in first message.
I am a beginner of using Feather M0 Bluefruit LE. I would like to send the sensor data (the data rate may be more than 3000 Hz) via bluetooth with Bluefruit LE. But I failed because the BLE code may affect the sensor data transmission (from sensor to MPU with SPI/I2C). I can get the right data by serial port without bluetooth. However, after I added the BLE code reference the example "blueuart_datamode" the data collected are always same in mobile APP.

Do you know the reason of it? Please help me and thank you in advance. I will attach my code in the following attachment.
