i am able to use nrf24l01 to communicate raspberry pi with arduino, but the problem is the timing. I found it takes > 20 ms to send a very simple string ... (more)
I was pointed to st7565LCD.c for this question before, but SDK 13 does not seem to have that example. It would be really helpful if I can get spi_read() and spi_write() functions as welll. thanks.
Am beginner of nRF51822, please suggest programming tool and tutorial links.
Dear Nordic Team,
Thanks for supporting.
I have a nRF51822 Board (PCA10028) and Also i have arduino code for reabear from (https://github.com/RedBearLab/nRF5182... )this link. It was generated hex file also.
I am try to burn this ... (more)
