Hi @artemopolus, NuttX already have SPI driver implemented and supply some macros to let you to communicate with your sensor. So, you just need to create a driver to communicate with your sensor and export it as a special device file inside /dev, similar to what Linux does. Please take a look at nuttx/drivers/sensors/ there you will find many examples. These drivers need to be initialized in the board code to be associated to an specific SPIn and its CS pin needs to be configured to be asserted correctly. There are some examples at boards/arm/stm32/stm32f103-minimum/src/ and many other boards. This is very easy to do, but could be a little bit confusing initially for people coming from baremetal or from RTOS that are very baremetal-like. For people with experience developing Linux kernel driver it is very straightforward. BTW, I think you don't need to open an issue here, it is better to ask these questions at NuttX mailing list, you can subscribed to it from here: http://nuttx.incubator.apache.org/community/ ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
