spi.write() Implementation

Hi! I am having issues programming a LPC1768 to interface with an AD5791. I believe the issue is with spi.write(). Does anyone know where I can look at the source code for spi.write()?

Thank you in advance! Natasha

Hi Tash Woords,

Here are mbed sources on github (mbed HAL, just go down the tree to get to your target's SPI implementation) https://github.com/mbedmicro/mbed/tree/master/libraries/mbed/targets/hal

You can also do it in the online compiler, add mbed-src "library". Modify, test and see if it works or not.

Hi Martin, Thank you for the quick response! I tried looking through the sources on github and did not have much luck. However, I am new to this field - so it is probably there. Do you have any tips on finding it? I thought it would be in this file: https://github.com/mbedmicro/mbed/blob/master/libraries/mbed/targets/hal/TARGET_NXP/TARGET_LPC176X/spi_api.c

but did not see the actual implementation of spi.write().

Thank you again! Natasha
