Currently I am trying to replicate the RL78G13 set-up from the Analog Devices wikipage:
I have made all the necessary connections (assuming DGND connector to J18 pin 7 is a typo and that it should say J11), however, my RL78 is unable to properly communicate with my eval board.
I have supplied the VCC with 5V and the VDD and VCC with +/- 7.8 V respectively and given all three a single shared ground. I believe the problem to be communication between the boards, as when stepping through the code it appears that SPI_write and SPI_read in communication.c are where the issues lay.
Any help would be greatly appreciated.
