How to start with HSUART

[amolborase]

Dear All,

I am new to PN7462 and working on  PN7462 Development board. I want to implement HSUART protocol  independently for one  product. I also  refer  example PN7462AU_ex_phExHif  from SDK but I get confused that how can start from very basis steps like Setting Clock, GPIOs for HSUART and Initialization etc. I request you to please guide me and If any one have sample code than refer to me so I can get better idea about HSUART. Thanks to All in Advance.

Hello Kan_Li,

Sorry for late reply, I have checked the file that you indicated but  I didn't implemented HSUART still, Because currently I am doing project using PN7462 chip. I started to programming in PN7462 chip,create new fresh project and add files containing in PN7462AU_ex_phExRf project but I get an error like

 So, please guide me that how can I start with fresh project and which library files, I will have to add after creating fresh project so that I can implement UART and SPI interface.

I hope you will guide me, Thanks in Advance....

Hi Amol,

The clock settings can be found in phFlashBoot_HwSetup(), and GPIOs for HSUART and Initialization can be found in the source file of "phExHif_Hw.c":

Please refer to "14.3.3 High speed UART" in the attached UM for more details.

Hope that helps,

Have a great day,
Kan
