PIC18F47K40 EUSART1设置/初始化不成功

嗨，大家，我们从PIC18F46K22交换到PIC18F47 K40，给我们更多的代码区域。我们使用EUARTAR1在115200波特，驱动LCD显示器在PIC18F46K22系统上运行良好。虽然我们已经尝试了各种组合和建议，从各种结果Google问题，我们没有成功使EUSATAR1以任何波特率运行。我们已经尝试了MCC生成一个基本系统与EUSATAR1配置，但仍然没有成功。（但我们中没有一个与C）很熟。系统频率是64 MHz，但是数据表在这个频率上没有显示115200的波特率值，115200的最大值似乎是32兆赫，我怀疑这只是一个数据表遗漏，我们已经尝试过各种较慢的波特率。哦，看看我们能不能…但是没有。有没有人有一些汇编代码来初始化这个芯片上的EuSART1，这已经在一个真实的设备上被证明了？我相信它会去一些简单的东西，那就是丢失或不正确…但是什么/哪里等？如有任何帮助，我们将不胜感激。

    Hi all, we have swapped out from a PIC18F46K22 to a PIC18F47K40 to give us more code area.
We use EUSART1 at 115,200 baud to drive an LCD display which works fine on the PIC18F46K22 based systems.
Although we have tried all sorts of combinations and suggestions from various results from Googling the issue, we have had no success in getting EUSART1 to operate at any baud rate.
We have tried the MCC to generate a basic system with the EUSART1 configuration, but still without success. (But non of us are conversant with ‘C’).
The system frequency is 64MHz but the data sheet does not show an example baud rate value for 115,200 at this frequency, the max for 115,200 seems to be 32MHz, I suspect this is just a data sheet omission, we have tried at various slower baud rates just to see if we could anything ... but nothing.
Is there anybody out there that has some ASSEMBLY code for initialising the EUSART1 on this chip that has been proven on a real device ?
I’m convinced it’s going to de something simple that’s missing or incorrect .... but what/where etc. ?
It would be much appreciated for any help available.
Regards
Roy
