是否可以从单芯片同时使用全部4个SPI和6个UART

我似乎记得上次我们使用PIC32 MX795…我看了这个，你不能，因为一些SPI和USAT外设共享相同的PIN。MPLA.X中的和声配置器是一个有用的工具，可以从外围设备中获得最大的使用量，即使你计划不建立一个和谐的项目，也值得建立一个小的虚拟项目。只是用这个。

    I seem to remember the last time we used a PIC32MX795... I looked at this and you can't because some of the SPI and USART peripherals share the same pins.
The Harmony Configurator in MPLAB.X is a useful tool for getting the most usage out of peripherals, even if you are planning not to build a Harmony project, it's worth setting up a little dummy project just to use this.

您好，我知道和谐设计，但我有关于SPI和UARTIFI的困惑，我需要使用所有4个SPI模块，我可以很容易地配置在和谐设计，但混淆是，如果我想使用所有4 SPI和6 UART单一硬件如何配置它？谢尔斯诺姆

    Hello
     yes i know harmony design but i have confusion regarding SPI and UART 
if i need using all 4 SPI modules i can easily configure in harmony design
but confusion is if i want use all 4 SPI and also 6 UART single hardware how to configure it?
 
 
Thanks

不，不可能同时使用6个UART和4个SPI外设。对于引脚39，AC1TX/SCK4/U5TX/U2RTS/RF13不可能同时使用UTAR5，或者UART2与硬件握手。在PIC32 MX795设备中，以及在MX5XX、MX6XX和MX7XX系列中的其他设备，大多数UAR。T、SPI和I2C外围设备以1个UART和4个引脚组成，1个UART具有2个引脚，1个SPI和1个I2C外围设备，它们共享相同的4个I/O引脚。在这样一组外围设备中，如果引脚不共享，则只能同时使用2个外围设备。这些外围设备组和1个独立的SPI，所以如果您使用6个UART外围设备，只有1个SPI外围设备可用。迈西尔

No, it is not possible to use 6 UART and 4 SPI peripherals at the same time.
 
For pin 39, AC1TX/SCK4/U5TX/U2RTS/RF13 it will not be possible to use SPI4 at the same time as UART5, or UART2 with hardware handshake.
 
In the PIC32MX795 device, and other devices in MX5xx, MX6xx and MX7xx family,
most of UART, SPI and I2C peripherals are organised in groups of:
1 UART with 4 pins, 1 UART with 2 pins, 1 SPI and 1 I2C peripheral, all sharing the same 4 I/O pins.
In such a group of peripherals, you will only be able to use 2 peripherals at the same time, if the pins are not shared.
 
I think there are 3 such groups of these peripherals, and 1 independent SPI,
so if you use 6 UART peripherals, there is only 1 SPI  peripheral available.

要看引脚上是不是冲突的，要是不冲突是可以用的
