代码兼容性PIC12F1571和PIC16F15323

你好，我正在和一个在PIC12F1571.周围开发板的客户一起工作。现在，他们想通过添加一个UART来增加更多的功能。因为所有的引脚都在使用，所以不可能仅仅改变到PIC12F1572。相反，我们正在寻找一个代码兼容的PIC，但更多的引脚。在Microchip网站上的产品矩阵中，PIC16F15323是第一个出现14个引脚和1个UART的。如在数据表上看到的，前8个引脚与PIC12F1571A完全相同；在底部，它们添加了POTCC引脚，可以与UART映射。我的问题是：代码在两个之间兼容吗？这只是一个改变目标微代码和代码工作或没有工作的问题？我看到，例如，在PIC12上的RA4引脚是ADC的AN3通道，但是在PIC16上是AN4，所以将是不同的。但是，代码生成器生成的外围设备和代码的初始化呢？这也需要改变吗？谢谢

    Hi there,

I'm working with a customer which has a board developed around the PIC12F1571. Now, they want to add more functionality by adding a UART. Since all the pins are being used, it's not possible to just change to the PIC12F1572. Instead, we're looking for a code compatible PIC but with more pins. In the product matrix on the microchip website, the PIC16F15323 was the first to appear with 14 pins and 1 UART. As seen on the datasheet, the top 8 pins are the exact same as the PIC12F1571; on the bottom, they add PORTC pins, which can be mapped with the UART.

My question is: is the code compatible between the two? Is it just a matter of changing the target micro and the code works or nothing works? I'm seeing that, for example, the RA4 pin on the PIC12 is the AN3 channel of the ADC, but on the PIC16 it's the AN4, so that will be different. But what about initialization of peripherals and code generated by the code generator? Does that need to change too?

Thanks
