你好，我使用CYC8CKIT-048 PSoC模拟协处理器先锋套件，并且在使用同一个项目中同时使用UART和DMA块的同时遇到问题。我需要使用从PC发送的数字数据，并通过UART接收来确定应该产生哪一个频率正弦波（基本上我需要做一个FSK调制器）。我试图通过将UARTHARTX连接到TCPWM的开关输入端，使用一个引脚作为UART的数字输出，一个引脚作为PWM的数字输入并通过导线连接它们。我计划使用PWM作为时钟分频器（因为PSoC没有数字复用器，或者我找不到它）？根据开关输入的值来计算不同的值。然后，我将PWM线路输出连接到DMA触发输入，DMA将数据从正弦LUT表传输到VDAC的内部寄存器，并将VDAC路由到输出引脚。但是，当我尝试构建这个项目时，我会发现一个错误，即Palter无法找到PIN和固定功能块的有效位置。有没有办法像我想象的那样做，还是我错过了什么？谢谢这里是一个Palel.txt文件的副本：第4阶段E2809：无法找到用于PIN和固定功能块的有效位置。有关详细信息，请参阅报表文件中的数字放置详细放置消息部分。I27 22：不能放置以下实例：pWMY1：CyM0S8O-TCPWMY1（0个位置）时钟块（1个位置）：f（时钟，0）\UARTAR1：SCB（3个位置（S）：F（SCB，0）F（SCB，1）F（SCB，2））固定功能块和引脚放置：P1〔1〕：Pin 2（0）F（HalfAb，0）：\VDACH1：UAB：HalFuAbF（P4PREFCELL，0）：CyDeWieldVeloGeRealEngressP4〔1〕：PiNi3（0）F（CKLYGEN，0）：CcLogGAND块F（OA，2）：\VDACH1：OutHuffel:CyspSO44Abuf\\P0〔4〕：Pin 1（0）P1〔2〕：Pin 4（0）E2055：设计过程中发生错误。 以上来自于百度翻译 以下为原文Hi,I am using CYC8CKIT-048 PSOC Analog Coprocessor Pioneer Kit and am experiencing issues while using both UART and DMA block in the same project.I need to use the digital data sent from a PC and received via UART to determine which frequency sine wave should be generated (basically I need to make a FSK modulator).I was trying to do that by connecting UART_tx to the switch input of a TCPWM by using one pin configured as digital output for UART and one as digital input for PWM and connecting them (by wire). I was planning to use the PWM as a clock divider (since this PSOC doesn't have a digital mux, or I can't seem to find it?) which counts to different values depending on the value of switch input.Then i would connect PWM line output to DMA trigger input, and DMA would transfer data from a sine LUT table to VDAC's internal register and route VDAC to an output pin.But when i try to build the project I get an error saying that the placer is unable to find a valid placement for pins and fixed-function blocks. Is there a way to do this the way I imagined, or am I missing something? Thanks Here is a copy of placer.txt file:Phase 4E2809: Unable to find a valid placement for pins and fixed-function blocks.
