我正在尝试为基于SPI的IO扩展器创建通用驱动程序.我们的想法是在实例化中传递初始化值,该初始化值与请求的IO设置相匹配.
我目前的尝试看起来像这样:
entity max7301_simple is
generic (
IO_cfg : array (1 to 7) OF integer range 0 to 255 := (16#55#, 16#55#, 16#55#, 16#55#, 16#55#, 16#55#, 16#55#)
);
port (
-- Application interface :
clk_i : in std_logic; -- input clock, xx MHz.
rst_i : in std_logic; -- sync reset.
en_i : in std_logic; -- enable, forces re-init of pins on MAX7301.
output_i : in std_logic_vector(27 downto 0); --data to write to output pins on MAX7301
irq_o : out std_logic; …今天终于到了火花板边缘板;-)
按照这个写得很好的指南：https : //codelabs.developers.google.com/codelabs/sparkfun-tensorflow/#3 我在尝试使用uart_wired_update.py脚本在 Ambiq 上刷写代码时遇到了以下 NoResponseError张量流示例
