器件型号:PGA305你(们)好
感谢你的帮助。
我正在成功读取运行时 PADC 和 TADC 值。 但实时补偿值全为零。
我关注的是"表9. I2C 传输示例" 数据表第33页。 下面是我发送的字节序列:
S 0x40 0x09 0x04 RS 0x40 0x04 RS 0x41 ->读取"0x00"
S 0x40 0x09 0x70 RS 0x40 0x04 RS 0x41 ->读取"0x00"
S 0x40 0x05 RS 0x41 ->读取 "0x00"
以下是 EEPROM 内容:
0 1 2 3 4 5 6 7 8 9 A B C D E F
00 - 0F:00 00 20 00 00 00 00 00 00 00 00 00 00 00 10 00
