To write the new Voltage Divider value can be programmed as follows: - SubclassID for “Voltage Divider” is 104 or 0x68 hex, and offset is 14 - Write 0x00 using BlockDataControl() command (0x61) to enable block data flash control. (wr 0x61 0x00) - Write 0x68 (Calibration Subclass) using the DataFlashClass() command (0x3E) to access the Registers subclass. (wr 0x3E 0x68) - Write the block offset location using DataFlashBlock() command (0x3F). To access data located at offset 0 to 31, use offset = 0x00. For example, Voltage Divider (offset = 14) is in the first block so use (wr 0x3F 0x00). - To read the data of a specific offset, use address 0x40 + mod(offset, 32). So to read the old Voltage divider (rd 0x4E old_Voltage Divider_MSB) (rd 0x4F old_Voltage Divider_LSB) - To write the data of a specific offset, use address 0x40 + mod(offset, 32). So to write the new Voltage divider (rd 0x4E new_Voltage Divider_MSB) (rd 0x4F new_Voltage Divider_LSB) - The data is actually transferred to the data flash when the correct checksum for the whole block (0x40 to 0x5F) is written to BlockDataChecksum() (0x60). (wr 0x60 NEW_checksum) The checksum is (255-x) where x is the 8-bit summation of the BlockData() (0x40 to 0x5F) on a byte-by-byte basis. A quick way to calculate the new checksum is to make use of the old checksum: (a) temp = mod (255 – OLD_checksum – old_Voltage Divider_MSB - old_Voltage Divider_LSB), 256)(b) NEW_checksum = 255 – mod (temp + new_Voltage Divider_MSB + new_Voltage Divider_LSB, 256) Step 3. Update any individual flash locations, such as serial number, lot code, and date: In a similar manner to the Voltage divider, any pack specific data such as serial number, lot code and date can be changed during the production process.

介绍 1、用QQ，小于2G还行，再大了就不行了，这个可以 2、用QQ，得需要Internet，而这个就不用了 3、很多个性化的提示，自己找找吧^_^ 4、开源，不要分~~ 要求： 多给点鼓励呀~呵呵

如想要图片上的雕花图案，用于设计材料上的雕花，可将图片转出cad的描边工具

对应自控电气实验的仿真文件，，之前那个我上传的免费资源，但是后来发现下载需要下载码，我也搞不清楚这个下载码是啥，所以这次上传带积分的，想下载的话1积分，如果没有的话去某宝（你懂得）几毛钱。本意是想免费开源，但是最终还是要积分下载。
