EEPROM problem with DG128

LD128 EEPROM mapping problem, studied for a few days, no research understands, finally decided to use PE, use PE to automatically map the EEPROM, EPROM address is: 0x1800~0x1FEF, 2KB space; RAM: 0x2000~0x3FFF, 8KB Space, and can successfully read and write EEPROM, but has added their own code, and added their own write interrupts in the code automatically generated by PE.

If it is DG256, there is no need for address mapping. By default, 3KB of EEPROM is available, and DG128's 2KB EEPROM is invisible.

Upload an example of an EEPROM generated with Processor Expert.

The next step is to FLASH, but unfortunately my license is not enough, you must write your own program, huh, huh, have time to play with FLASH, by the way also write the S12 CAN code, huh, huh

As LCD display in YFJ company that we usually use it to military grade battery ,especially Lithium-ion batteries ,for these battery applications ,we have obvious advantage is that we focus more on shor circuit protection which we follow the US military standard.

Short circuit protection:The following test shall be performed. Charge batteriesas specified in  ; use of 4.6.3 is permitted. Measure and record the OCV. Short each battery across all the positive and negative terminals with a total external resistance not greater than 50 milliohms. After one hour remove the short from across the terminals. Measure and record the OCV. Stabilize batteries at the normal conditions of 4.3.1 for not less than 2 hours. Chargebatteries in accordance with 4.6; use of 4.6.3 is permitted. Stabilize batteries at normal conditions for not less than 2 hours, then discharge the battery in accordance with 4.7.2.3. The battery shall meet the requirements of 3.7.2.3.
