RT809H + GT34C04 Fail !

Propretor · 发表于: 2020-4-11 14:17:39

What is the problem with the RT809H removing write protection from a supported GT34C04 chip?
I took an oscilloscope and looked at the voltage on 1 pin while reading and writing.
Even when recording, there is a pulse of only 3.3V, nor any 7-10V. That is, the device CANNOT overwrite the GT34C04.
I applied external + 12V power to the RT809H. At the first contact 7-10V did not appear!
Overwrite data failed!
Developers, please solve the problem!
Best Regards.

How to make "clear write protection" command?

Are there any developers here? Thanks.

為什麼沒人回答？

刪除GT34C04芯片上的寫保護的問題
我拿了示波器，在擦除過程中查看了1針的電壓。
只有3.3 V的脈衝。沒有7-10 V的脈衝。
RT809H無法覆蓋GT34C04 ！！！
我為RT809H施加了+12 V外部電源。在第一次接觸時，也沒有7-10伏電壓。
覆蓋數據失敗！
RT809H是否支持從支持的芯片列表中刪除GT34C04芯片的寫保護？
最好的祝福。
