Bitcoin is soaring; which altcoins will generally rise? The world of cryptocurrencies is developing at a breakneck pace. As interest in digital assets increases, investing in the right cryptocurrency can provide an excellent opportunity to earn high returns. Unfortunately, whether you are an experienced investor or a beginner, navigating the complex world of decentralized currencies can be difficult. But don't worry; we've got you covered! This article will reveal the top six cryptocurrencies to consider buying in 2023. MATIC Polygon, formerly known as Matic Network, is a blockchain platform that facilitates the development and scaling of Ethereum infrastructure. It transforms Ethereum into a multi-chain system and provides a common framework for developing various types of applications. Besides that, Polygon SDK can be used to create optimistic rollup chains, ZK rollup chains, and standalone chains. The platform can process up to 65,000 transactions per second on a single sid
How to use online debugging PICKit 3.5 programmer to reprogram the hash board PIC file?
The PIC chip (such as PIC16F1704, PIC12F1572) on the Antminer hash board is one of the very important parts, which is used to store the chip and voltage data of the hash board. If the data of the PIC chip is damaged or lost, the hash board will not work, and the entire miner will not be able to operate normally and profitably.The in-circuit debugging PICKit 3.5 programmer with firmware self-recovery function can be used to re-program the PIC file of the hash board.
Next, I will explain in detail how to use the PICKit 3.5 programmer to burn the PIC file of the hash board?
1. Before starting PIC file burning, you need to download and install the burning driver: MPLABX-v3.10-windows-installer.exe
2. Open MPLAB IPE V3.10, and select the PIC chip that needs to be reprogrammed. Here we will take PIC12F1572 as an example.
3. Click File to select the corresponding program, and then click Settings.
4. Enter the password "microchip" in the new interface to enter the advanced settings page.
5. As shown in the figure below, select Power, then select 3.3V for VDD, and check ✔ Power target circuit from Tool.
Notice:
Here is an example of the PIC12F1572 chip, so VDD should be 3.3V. If it is a PIC16F1704 chip, it should also choose 3.3V, but if it is a PIC16F1705 chip, it needs to choose 4.8V for programming.
6. Click Operate, and reconfirm that the data serial port of the PICKit 3.5 programmer is properly connected to the computer.
7. The hash board no need powered on, then connect the PICKit 3.5 programmer to the hash board Pin 1. As shown below:
8. Then click Connect, when the MPLAB IPE warning appears on the interface, click OK.
9. Finally, click Program to start programming.
In addition, if you want to program the next PCBA continuously, you need to reconnect the PICKit 3.5 programmer to the hash board correctly, and then click Program to start burning. To view the burning information, click Read.
The above are the specific operation steps for re-burning the PIC file of the hash board using the PICKit 3.5 programmer. The PICKit 3.5 programmer can quickly repair the failure of the hash board due to damage or loss of PIC chip data, so that the miner can quickly resume normal operation.
