When replacing a different chip, it's important to tin the chip pins after which solder them to the hash board. Utilize thermally conductive gel evenly about the chip’s area, then lock the heatsink.
Open up MPLABIPE and choose product: PIC16F1704, simply click ability to pick out the facility provide method, then simply click function. Step one: select file to find the .HEX file to get programmed; The second action: click connect with join normally; The third action: simply click the program button, and soon after completion, simply click verifiy to prompt the verification to demonstrate that the programming is prosperous. Figure 5-7 Determine five-eight Forth move: Verify the Enhance circuit output
② Visually inspect whether or not you can find noticeable signs of burnt elements, elements influence offset or missing pieces, and many others.
8V ranging from the initial chip. Should the serial port stops long-phrase Procedure once the brief circuit, the primary chip is performing appropriately.
If the chip’s look isn't broken, the chip with the bottom response amount in Just about every area really should be replaced.
c) In the event the hashboard however displays the X and decreases the hashrate, you may clear away the warmth sink with the hash board for mining. When the hashrate is decrease, evaluate whether or not the domain voltage is standard.
If there is absolutely no 3.3V output, Check out the connection position from the hash board tester cable and also the hash board.
b. Verify whether the inlet air temperature with the miner is just too large, and confirm which the exhaust air is easy.
APW12 energy provide: AP12_12V-15V_V1.2 and energy adapter cable. It is usually recommended to use thick copper wire to the good and detrimental poles of the facility supply to connect the ability offer and the facility board and only restricted to PT1 and routine maintenance examination use.
Measure regardless of whether There exists output on the next pin of U3 as well as the voltage is about three.3V; if Sure, please continue to troubleshoot the condition; if there is not any 3.3V, make sure you check the link standing of the hashboard tester cable plus the hashboard is Okay, and reprogram the PIC.
d-one) The very first scenario: the take a Buy Here look at time is largely the same as The great board (usually the worth of X won't modify every time you test) (check time refers back to the time from when the start exam button is pressed to the result of ASICNG: (X) displayed over the Liquid crystal display).
Make sure you watch out to not imagine any impostors, remember to Test our appropriate Speak to data and beware of remaining deceived finding scammed, and dropping money. please Test our right contact way: Below
a-3) Measure the resistance of R8 or R9 that has a multimeter to examine whether it is inside of ten ohms as well as the looking at won't leap randomly. Otherwise, be sure to change both of these resistors. a-four) Test In case the pins of the initial chip are certainly not soldered perfectly (it absolutely was present in repair that the pins are tinned observing within the facet, though the pins are not stained with tin at all in the event the chip is taken out). b) If a single chip are available in action a), it signifies that the very first chip and also the preceding circuit are excellent. Use an analogous strategy to examine the next chips. As an example, short-circuit the 1V8 exam level and the RO check level concerning the 38th and 39th chips. In case the log can discover 38 chips, the very first 38 chips have no issue; if you still obtain 0 chips, Examine the 1V8 1st; if It truly is usual, this means that there's a problem Together with the chip soon after 38. Proceed to research with dichotomy right until the problematic chip is discovered. Assuming that there is a problem with the Nth chip, when the 1V8 and RO among the N-1th and Nth chips are quick-circuited, N-1 chips can be found, but in the event the 1V8 and RO between the Nth and N+1th chips are brief circuited, the complete chip cannot be discovered.
● Once the plan test is handed (the shorter-circuit check of the general schedule check is necessary to steer clear of the chip or other materials becoming burnt due to small circuit when the ability is turned on), the chip check may be executed While using the hash board tester, as well as positioning may be determined in accordance with the take a look at result of the hash board tester. ● Based on the displayed effects on the hash board tester detection, ranging from in close proximity to faulty chip, Test the chip check details (CO/NRST/RO/XIN/BI) and voltages which include VDD0V8 and VDD1V8. ● In accordance with the signal move, apart from the RX sign, reversely transmit the sign (from No. seventy six to No. one chip), many from the indicators such as CLK CO BO RST are forward transmission (one-seventy six), along with the irregular fault stage can be found with the power provide sequence.
