Today, with the rising σ♠±λlabor costs, many el♥ ¥ectronics manufacturers are lookin←§g for efficient chip α÷γ×programming solutions to save labor co×→♥≥sts and improve produ☆​ct competitiveness. SFLY SP8-¶®$F high-efficiency offl​≥ine mass production progr♥™ ammer uses high-speed 32. ARM pro↑→β×cessor, built-in 128♦ ‍Mbit data memory. Speci$× al IO processing for the chip. The pro"♣gramming speed is much higher than ot'≠φher common programmers of several thou±♠÷sand dollars, becoming an ideal solut→ ♠©ion for mass production customers.
Some customers mistakenly bel÷ 'ieve that to mass-produce pσ¶δφrogramming, you should choose a prog€×rammer with a drag and drop. In fact, ¥‌this is not the case. This article wλλill compare the SP8-F programmer with÷≥£ other programmers in one §₹¥aspect.

Operating speed

The above parameters are assumedδ→ to be ideal, that is, the chip i±<s placed correctly, the chip↓‌δα pins are in good contact, and all↑←σ 8 chips will be successfully →←÷programmed. Later, it will beΩφ€× mentioned that the wrong dire↑≠ction of the chip or t™♦πhe poor contact of the pins ‌© βin the one-to-eight mδ★♦odel The resulting ad ↑verse effects.
The 1 to 8 models pur‌§γchased by the customer ar↕♦¥e programmed in synchronous​←™ mode (in fact, 1 drag 8 on tλ₽∏he market is basically £γ₩in synchronous mode), and ☆€all the chips need to be pl"&€aced before programmσφ'™ing.
The verification of this model a✘€dopts the time-sharing opera¶εtion mode, that is, the built-₽λ>in CPU first reads a piece of data from ∞γ the SD card, checks it wit↔£h 8 chips, and then reads a part€↑ of the data and checks each chip sepa™↓σrately.
Time spent writing all 8 ←±chips: 57S, average time per ♦<♠chip: 7.1S
SP8-F cluster operation mode
 
We assume that the customer uses four ♥£SP8-Fs for cluster operation, ‍©↕♣and all programmers work independ÷✘ently without affecting each other.
We can place a chip or take a chip ←↑✘when one of them is programming.≈룩
As can be seen from the above figurδ₹e, basically the operato∞↕'r is only constantly∏"££ putting chips and taking chips, a€∑nd the programming operati∑± ↑on does not take up the op☆€ erator's time.
SP8-F cluster mode writ₽&¶€es 8 chips and takes time:¶↕εσ 43S, average time per time: 4.5S

Overcurrent/short cir∞‍≤✘cuit protection
In the one-to-eight mod<™el, all the chips being≥γ✘& programmed are powered by the sΩ​≈ame power supply. If the operat£ ₹or accidentally puts one of the ch₽↓ ips in the opposite direction, or ™Ωλone of the chips is bad,×≤↑ all the chips will fail to program. A‍σ÷πnd the drag and drop of the eig§"₩♣ht machines can not accurately te ★☆ll which chip has a proble♦∞σm, the user can only remove× ₽✘ all 8 pieces, and th ★¥→en check one by one. Time-consu£∞γming and laborious.
All SP8-F machines ope​∏πλrate independently and are powered ↓✘$separately. Each mach≥'™←ine is equipped with a shor ₹↕t-circuit/overcurrent protection fφ≈←unction. When the chi∏∞p is reversed or bad, it ca★Ωλn accurately report errors in ®↓±✘time and without affecti×™ng each other.

Pin contact detection
SP8-F has pin contact failure &♦•detection, and automatically ×>detects the chip pin contact state in$•β≠ offline mode. The pr♠≤>ogramming operation will start on∏φly when the chip pins areσ≠÷≥ in good contact.
One-to-eight models do not have thλ≤→e pin contact detection functio 'αn. When the chip pins are no↓<π÷t in good contact, the error can o¶Ω≤nly be reported at the end of th§​φ•e chip programming. This leads to ↔β♥unnecessary time wastage.

Convenience
SP8-F has built-in o₩ Ω≈ffline memory, no need to use SD ca×¥​∞rd or master chip. After using the PC ± ®"software to download data,₩™↑↓ the programmer can work ₩πδ₽independently from the computer. No nee ↕&d to make any settin≤∑gs for offline work, just put theε¶ chip and take it. The chip canα★£‌ be used, even the star↓↔φt button is not needed. The pro§δ♠'grammer will use the b♦<¥σuilt-in buzzer and multi-cπ₩olor LED indicator to p≈↓→rompt the results. The use is ve"δ∞✔ry simple. Ordinary ∞Ω¥workers will use.
One-to-eight operation is r©★elatively cumbersome, you ≈∞'need to use the mother chip or SD c "ard, and ensure the data ac∑★<♣curacy of the data fil ☆e or the master. In the offline operat♦₹ion, you need to set the≠± corresponding settings'★™α. If the settings are not cor<&©∞rect, it will be possible. All the chφα¶ ips that caused the programmi≥✘ ng are not working properly.

Online programming fun¶σction
SP8-F can also be conne≠∏cted to a computer operati ♥≠≥on, and its speed is basically no dif¶♠§ferent from offline operation. It has "® ‍more flexibility in engi→✘neering development and small batch pλ¥rogramming.
Most of the one-to-eight models do not↔≈φ support online operations. Even w♣≤✘ith this feature, the speed is v↕↔←•ery slow and there is not m"λ≈®uch use value.

Value for money
If the customer uses ‌Ωα×4 SP8-F programmers for cluster o↑γ∏peration, the cost is abou↔®±€t 1800 yuan.
At present, the market is one →∞for eight models, the price is&α≤ 2000~3500 yuan.

In Conclusion
SP8-F is superior to the tradiφ≈tional one-to-eight mΩ₽δode programmer in terms o  f programming speed, '‍±αease of use, cost performance and fle÷λ∑xibility.
