STC89C52 Ontwikkelingsraad, Leren Systeem Board C51 LCD1602 8051 MCU Controller Systeembord

Das Entwicklungsboard ist genauso wie beschrieben. Nicht mehr und nicht weniger.Abgesehen von der Behauptung 'Support for online learning'. Das stimmt nur für chinesischsprachige User.Einen Punkt muss ich abziehen, weil absolut keine Software (CD, oder USB Stick) dabei ist.Einen weiteren Punkt für den Onlinesupport, weil die Webseite der Herstellerfirma (Prechin) fast ausschließlich auf Chinesisch ist. Und gerade für diese Variante gibts auch im Web nicht besonders viel Information. Über den grösseren Bruder HC6800EM3 gibt es wesentlich mehr, und das hat mir sehr geholfen.Wer ersten Kontakt mit Entwicklungssystemen bzw. diesem Prozessor hat, empfehle ich, vorher woanders Erfahrung zu sammeln.Aber wer diese schon hat, für den ist es eher geeignet. Das Gehäuse ist praktisch, der Preis ist gut, und für mich hat es gepasst.

This is a hardware kit that appears to be used in Chinese schools for exercises in microcontroller programming. It's probably good at this, and it appears to be on sale in many places. However, if you don't speak Chinese or don't want to do do the tutorial experiments then it's utterly useless.A look at the board shows it's hard-wired to some hardware used for the exercises. You could conceivably use it as a programmer for the 40-pin 89C52 MPU and then transfer it from the ZIF socket to a breadboard if you wanted to do your own thing. A request to the supplier as to where the programming software could be obtained resulted in an incorrect or unintelligible answer.I have development kits for most embedded CPUs available (IAR/PIC and so on) but none recognized it when I tried in desperation.This should not be on sale, as it's unsuitable for the purpose advertised. Unfortunately I was strung along by the supplier long enough that I cannot now return it. Amazon should withdraw it, or at least demand it has an accurate description - it is not a development board and it has no English language documentation.

Ricevuta in 48h, sembra una buona scheda di sviluppo, ricca e completa a pochi soldi (circa 35€ spedita), ma purtroppo non è accompagnata da CD o altra indicazione web su dove si possa trovare la documentazione del caso... ci sono solo due QR-CODE sulla scatola, ma fanno riferimento al forum del produttore e sono due link errati. Il produttore è il cinese prechin.net che ha un sito approssimativo e solo in inglese, anche usando chrome con il traduttore si combina poco... questo modello poi non esiste sul portale... che dire, peccato davvero, poteva essere un buon affare, ma così la dovrò restituire se il venditore non mi risponderà...

I brought this, to improve my learning of Ansi C, using a moden classic of the old 8051.From what I have found researching this WICKED little development board, this has some wonderful goodies to work out. I even got a bonus, an extra little LCD along with the standard 16x2 LCD.This is So easy to program, I've included a little smiley face displaying on the LED 8x8 dot matrix.PRECHIN you've got some very nice boards.What can I say but cheers. Happy days ahead.
