An excellent microprocessor from the M2 series of PICAXE chips. The 18M2+ chip features 16 configurable input/output pins [16 usable pins + 2 pins for voltage/gnd = 18 pins] and harnesses new Microchip PIC technology including: internal temperature sensor, Manchester radio encoding by use of simple commands [rfout, rfin], additional memory, time-sliced parallel multi-tasking of up to 8 tasks, etc. I haven't been able to use all the features of the 18m2+ yet, but learning the PICAXE BASIC language was a snap and this microprocessor was a good lead into my new hobby of microprocessors and interfacing. My first project utilized the 18m2+ to SIMULATE a BCD to 7-Segment [4511] plus decade counter [4517]. I used pinsB as outputs to the 7-segment, 4 of the pinsC as binary input, and the rest for signaling the 'counter', a software 'reset' pin, etc. The PICAXE platform offered me multi-tasking/time-slicing, free PICAXE Editor 6 software, directives, symbols, variables, input, output, pins, interrupts, "lookup" table command, integer math, an internal 1 second timer, etc. The possibilities are endless!

Un excellent * microcontrôleur * de la série M2 de puces PICAXE. La puce 18M2 + comprend 16 broches d’entrée / sortie configurables [16 broches utilisables + 2 broches pour tension / GND = 18 broches] et exploite la nouvelle technologie PIC de Microchip, notamment: capteur de température interne, codage radio Manchester par l’utilisation de commandes simples [rfout, rfin] , mémoire supplémentaire, multi-tâches parallèles découpées dans le temps jusqu’à 8 tâches, etc. Je n'ai pas encore pu utiliser toutes les fonctionnalités du 18m2 +, mais l'apprentissage du langage PICAXE BASIC était un jeu d'enfant et ce microcontrôleur était un bon élément pour mon nouveau passe-temps, celui des microcontrôleurs et de l'interface. Mon premier projet utilisait les 18 m2 + pour simuler un compteur BCD à 7 segments [4511] plus un compteur de décennies [4517]. J'ai utilisé les broches B comme sorties sur le segment 7, 4 des broches C comme entrée binaire et le reste pour signaler le compteur, une broche de réinitialisation logicielle, etc. Pour mon projet, la plateforme PICAXE offrait plusieurs tâches / logiciel PICAXE Editor 6 gratuit, découpage dans le temps, directives, symboles, variables, entrée, sortie, broches, interruptions, commande de tableau "lookup", calcul du nombre entier, minuterie interne de 1 seconde, etc. Les possibilités sont infinies!

To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
