![]() ![]() Īfter the driver for CP2102 was installed, a few sample Arduino sketches such as "Blink" and "Fade" were uploaded to make sure the chip was still functioning before designing the board in Eagle PCB. 0.1uF capacitor x 1 between module's DTR pin and RESET (chip pin 30).CP2102 USB to UART TTL Module (one that has a DTR pin), with the connections:.16MHz ceramic resonator connected between chip pins 33 and 34, with resonator's ground pin connected to chip's GND.LED x 1 and 1k current limiting resistor x 1 connected between D/13 (chip pin 26) and GND, this is same as the Arduino Mega "L" LED, to be us as indicator to test prototype.10k pull-up resistor x 1 connected between RESET (chip pin 30) and VCC/AVCC.These are internally translated to portadress and bitnumber. If you want to use digitalWrite () you must use the Arduino pin numbers. These are only bitnumbers of the corresponding PORT - eg PORTB. Additionally, there are two latest pins located near the RST pin. 0.1uF bypass capacitor x 3, connected in parallel to 3 of the VCC/AVCC and GND pairs (chip pins ). You cannot use PAx or PBx in digitalWrite commands. The SCL & SDA pins of Mega 2560 R3 board connects to beside the AREF pin.ATmega2560 chip from an Arduino Mega2560 clone (functional chip and bootloader) removed with a hot-air gun, soldered on to a TQFP100 breakout PCB.AVR 2560 : C’est le contrôleur principal utilisé pour programmer et exécuter la tâche pour le système. Arduino Mega R3 a un régulateur de tension pour 5v et 3,3v d’alimentation pour le contrôleur Arduino et l’alimentation du capteur. A prototype board was made as proof of concept, the components, placements, and connections are: L’alimentation externe pour Arduino Mega de la gamme 7-12 volts est donnée avec ce port. ![]()
