Hello List! Anyone of the experts here has made a simple circuit to test the MCP2120 .... really I need this bit Encoder/Decoder to work . The problem is that I am a programmer with simple basics of electronics ...I don`t know about the circuit design so I am looking for a simple working circuit ....I have checked all the datasheets and the App. Notes but I couldn`t find even one simple circuit .... I tried to use the schematic of the MCP2120 Dev. board from Microchip and delete the unwanted parts but still I can not get it working ..... I `m gonna be crazy :((((( .... the serial transmision is working well but the IrDA transceiver or the chip MCP2120 is not working properly .... Any good Engr. who can help please ..... I am using the following parts: 1-MCP2120 with Osc. 7.3728 (9600 bps) 2-PIC16F873 with Osc 4MHz 3-IrDA transceiver HSDL1001 4-LCD to display data. would I get this circuit working? I am just wondering!!? thanx in advance. Salah. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
