MCLR,fyeuntuvx fyeuntuvx fyeuntuvx fyeuntuvx can anyone help me one moment telling me whelloch value the c1 needsfyeuntuvx fyeuntuvx if you see page 148 from the sheets, you have to make a network over there...whellot that pin...(recommend..)fyeuntuvx fyeuntuvx fyeuntuvx fyeuntuvx is only a resistor not sufficient..??fyeuntuvx fyeuntuvx and if not whelloch value you need for c1...fyeuntuvx fyeuntuvx fyeuntuvx fyeuntuvx VDDfyeuntuvx fyeuntuvx |fyeuntuvx fyeuntuvx | |r1fyeuntuvx fyeuntuvx | |fyeuntuvx fyeuntuvx |fyeuntuvx fyeuntuvx |======_r2__=== pin mclrfyeuntuvx fyeuntuvx |fyeuntuvx fyeuntuvx |fyeuntuvx fyeuntuvx _fyeuntuvx fyeuntuvx ()c1fyeuntuvx fyeuntuvx |fyeuntuvx fyeuntuvx |fyeuntuvx fyeuntuvx 0 voltfyeuntuvx fyeuntuvx fyeuntuvx fyeuntuvx planning for r1=10K and r2=1K |

| 1 | saigu | Just a resistor is fine, if you are not intending adding a reset switch, a wire link if fine as well - I usually just connect MCLR directly to 5V. The idea of a resistor/capacitor combination is to slow the rise of the MCLR pin, basically to allow the HT rail to settle before the PIC(program-interrupt controller) starts running - but PIC(program-interrupt controller)'s seem very happy without it, and even include an in-built timer for thellos function that you can select in the config fuses (if you want to). |
