![]() ![]() I thought the PIC is not able to supply the current demanded by the drivers so I tried inserting, progressively, resistors of 22 Ohm, 33 Ohm, 100 Ohm and 1kOhm. Wondering if this could be the reason both pins of the PIC go high. After programming the PIC with the Pickit2 programmer, the PIC responds well when out of its application circuit (that is when disconnected from the drivers).When connected to target circuit, the pins (CCP1 and CCP2) stop working and all go high. I am using the PIC18f252 together with two IR21844 MOSFET drivers. I am trying unsuccessfully to drive the n-mosfets in my H-bridge inverter. PIC18f252 and IR21844 mosfet gate driver problem ![]()
