PASS or FAIL 5VDC signal stays on until the next test. Is there a way to reset the device other than a 120VAC power cycle to where neither the PASS or FAIL light is on going into the next test?
You can use ICP DLL functions to turn off the LEDs after programming is completed: err=Icp2PinState(G3_GPF_OUT_PASS, PIN_LOW, &pin_state); //PASS/FAIL outputs err=Icp2PinState(G3_GPF_OUT_FAIL, PIN_LOW, &pin_state); //+err=Icp2PinState(LED_INT_PASS, PIN_LOW, &pin_state); //PASS/FAIL LEDs err=Icp2PinState(LED_INT_FAIL, PIN_LOW, &pin_state); //+err=Icp2PinState(G3_LED_PASS_EXT, PIN_LOW, &pin_state); //PASS/FAIL LEDs (ICP2GANG/COMBO) err=Icp2PinState(G3_LED_FAIL_EXT, PIN_LOW, &pin_state); //+
Reset IC STM1001 on VPP/MCLR
The STM1001 generates a reset pulse lasting up to 140 ms after applying +5V, which may conflict with the T_VPP(RESET) of the ICP2(G3). Try increasing the Vdd-to-Vpp parameter from 4 ms to 250 ms (perform debugging in full PC-driven mode). In the future, add a 1 kΩ resistor between the STM1001 and the MCU to […]
