Can No Longer Program ATmega chip with Arduino ISP
2024年10月10日 · it is not normal, you can try to erase chip and write correct fuses, and check if it reads correct now. You are correct. if all fuses read 0x0, that also means that external reset disable has been set, which means you can no longer pragram the chip.
TTL to RS232 with a MAX232 chip - question - Arduino Forum
2024年10月20日 · On my PCB there will be an Arduino Nano ESP32, with a MAX232 chip with some capacitors where needed according to the datasheet. Question is about the Data GND pin. I haven't been able to measure if the GND and Data GND are internally connected on the GPS, but since i'm using the 12v and GND to power my arduino , it all will have the same grounding.
