• Issue with external oscillator and SMBus interrupt
    Hello, I've got an issue when I use a low external frequency (32kHz) on C8051F350. In classic case, this frequency is used to have a very low consommation. I would like to switch to internal 3.0625MHz...
  • XTAL Oscillator
    It is said that 8051 has an on-chip oscillator but requires external clock to run it. What may be the internal circuit for on-chip oscillator, how it runs after connecting crystal oscillator? Also what...
  • RTC with external 32.768kHz oscillator on lpc2378
    I'm trying to use the RTC on my MCB2300 with Keil IDE. The NXP example is only using the internal clock. My initialization seems to be ok, according to the lpc23xx manual. But I'm facing 2 issues. First...
  • LPC2388 RTC configuration for External Oscillator
    we are using the MCB2300 Development Kit in Keil IDE to configure the RTC to external Oscilltor. But it is not working. Please Help me to send the configuration setting c sample code. Thanks...
  • RC Oscillator with P89LPC932
    Good morning, When power on reset, the SFR Trim register is loaded with a factory pre-programmed value to adjust the RC oscillator to 7,37 MHz. I would like to know if this factory pre-programmed...
