WebThe HSI oscillator can be trimmed by ±4.5% by writing the 5-bit value to the HSITRIM register. This trim value is set to 16 after any reset. Increasing this value by 0x01, increase the period of the oscillator by approximately 0.3% on STM32 products. The trim value is not perfectly linear versus the HSI16 clock frequency, this is due to process Webabove 5 MHz, there is too much instability to keep the drift under 5 Hz per minute. In order to build a low drift VFO for 40 meters or above, a low frequency VFO is "converted" up to the desired high frequency. This is done by adding the VFO to a high frequency crystal oscillator signal and then filtering out the sum frequency.
