Ayke van Laethem	16d2b71820	all: do not use machine.TWI_FREQ_* constants ... These constants were always a bit weird: * they use an uncommon name (TWI instead of I2C) * they don't follow Go naming conventions (CamelCase) * the constants don't provide much value: their name is their value (100KHZ => 100e3). Therefore, I propose we remove them and replace them with regular numeric constants.	2021-02-06 11:21:37 +01:00
