The following projects were made for the Low Layer driver (which is part of the HAL driver) and hosted at sourceforge.net as SVN repositories (I don’t do well with git) – under linux I use RapidSVN client. In the light of the new events, I decided to convert them to the SPL driver and my move in using this driver is permanent. The repositories were deleted I have here a backup. The list contains the following projects (that will be prefixed at the time of conversion with spl_ instead of ll_):

1. – ll_blink – blinks a LED with blocking delays;
2. – ll_blink_nonblocking – blinks a LED with non_blocking delays (similar to Arduino millis);
3. – ll_ds18b20_single_lcd – displays on LCD the temperature and displays also the ID of the sensor;
4. – ll_ds18b20_multiple_lcd – displays on LCD the temperature of two sensors, where the IDs are known from the project nr.3;
5. – ll_lcd4_hello – displays a text and a numeric counter on a 2×16 alphanumeric LCD;
6. – ll_library – this is just a container where are stored additional libraries that are used by the projects;
7. – ll_max44009_test – measuring the light intensity in LUX using the hardware I2C peripheral;
8. – ll_max44009_test_sw_i2c – measuring the light intensity in LUX using the software I2C;
9. – ll_pcf8583_clock_lcd * – displays the time and data on LCD;
10. – ll_pcf8583_clock_lcd_sw_i2c – displays the time and data on LCD using the software I2C;
11. – ll_pcf8583_daily_alarm_lcd – displays the time and data and sets and sounds a daily alarm;
12. – ll_pcf8583_daily_alarm_lcd_sw_i2c – displays the time and data and sets and sounds a daily alarm using the software I2C;
13. – ll_pcf8583_weekdays_alarm_lcd – displays the time and data and sets and sounds alarm in certain days of a week;
14. – ll_pcf8583_weekdays_alarm_lcd_sw_i2c – displays the time and data and sets and sounds alarm in certain days of a week using the software I2C;
_______
* – the pcf8583 is a real time clock that connects on the I2C bus and where is not specified, is about hardware I2C implementation.
