I made this device in 1997;
1. EXOline protocol on RS-485
2. I2C to talk to EEPROM with calibration parameters.
3. SPI to talk to D/A converter
4. 1-wire to communicate with up to 8 external DS18B20 temperature sensors.
All done in a Microchip PIC16C73, which has 192 bytes and 2k PROM.
a. maximum size of EXOline packet is ~240 bytes, so couldn't buffer the whole packet.
b. Each 1-wire has a 64 bit address, so 1/3 of RAM for those addresses.
WTF?? Brave browser rewards me for the ads that it shows. In March, I earned BAT6.326 (as seen on screen to the right), but I am only awarded BAT0.25, both in the pop-up "Your Reward Amount" as well as the actually add, so my grand total is now BAT16.500
Anyone seen something similar? Anyone any clues about what is going on?
