700 us - 2300 us with 10 ms interval \"standard servo mode\"\n - 1000us - 2000us with 2500 us interval \"DJI mode\"\n\n### Adjusting limits:\n* With Blank (0xFF filled) EEPROM the limits should be 1000us - 2000us respectively for the standard servo mode\n\n* You can set separate limits for separate modes:\n\n** To adjust the limits press the Pulse width button (type on the silkscreen) until the 'bot' text appear.\n\n** Then push the PW button again and adjust the lower limit (500 us - 1500 us allowed).\n\n** Once done with adjusting the minimum pulsewidth press the PW again and the 'toP' text will appear.\n\n** Then push the PW button again and adjust the upper limit (1500 us - 3500 us allowed).\n\n** Push the PW once again and your settings will be saved which is indicated with a blinking done text. \n \n## Toolchain info\n\nSTM8 Standard peripherial lib from ST\n\nSTVP + Cosmic (planning to port SDCC and use openOCD and GDB for debugging)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmartonmiklos%2Fstm8_servotester","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmartonmiklos%2Fstm8_servotester","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmartonmiklos%2Fstm8_servotester/lists"}
