These devices are very simple and can only be programmed in assembler; perfect for learning! The ISP programmer is implemented on an ATtiny1607.\n\n## How to...\n\nCompile the source files for ATtiny1607 using the GNU toolchain for AVR (avr-gcc etc) and CMake. You must also install the device family pack (DFP) for the ATtiny1607 and place it in a folder named _device_pack_. Upload with _pymcuprog_.\n\nA simple CLI tool for communiacting with the programmer is in the cli folder. Install the tool with `go install isp`. For help type `isp --help`.\n\nThe example folder includes a simple led blinker program in assembler for the ATtiny15L. A simple Makefile for assembling, linking and uploading the program can be found in the same folder.\n\nWill add circuit diagrams later...\n\n## Further work\n\n- Document code\n- Write a cool(er) assembler program \n- PCB?\n\n## Resources\n\n- [ATtiny15L datasheet](https://ww1.microchip.com/downloads/en/DeviceDoc/doc1187.pdf)\n- [ATtiny1607 datasheet](https://ww1.microchip.com/downloads/en/DeviceDoc/ATtiny807_1607-Data-Sheet-40002030A.pdf)\n- [About AVR assembly](https://www.nongnu.org/avr-libc/user-manual/assembler.html#ass_isr)\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Faasmundn%2Fattiny-isp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Faasmundn%2Fattiny-isp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Faasmundn%2Fattiny-isp/lists"}
