[](https://www.buymeacoffee.com/singhamiteK) ### FASTUSBasp programmer for AVR Microcontrollers [](https://gitter.im/FASTUSBasp/Lobby?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) This is the fast ISP programmer for AVR MCUs based on cheap stm32f103c8t6 aka `blue-pill` board with usb-to-serial support. ### Release - v1.0.0: https://github.com/amitesh-singh/FASTUSBasp/releases/tag/v1.0.0 #### FastUSBASPv2 board  #### Perf board  ### Correcting wrong pullup at USB D+ This blue pill board has wrong pullup resistor at usb D+ line. You might need to fix it before using blue pill as an AVR programmer. Refer to this guide: [http://amitesh-singh.github.io/stm32/2017/10/09/correcting-usbpullup-resistor.html][fixpullup-link] ### how to upload firmware #### blue pill board with correct pullup at USB D+ line Download the binaries from https://github.com/amitesh-singh/FASTUSBasp/releases/tag/v1.0.0 If you have fixed the pullup at D+ line, use `fastusbasp.bin` The pre-compiled binary is at `fastusbasp.bin`. ```shell $ st-flash write fastusbasp.bin 0x08000000 ``` #### blue pill board with wrong pullup at USB D+ line In case, you did not fix the wrong pullup at D+ line, use `fastusbasp-wrongpullup.bin` binary instead ```shell $ st-flash write fastusbasp-wrongpullup.bin 0x08000000 ``` ### How to use #### ISP connections It uses SPI2 to communicate to AVR. Blue pill | AVR --------- | ------- PB15 | MOSI PB14 | MISO PB13 | SCK PA8 | RST 5v or 3.3v | 5v GND | GND #### Serial connections Serial ports are `PA10`(RX) and `PA9` (TX). This can be used to debug AVR Microcontrollers. Blue pill | AVR --------- | ------- PA10 | TX PA9 | RX All pins SPI2(PB15, PB14, PB13), Serial(PA10, PA9) and RST(PA8) used are 5V tolerant. #### udev rule Refer to [udev/README.md](udev/README.md) ### On plugging to PC #### Linux When you plug this device to PC, you should get following message on`dmesg -wH` ```shell [Jan20 13:31] usb 3-1.1: new full-speed USB device number 5 using xhci_hcd [ +0.107774] usb 3-1.1: New USB device found, idVendor=16c0, idProduct=05dc [ +0.000004] usb 3-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ +0.000002] usb 3-1.1: Product: fastusbasp [ +0.000002] usb 3-1.1: Manufacturer: http://amitesh-singh.github.io [ +0.000001] usb 3-1.1: SerialNumber: AARAV [ +0.040797] cdc_acm 3-1.1:1.0: ttyACM0: USB ACM device [ +0.000804] usbcore: registered new interface driver cdc_acm [ +0.000000] cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters ``` `/dev/ttyACM0` is the serial port. #### Windows - Download Zadig (https://zadig.akeo.ie/) - Insert device to USB. Wait until windows can't install it. - Launch Zadig - Select in Zadig our device from ComboBox - Select driver Type libusbK - Press Install Driver - Wait until Zadig is done with installing driver and that results into Windows to detect the device. ### Probe AVR ```shell $ avrdude -c usbasp-clone -p m16 avrdude: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.00s avrdude: Device signature = 0x1e9403 (probably m16) avrdude: safemode: Fuses OK (E:FF, H:D8, L:CF) avrdude done.

To program `stm32f103` via USART, you need to set `BOOT0` as `1` and leave `BOOT1` as `0`. Connect any usb to uart converter device and connect PA9 to RXD and PA10 to TXD and connect GND. ```shell $ make fastusbasp-serialupload ``` ### Links - http://amitesh-singh.github.io/stm32/2017/05/21/FASTUSBasp-programmer-avr.html - https://hackaday.io/project/21189-fastusbasp-programmer-for-avr [fixpullup-link]: http://amitesh-singh.github.io/stm32/2017/10/09/correcting-usbpullup-resistor.html
