08H = 00 (MSB left)0FH = 10 (MSB left)E8H = 01 (MSB left)EFH = 11 (MSB left)By breaking up a transmission byte into four symbols, we can then send them down the serial port without delays in transmission and the circuit will reconstruct the byte in SPI serial format, with a synchronous clock and a slave select signal. Spi Serial Flash Programmer Schematic For Windows Qspi Flash ProgrammerĪnd it all works from a standard serial port, on any platform, and can be operated by human-readable strings from a serial terminal application such as Putty or Kitty, or even Hyperterminal. It can talk to and read SPI devices, displays and peripherals as well. It’s an SPI bootstrap programmer so that you can program a bigger, better SPI programmer that can do much more than just program other chips. BUILD TIME: 2 HOURSDIFFICULTY RATING: IntermediateHave you ever wanted to control a small Arduino or Raspberry Pi display straight from your PC? How about reading accelerometers from a chip for a programming project? Or have you wanted to build your own in-system programmer so you can make the leap to embedded projects without all the complexity of having to remove chips so you can plug them into the burner?Then this project is for you. Everything you ever wanted to know about SPI and a few things you didn't, all controlled from the comfort of your PC.
