PCBLaserFirmvare | Laser PCB Exposer based on a MSP430G2553 MCU

PCBLaserFirmvare is a C library typically used in Internet of Things (IoT), Arduino applications. PCBLaserFirmvare has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Firmware for my Laser PCB Exposer based on a MSP430G2553 MCU. ? - reports version. XPix: - sets X size of PCB to number of pixels. NOTE: the X size MOD 7 must be 0, ie. padding must be added to satisfy the 7 pixels per byte format. YPix: - sets Y size of PCB to number of pixels. Start - starts rendering, rendering data format is 7 pixels per byte offset by 0x3B, 0x1A in the stream cancels rendering. Each row starts with row number in ASCII format followed by a semicolon, then the rederering data terminated by 0x10. MoveX: - moves X-axis , 1 step = 1 pixel. MoveY: - moves Y-axis , 1 step = 1 pixel for belt drive - may be more steps if ballscrew drive. MoveZ: - moves Z-axis (focus) , not supported by MKII hardware. Laser:<0|1> - 0 = laser off, 1 = laser on. Power: - set laser current, n = 0-4095 (a 12-bit DAC is used). ZeroAll - resets internal position counters (X, Y, Z) to 0. HomeXY - homes X and Y axes. HomeX - homes X axis. HomeY - homes Y axis. HomeZ - homes Z axis, not supported by MKII hardware. Echo:<0|1> - 0 = echo off, 1 = echo on. XHome: - start offset for X-axis related to home position. YHome: - start offset for Y-axis related to home position. XBComp: - set backlash compensation to number of . 1 pixel @ 1200 DPI is ~21.2 µm, a little less than 1 mil (25.4 µm). Communication is via serial @ 38400 baud, 8 bits, 1 stop bit, no parity and with hardware handshake (RTS/CTS). This project can be directly imported into TI's cloud based IDE available at dev.ti.com, there is no need to download and set up a local development environment in order to compile and upload code. A MSP-EXP430G2 LaunchPad can be used as a programmer, remove the MCU from the launchpad and connect P5 (PGM) to the corresponding pins on the launchpad. NOTE: for the MKII revision the LaunchPad itself can be used as the controller.
