Instead of the HP-15C's complex mode, the HP-32S had just one mode but allowed the CMPLX key to be used as a prefix to the other functions in much the same way other calculators used HYP or ARC prefixes on trigonometric functions. Obvious error messages (like Divide By 0.).Variables instead of numbered registers (see below.).Complex Arithmetic functions (see below.).(With windowing to view long binary numbers.) Binary, octal, decimal and hexadecimal bases.Numeric integration (of RPN functions.).Basic scientific functions including hyperbolic functions.

You can also install Energia and use the GCC compiler in the bundle. Easiest and least expensive way is to get a TI LaunchPad G2 and use it as a programmer.ĭownload and install GCC compiler for MSP430.

Software and Programming ToolsĪcquire a MSP430 MCU programmer. The rest of the components including the tactile switches and other passive components can be soldered the usual way. This is because the LED modules on the front side block the holes. This has to be done on the IC component (back) side instead of the usual solder (front) side. As the other side of the through holes are blocked by the LED modules, they will not fit without trimming the pins. Next we need to trim the IC pins before placing them onto the PCB. This will allow proper placement of the ICs. There are three of them and when finished soldering, use a wire cutter / trimmer to trim off the pins on the other side. It is best to place and solder the LED modules first. To address this issue, both the ICs and the LED modules need to have their pins trimmed so that they do not protrude into the other side of the PCB. The ICs and LED modules actually intrudes into each other's footprint as they are through hole components. The two layer PCB was designed to minimize component space, and as such, components are placed on both side of the PCB.

LED modules are direct driven w/ pulsing to eliminate the need of current drivers. LED multiplexing is done w/ a 74hc164 shift register. The objective of the project is to re-create popular 70's RPN calculators such as the HP Woodstock and Spice series.Īnother goal of this project is to have the design as simple as possible so that the project can be re-produced by the average electronic hobbyist.Ī low power MSP430G2553 is used in this project. This is a hardware realization of Eric Smith's Nonpareil microcode simulator. Msp430 Based Calculator Emulator for the HP-21, HP-25C, and HP-33C Calculators.
