NP-41 Emulator (may be)
Hello, I am back and plan to stitch w/ my soldering station again.
I had found the perfect MCU for a nonpareil HP-41C emulation. The TI MSP430FR6989 . 128K FRAM (non-volatile memory) . 2K static RAM . Direct LCD segment driver . sub uA power consumption during sleep . typical 100ua / Mhz active I had done prototyping w/ a development board which has a 6 digit 14 segment display. I need to summon an additional launchpad MSP430FR4133 so that I can have an additional 6 digits. There is no hardware keyboard yet, I am using a UART to send keys over. Here is a video for a 9, sin, cos, tan, (and reverse) forensic program, entered and executed. It will be a long way a build this into a standalone. My main task now is to try and find a 12 digit 14 segment LCD display. |
