The following are excerpts and results of emails with ‘basicchip’. Problem: Runaway BASIC program causes chip to lockup (can’t re-program). “Tried the Runaway Program procedure provided in the Forum, keep getting Com Port Unavailable Error (maybe I wasn't fast enough). But did stumble on something t...

ARM Stamp Doc issue: As of the ARMbasic.chm version downloaded on 4/18/20, the 'LPC11U37 Details' page shows: Pin J1-1, SOUT, IO(18), SP16 Pin J1-2, SIN, IO(19), SP17 The IO#'s are not consistent with the schematic or the LPC11U37 user's manual. SOUT connects to a TXD output of the LPC11U37, IO(19) ...

Attached is an Excel-97 spreadsheet (and a PDF version) that defines the pinout of the ARM Stamp. It includes Func/Names, SPxx numbers, Port numbers, IO( ) numbers, AD( ) numbers, and notes for each pin, as well as general notes, that pull together details from various sources. A good place to start...

The attached program will quickly test the IO lines on the ARM Stamp. To use the program, follow the prompts to select a full connector test, a single line test, a serial SOUT/SIN test, an AD test, or options to see/change the values of the IO Configuration Registers. The full connector tests genera...

Attached is an Excel-97 spreadsheet (and a PDF version) that defines the pins on most of the connectors on the DataLogger, a good place to start for any DataLogger project, includes both old and new connector numbers. Spreadsheet shows which IO require Firmware 8.37 to work correctly. See also "Data...

My initial testing also looks good, thanks for the help.

Attached is an Excel-97 spreadsheet that defines the pins on most of the connectors on the SuperPro, a good place to start for any SuperPro project. A PDF version is also provided. Correction: 8/7/20, spreadsheet shows DAC on J2-3, should be J2-2 ( P0.26) Attached is an easy to read .GIF file of a S...

SuperPro IO Test Program The attached program will quickly test all the digital IO lines by driving the 8 outputs on a selected connector with 8 different test signals. The IO is grouped into 6 connectors with 8 IO on J10, J12, J13, J14, and J15; and 6 IO on J9. The program generates 1 pulse per mse...

Serial Saga, Still have no luck getting TXD2 and TXD3 to work. Looking at the registers before starting the program and again at the "END" (before Reset, or Stop), can see the Function change for TXD1 from 0x.D0 (GPIO) to 0x.41 (Serial), and then back to 0x.D0 (GPIO) after Reset, as expected. Doing ...

Good news, the DOA board lives. You were right, it just needed some firmware, thanks. Using what you provided, I dug into the NPX manual and the LPC43xx.bas file to fix 8 more IO. The register programming is shown below: * &H40086184 = &HD4 ' IOCON pin mux for P3_1 * &H40086188 = &HD4 ' " P3_2 * &H4...
