 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

A number of people have alerted me (thanks) to a few issues with the UBW32 version of MMBasic related to I2C and frequency/counting. I have fixed these in the next version of MMBasic but the fix required a rearrangement of the I/O pin allocations for the UBW32. As a result I thought it best to give you a "heads up" as to the changes that are imminent in ver 3.2 (due out in about 4 weeks). The details are: - Pin 11 will move to E8 - Pin 12 will move to A15 and this pin is also SDA for the I2C function - Pin 13 will move to A14 and this pin is also SCL for the I2C function - Pin 14 will move to E9 - Pin 31 will move to D10 - Pin 32 will move to D9 - Pin 37 will move to D11 - The card enable signal for the SD card (SC_CS) will move to D8 I2C will then work with SDA on pin 12 (A15) and SCL on pin 13 (A14). Pins 11 (E8), 12 (A15), 13 (A14) and 14 (E9) will then work correctly as frequency/counting inputs. If anyone wants to jump the gun and try a stable beta version of 3.2 for the UBW32 please send me an email and I will be happy to send it out. Geoff Geoff Graham - http://geoffg.net |
