Moved to a new server Due to a problem on the older server provided by my Uni's ICT department, I decided to move this wiki to the newer server. However, now I am having problems updating (some of?) my wiki pages. Need some time to check this out, but at the moment I think I am affected by

Latest HC06 AT firmware I am trying to create an 8051 code library for HC06 bluetooth module. I have done one for my my1barepi library, so I thought that would be easy. Boy! Was I wrong! It turned out that the AT firmware on the latest HC06 module have been upgraded. The old ones do not need any CR/LF pair (the new ones do) and the AT command for changing name requires a ':' i.e.

Re-Post: Cron Note: This is taken from my previous blog - Published on: Jul 11, 2011 @ 10:35 Sounds very computer-ish isn't it? Well, it is... it's actually a scheduling table, something that computer system admins are very familiar with. It's nothing fancy, I could have written this in my wiki, which is what I usually would have done.

RGB 80x160 OLED ST7735S I bought this display module a while back, but never got the chance to test it out. I have multiple platforms to test it with: (1) Pi Zero (2) 8051:stc12 (3) Maker Uno (4) ESP32 (5) Pi Pico. While I figure out what I am going with, I just want to put some basic info so I can refer to it later.
