Hi all, Just a wee note.......I have an R6581T on it's way, and I think the VFD is ok (famous last words!), but decided to put together one of these OLED solutions anyway. Those that know me will know I like modifying/upgrading my gear! I have the .HEX file and have uploaded it to one of my BluePill STM32 boards, however, in regards to the toolchain my app of choice is Visual Studio (I don't use Eclipse) for everything including Win apps in VB, Arduino ATMEGA & STM32, so decided to try VisualGDB plugin for Visual Studio (VS 2022) and lo & behold I was able to import Mickle T's source, set up the configuration and compile a .HEX file of my own. Looking forward to receiving my OLED and trying the original Mickle T HEX file as well as the one compiled by Visual Studio.....see if it works! Anyone else tried this?.......so far VS VisualGDB plugin is looking workable! UPDATE: No R6581T yet so scoped the STM32 pins with original HEX, got some waveforms, then uploaded my own HEX file from VS and scoping them again I get exact same waveforms, so looking good. Original HEX file = 29.6KB VS HEX file = 39.9KB, so I can only assume VS debugging overheads & optimization. I haven't started looking at Mickle T's source code at all, but looking forward to having a look around, and knowing me tweaking. UPDATE: The VS2022 compiled project does work with the R6581T & OLED.

Hi all, Below is a link to my conversion of Mickle T's original source project to a Visual Studio project (Windows). It compiles to a hex file just fine..........Untested though, although the uploaded HEX file does seem to scope the same signals on the STM32 board. No source changes were necessary at all. VS2022 64-bit, Community Edition Requires VisualGDB plugin for VS (30-day demo version will do) - https://visualgdb.com https://github.com/Ian-Johnston/OLED_SSD1322_DMA Ian. |

Here is a zip archive with that H730 LTDC TFT replacement display project. As i have some ready to use PCBs left i thought about making them into kits, but i don't have time to support that. Regards, Dieter |

Here's my OLED conversion photos below. And my YT video: https://youtu.be/QyP6tK9EIsg I also modified the OLED display (SSD1322 iREF pin) to increase the brightness just a touch to compensate for the smoked perspex. Instructions are in the video. A big thanks to Mickle T......what a difference this has made to my R6581T. Ian. |
