Were you able to decode the radio stream using MicroPython? I know there are Arduino solutions.

Re: OLED with SSD1322 controller
In case anyone is interested, I wrote a Micropython driver for the SSD1322. https://github.com/rdagger/micropython-ssd1322 The library supports drawing lines, shapes, text, sprites, QR codes and images. All code is documented and there are demo examples. Tested on Raspberry Pi Pico W with 5.5 inch g...

Re: FrameBuffer blit palette
Code examples are always more helpful to me rather than explanations. As soon as I saw your code it became clear.pythoncoder wrote: ↑Mon Aug 08, 2022 8:07 amI'm glad you've sorted it. I guess the official docs are rather terse (my fault).

Re: FrameBuffer blit palette
@pythoncoder So helpful, thanks! I understand now. Since GS4 stores two 4-bit grayscale colors per byte, the palette buffer only needs 1 byte for mono to GS4 conversion (1 nibble for background and 1 nibble for foreground). Here's my working code: bg, fg = 0, 15 palette = FrameBuffer(bytearray(1), 2...

FrameBuffer blit palette
I’m trying to blit a MONO_VLSB framebuffer onto a GS4_HMSB framebuffer. The image shows up as very dim because instead of converting the white pixels from 1 to 15, they are remaining at 1 which is a very dark gray on the grayscale. I tried setting up a palette framebuffer to handle the conversion, b...

Re: Bad flash
I can't help with expereince but there are a number of comments in esp-idf code and docs about chip support. you might want to double check the docs/ code in that component to be sure they have support for your proposed chips. This has some references to sizes above 32Mb for example: https://docs.e...

Re: Bad flash
Not all ESP32 boards have the board level shield. The TTGO T8 doesn't have one. The lack of shield will make it easier to replace the flash chip although a metal cover may have prevented the damage in the first place.

Re: Trying SSD1305 display from adafruit
I haven't worked with the SSD1305 but I did write a Micropython library for the SSD1309 . I have not looked at the datasheet for the SSD1305 but you might get lucky. Just make sure to specify the correct width and height when you initialize the display. Regardless, it would probably be easy to modif...

Re: Bad flash
I should have mentioned I already cleaned the board with MG Super Wash and I reflowed all the components.

Bad flash
I have an ESP32 (TTGO T8) monitoring my vegetable garden. I left the cover off its enclosure last night and it rained. This morning the code had crashed and I was unable to get REPL access via USB. I hooked up a serial connection and still cannot get Rshell to connect. When I use ESPTool, I get the ...
