Errors between program *238*LoRa_Remote* and *241*Receiver #52

Closed johncblacker closed 2 years ago

johncblacker commented 2 years ago

I'm using the MKRZERO board which has an onboard SD card holder/reader/writer. I'm using example "238" Remote Camera running on the MKRZERO sending (I wish) to example "241" running on Arducam esp32s uno psram. On the Remote Camera side I get the following messages: <<<<<<<<<<<<<< 238 remote cam messages >>>>>>>>>>>>>>>>> Beginning setup C:\Users\jobla\Documents\Arduino\JB-DUE-ARDUCAM-238_StuartCAM_LoRa_Remote_Camera\JB-DUE-ARDUCAM-238_StuartCAM_LoRa_Remote_Camera.ino SD Card detected OV2640 SPI interface OK OV2640 setup on I2C LoRa device found

So, I popped the card out and there are 10 .jpg files written to it but when I try to open them with "3d paint" the program indicates the file is corrupted. Eight of the ten files are 1K in size, the other 2 are 3k in size. I've tried opening several 1k and 3k to no avail. Any ideas? When I run the example arduino sd card sketch for the mkrzero it runs fine, but of course it's writting a very small text file then reading it back in and printing the contents. What do you suggest I do to troubleshoot the issue?

I cannot directly assist, the programs and library have not been tested on the particular hardware you are using. It does sound like issues with the RX side SD.

First test that the LoRa comms is working proplerly and reliably, see the examples in the \Reliable folder.

Then try some of the programs in the \Data Transfer folder. You can create a small file on the source SD that consists of a known sequence of bytes, such as a text file and see what the received file looks like.

OK, that'll be my next step. I've gone back to the DUE now since I received my sd breakout board today and installed it. I'm currently formatting an 8GB sd card and then will give it a go.

johncblacker commented 2 years ago

Getting very frustrated with this whole setup. Once I get the sd card working (card detected) then I get spi interface errors trying to get the camera initialized. Seems like it would be more stable if each device was on a separate SPI interface; but that's a lot of changing in your code.

johncblacker commented 2 years ago

Closing this and looking for a more stable solution.

StuartsProjects commented 2 years ago

Seperate SPI interfaces for the LoRa and SD card would likely help, however the 238 and 241 examples are very stable on the hardware it was tested on.

If there are issues with some Arduinos not being reliable when the LoRa and SD card are on the same bus, then the issues will with the hardware used or the SPI and SD libraries that Arduino provide for that particular board.
