Recording Speed to SD Card

[ORANGEID]

Hi there

I was wondering if there any way to speed up the recording of images to SD card

I am using the arducam shield v2 with a Arduino UNO and the OV5642(2592x1944) currently it seems to take quite a while

If not possible to speed it up does switching to a raspberry pi help ?

Any help would be greatly appreciated

As you can see the Arducam SPI camera is designed for capturing still photos or short movie clips. The bottle neck is the SPI interface speed and the speed of Arduino board. With faster MCU like STM32 will helps, because it has DMA channel for both SPI camera and the micro-sd card controller.

Thanks For getting back to me so quickly, the STM32 sounds interesting i don't suppose you have any documentation about how to use to it with the v2 shield ?

Hi There

So I bought my self a Maple mini and trying to get this work, but having a little problem with the verify the code, haven't got to trying to upload it yet

system: osX 10.11 example code: ArduCAM_Shield_V2_Digital_Camera.ino hardware library: Arduino_STM32-master

this is the error message i am getting

In file included from /Users/----/Documents/Arduino/libraries/ArduCAM/ArduCAM.cpp:110:0: /Users/----/Documents/Arduino/libraries/ArduCAM/ArduCAM.h:661:2: error: 'regtype' does not name a type regtype *P_CS; ^ /Users/----/Documents/Arduino/libraries/ArduCAM/ArduCAM.h:662:2: error: 'regsize' does not name a type regsize B_CS; ^ /Users/----/Documents/Arduino/libraries/ArduCAM/ArduCAM.cpp: In constructor 'ArduCAM::ArduCAM(byte, int)': /Users----/Documents/Arduino/libraries/ArduCAM/ArduCAM.cpp:136:5: error: 'P_CS' was not declared in this scope P_CS = portOutputRegister(digitalPinToPort(CS)); ^ /Users/----/Documents/Arduino/libraries/ArduCAM/ArduCAM.cpp:137:5: error: 'B_CS' was not declared in this scope B_CS = digitalPinToBitMask(CS); ^ /Users/----/Documents/Arduino/libraries/ArduCAM/ArduCAM.cpp:144:21: error: 'sbi' was not declared in this scope sbi(P_CS, B_CS); ^

Is the any specific STM32 example for working with arducam ?

Any help would be greatly appreciated

Cheers

@james-oab Hi, We are very interested in your platform you are using.Can you tell us which platform your are using? Where can we download the Arduino_STM32 library? We hope work together with you. Regards. Arducam support team.

[james-oab]

Hi

The library I am using can be download from here, https://github.com/rogerclarkmelbourne/Arduino_STM32

I also requested help on there surport forum http://www.stm32duino.com/viewtopic.php?f=2&t=2906 They have point out that this issue is down the way that code use flash access but i haven't chance to loo into this yet - but i fear it maybe beyond me so any help would be greatly appreciated

Cheers

@james-oab Great, but what's your board platform? We plan to try it .

[james-oab]

Sorry forgot to add that

I am using a maple mini, this is where i bought it from https://www.ebay.co.uk/itm/272238622756

Many Thanks

@james-oab Hi, This board has no one to continue to maintain, we advise you not to use it. Regards.

[james-oab]

Ok thats, I did try compiling the code for few different board that reported the same issue ? Is there a STM32 board you do recommend ?

Thanks

James

@james-oab Hi,

At present,we have not use STM32 on Arduino IDE develop environment . If you want to use STM32, you can develop it on keil environment.

Regards,

[james-oab]

Ok thanks for getting back to me, do you have a library for the keil or would it be starting from scratch ?

@james-oab Please give us your email address and we will give you our camera driver code.
