Live OV7670 now runs on WAVGAT MCUs. Frame rate is twice as fast since it runs at 32Mhz (Atmel based Arduinos run at 16Mhz).

Thanks!

could you use STM32F103C instead ?! it's 4.5 times faster than nano.

Hey! I got it working with it but I wasn't able to get it to sync up as perfectly as with an Arduino. The maximum framerate I got was 15fps. github.com/indrekluuk/LiveOV7670_stm32-arduino With Arduino, I was able to ignore pixel clock and could just blindly read pixel data in sequence. With STM32F103C I had to check pixel clock for every pixel read and that wastes time compared to Arduino. I read somewhere that actually, it should be possible to do the pixel read in hardware level with the STM32 controller. That should speed it up considerably, but I haven't had time to experiment with it.

Amazing. I like to so your devolopment with these camaras. ;)

hi can you help me to get this working with ili9488 480x320 lcd? please help me, thank you.

@aimless3827 5 лет назад

You gotta try it with esp32 and pull it up to 25-30fps.

@IndrekL 5 лет назад

Yes, I have already bought one, but I haven't had time yet. At some point in the future I want to try it.

i can use 1.77 150x128 display in this project?

@adventuremania273 2 года назад

Hello. Tell me, how is the maximum frequency of the signal measured if 8 megahertz is strictly indicated in the library? // pin 3 to 8Mhz (LiveOV7670Library clock) #define OV7670_INIT_CLOCK_OUT \ pinMode(3, OUTPUT); \ TCCR2A = _BV(COM2B1) | _BV(WGM21) | _BV(WGM20); \ TCCR2B = _BV(WGM22) | _BV(CS20); \ OCR2A = 1; \ OCR2B = 0

Can we process 20 Fps through atmel based nano.... I mean what if wavgat is not available as it is showing ‘out of stock’ in alliexpress app

@goldenstarmusic1689 5 лет назад

Where do you get these boards?

@IndrekL 5 лет назад

I designed them myself in KiCAD and ordered form oshpark.com (you could also use any of the Chinese manufacturers as well). If you download the LiveOV7670 project then in the "LiveOV7670/pcb/kaamera_ja_ekraan/" folder are this board files. If you zip the "gerber" folder in "LiveOV7670/pcb/kaamera_ja_ekraan/" then you can upload it to oshpark.com and get it manufactured.

Здравствуй, можно подобную схему собрать на ардуино мини про с ттл камерой и дисплеем 0.85 дюйма?

greate job

I have IPS display based on ST7789 240x240 whith no CS pin, but still cant change your code on it (

@IndrekL 4 года назад

Hey! My code is specifically designed to work with this 1.8 inch screen you see in this video.

Hey Code please

@don_jotao 5 лет назад

Hi there! I don't remember if I did tell you before, but I really admire the work you've done with the content for this channel, it's amazing and I'm very thankful for looking at your vídeos. It's a big opportunity for me to learn a little bit more about the arduino world. I'd keep learning from this method and I really would like to meet you to say Thank You. Maybe we can chat. Now I have a question: have you ever thought about recreating this project with NodeMCU-Esp32? Again, thank you!!

@IndrekL 5 лет назад

Thanks! I have bought this ESP32 board and at some point in the future I will try to make it work on it: www.aliexpress.com/item/ESP32-ESP-32-ESP32S-ESP-32S-CP2102-Wireless-WiFi-Bluetooth-Development-Board-Micro-USB-Dual-Core/32867696371.html?spm=a2g0s.9042311.0.0.3da24c4dFCnvxP But I can't use NodeMCU firmware since it uses Lua scripting language and not C/C++. Timing is really important for the camera interface and I have to do it in C/C++.

How to make it can view in smartphone

@IndrekL 5 лет назад

In the future I will try to make it with the ESP8266 wifi module. But since data will be transferred over UART it will be much slower. Similar frame rate as in my previous "image over USB to PC" video.
