How to modify pic of this board

[lifankohome]

I have nodemcu and esp32 boards, can i control the picture with arduino?

[andrei-tatar]

You should be able to, but you will need some very good soldering skills. I was actually planning on controlling this display with an ESP32, but I didn't got to it yet

[lifankohome]

That's great.

I found a way to control with arduino, and the pin map is like this (maybe it can help you):

And i also have a question, is there a way to re-program cc2510(Windows OS), so we can control the display by uart?

@lifankohome I did manage to get the led blinking. You can check the firmware folder (I used VS Code). I don't see why it wouldn't be possible.

[lifankohome]

Well.

I don't know how to compile your code and upload it to cc2510 by arduino. I can use Arduino IDE only.

[andrei-tatar]

You can just use vs code, I added the build/upload tasks and the binaries that do it. But you will need to build yourself a programmer out of an Arduino: https://sites.google.com/site/ericmklaus/projects-1/a-flash-programmer-for-the-cc2510

[lifankohome]

Perfect, I'll try it.

Hi!

I made a UNO programmer(the pin connections are same as your picture, the UART window can output the chip-id if i typing [1]), and I upload [firmware\build\main.hex] to UNO success (By CCpgmr.exe).

But the imagotag board not blink the led. Is something wrong?

[andrei-tatar]

Good question. Maybe try rebuilding the firmware. Last time I was playing with it, I was writing the EPD code so maybe comment that out.

[lifankohome]

I rebuild the firmware and upload, led still keeps off.

Then I test P2_1, it's always HIGH. I edit code in main():

void main(void)
{
  while (1)
  {
    delay(500);
    P2_1 = 0;
    delay(500);
    P2_1 = 1;
  }
}

save, make, packihx main.ihx to main.hex, upload main.hex by CCpgmr.exe...
But the led still keeps off. I test P2_1 again, it's always HIGH.

I connect P2_1 to GND, LED keep off, then connect P2_1 to 3.3V, LED keep off. can P2_1 control LED?

Now I suggest the program not run at all, and P2_1 can't control LED, I don't know why...

[andrei-tatar]

I would go and test but the boards I was using are in some box in the back of the garage (the joys of moving)...

[lifankohome]

That's great. Waiting for you ^_^

[lifankohome]

I bought a CC-Debugger... so i can debug the circuit directly...

[lifankohome]

Now P2_1 can turn LOW and HIGH with interval 1000ms, but the led don't blink at all.

The led only flash once while power on and off...

[andrei-tatar]

If I remember correctly you need to toggle both P2:1 and P2:2 (one enables the 5V boost ic and the other turns on/off the LED).

Try this:

  P2DIR |= PIN(1) | PIN(2);
  P2_2 = 1;
  while (1)
  {
    P2_1 ^= 1;
    delay_ms(500);
  }
