Chips for making Monitors
I mean some ASIC. I have a board with a MST717C-LF chip, the chip takes VGA signal and convert it to a 800x480 RGB TFT, the chip is programmable and it has a 25X SPI eeprom. But I...

SSD2119 4-wire SPI
Quote:You're not using the external read and write instructions because you're using the SPI interface. But the SPI talks to internal registers, and register 22h is the read/write...

SSD2119 4-wire SPI
This lcd has built in frame memory, so you can use it with an avr!

SSD2119 4-wire SPI
Quote:I dare say you cant read back data and why would you want to? It is probably considered too slow to read via spi. For some effects it's crucial to read data back, for...

SSD2119 4-wire SPI
Quote:Page 55 of the datasheet; also the note in section 7.4. It looks like it's a straight read. There is no info in page 55! In page 20 there is a table that said that the RD...

Step motor datasheet
Quote:Ali, I asked two times to do some measurements. Not keep you busy but those measurements reveal the SEQUENCE of the windings. And that's what you need. IMO. I cannot see...

Step motor datasheet
I have still no luck! This is the most weird stepper motor that I have ever seen! New ideas are welcome.

Step motor datasheet
It said you need 10 steps, and the steps are repeating! See the pattern.Quote:Three ohms at 3 voltrs is going to need an amp per phase. And I had just paralleled two drivers...

Step motor datasheet
Quote:Dont try to step faster than a step every 5 ms or so at first. I'm using a 1 second delay for each step!(see the code)

Step motor datasheet
I have built a circuit with ULN2803 for Low side switches and UDN2983 for high side. This is the software that I had written, /* * _5_phase_stepper_motor.c * * Created: 3/21...

Step motor datasheet
Quote:To distinguish a 5-phase motor from other motors with 5 leads, note that, if the resistance between two consecutive terminals of the 5-phase motor is R, the resistance...
